15 Best B2B Data Enrichment Companies and Providers Compared in 2026

The market is crowded and inconsistent. Over 50 vendors sell some version of "B2B data," most of them buying from the same handful of upstream sources, wrapping a different UI around it, and charging wildly different prices for nearly identical records. If you're hunting for alternatives to Clearbit or a better CRM data cleaning tool, the hard part is telling the aggregators apart from the sources.

Here's what data enrichment actually is, for anyone just getting started: you take your existing B2B records, names, companies, partial emails, and fill in the gaps with verified emails, phone numbers, firmographics, and more from external sources. Every sales and marketing team needs this, because a list that has not been enriched or verified since it was exported is a bounce rate waiting to happen.

This ranking covers data enrichment companies and providers: who owns or aggregates the data, what they charge for it, and which ones resell each other. That is the vendor-selection question you answer once, at purchase. The companion page, best data enrichment tools for 2026, answers the operating question of which tool, software or platform your reps log into every day. The two lists overlap on names and differ on the question they settle, so read this one when you are deciding whose data you are buying and that one when you are deciding what to buy a seat in.

“Organizations with high-quality B2B data are 2.5x more likely to exceed revenue targets, yet 44% of companies still rely on a single data provider.”

We ranked 15 data enrichment companies across five criteria that actually matter: architecture, coverage, pricing transparency, integrations, and ease of use. No vendor paid for placement. No affiliate links.

How were these data enrichment providers ranked?

These 15 providers were ranked on five weighted criteria you can verify yourself from each vendor's own documentation, pricing page and free trial, without taking anyone's word for it. Every price on this page was read from the vendor's own pricing page on September 1, 2026, and where a vendor publishes nothing this page says "publishes no price" rather than repeating a number it cannot source:

• Architecture (30%): single proprietary database, waterfall across many providers, or raw API. This predicts coverage better than any feature list.
• Coverage (25%): which fields actually populate (email, phone, title, headcount, industry) versus which merely exist in the response schema
• Pricing (20%): published cost per enrichment, pricing transparency, and minimum commitments
• Integrations (15%): CRM connectors, API quality, workflow compatibility
• Ease of use (10%): time to value, interface quality, learning curve

Every accuracy percentage in this article is the figure the vendor itself publishes or that appears in publicly reported results. Cleanlist's own 98% verified emails and 85% direct dials are product specifications, not the output of a head-to-head we ran against these companies. Run your own sample on your own segment before you commit, because coverage swings enormously by industry and geography.

Looking for tool-level comparisons rather than provider or company rankings? See the companion roundup: 11 data enrichment tools compared for 2026. This post ranks the companies and providers behind the data, which is the question you settle once at purchase. That one ranks the tools, software and platforms sales and RevOps teams operate day to day.

Which data enrichment providers made the top 5?

Which data enrichment provider is best for each use case?

• Best for email accuracy: Cleanlist, specced at 98% verified emails across a 25+ provider waterfall, with verification run on the lookup itself
• Best for enterprise + intent data: ZoomInfo, largest proprietary database (300M+ contacts) with built-in intent signals
• Best for startups on a budget: Apollo, data + outreach in one tool starting at $59/user/month with a free tier (we counted what 38 vendors' free plans actually release in the B2B data free tier census)
• Best for European data: Cognism, deepest EMEA coverage with GDPR compliance built in
• Best for HubSpot teams: Clearbit (Breeze Intelligence), native HubSpot enrichment with website visitor identification
• Best for waterfall enrichment: Cleanlist, queries 25+ providers per lookup so no single source gap kills your coverage
• Best for CRM data cleaning: Cleanlist, automated deduplication, normalization, and multi-source verification
• Best free plan: Apollo, a $0 plan with email sequences included and a published fair-use ceiling of 10,000 credits per account per month
• Best for developers: People Data Labs, raw API access to 1.5B+ records on usage-based self-serve pricing
• Best for direct dials: Lusha, fast Chrome extension with strong phone number coverage, and one of the upstream providers inside the Cleanlist waterfall

What are the top data enrichment companies in 2026?

The top data enrichment companies in 2026 are Cleanlist, ZoomInfo, Apollo, Cognism and Clearbit (now HubSpot Breeze), and they split cleanly on whether they own the data or orchestrate someone else's. ZoomInfo, Apollo and Cognism own proprietary databases and sell access to them. Clearbit sells enrichment inside HubSpot. Cleanlist owns no database at all: it is a waterfall company that cascades every record through 25+ upstream providers, charges 1 credit per verified email, 10 per direct dial, 11 for both and 0 credits for search, and verifies the winning address by syntax, DNS and MX, and an SMTP handshake before it lands. On prices read from each vendor's own page on September 1, 2026, Apollo starts at $49 per user per month and Cleanlist at $79/mo, while ZoomInfo, Cognism and Clearbit publish no price at any tier. Google's own shortlist agrees on the shape of that list: on September 14, 2026 the AI Overview for "best b2b data enrichment providers" named ZoomInfo, Apollo, Clay, Cognism, Clearbit, HubSpot, Instantly, People Data Labs and Cleanlist, and cited cleanlist.ai as one of its nine source domains.

What is the difference between a data enrichment company and a data enrichment tool?

A data enrichment company is the vendor whose data you are ultimately buying. A data enrichment tool is the interface your team logs into. The distinction matters because several tools resell the same upstream companies, so two products that look different on a feature grid can hand you the same record. Cleanlist is explicit about which side it sits on: it is an orchestration layer rather than a data company, and it names the providers it buys from, including Wiza, Hunter, Prospeo, Findymail, LeadMagic, Lusha, Datagma and Crustdata. That is why this page ranks companies and providers while the companion page, 11 data enrichment tools compared, ranks tools, software and platforms. Ask any vendor how many upstream sources it queries per contact before you compare prices, because that number predicts your fill rate.

What are the best B2B data providers for clean, enriched data with no preprocessing?

Clean, enriched data with no preprocessing means the record is usable the moment it lands: the email already verified, the job title already normalized, the company already matched to a domain, with no dedupe, merge or validation pass of your own in between. Cleanlist is built for that shape. It checks every returned address by syntax, DNS and MX record, and an SMTP handshake before the row is written, flags catch-all domains rather than passing them through as valid, normalizes messy job titles with Smart Agents, and merges the best value for each field across the 25+ providers it queried, so one reconciled row arrives rather than five conflicting ones. A row that resolves to nothing is not billed. Cleanlist charges 1 credit per verified email, 10 per direct dial, 11 for both and 0 for search, from $79 a month for 1,500 credits and 2 seats. Cognism and ZoomInfo also ship normalized records, because a single owned index has no merge problem to solve, and they inherit that index's gaps instead. Apollo and People Data Labs return raw fields you reconcile yourself.

Who are the top providers for waterfall enrichment of lead data?

Waterfall enrichment sends one lead through many data providers in sequence and stops at the first verified match, so the top providers for it are the ones that orchestrate rather than the ones that own an index: Cleanlist, Clay, FullEnrich and BetterContact. Cleanlist runs 25+ providers on every record with verification as the final gate, charges 1 credit per verified email, 10 per direct dial and 0 for search, bills nothing on a miss, and starts at $79 a month for 1,500 credits and 2 seats, with seats bundled into the plan rather than billed per head. Clay exposes the cascade as a table you configure yourself, at $185 a month on Launch and $167 a month on annual billing (clay.com/pricing, September 1, 2026). FullEnrich and BetterContact sell the cascade as a standalone credit product. Single-index vendors such as ZoomInfo, Apollo and Cognism are inputs to a waterfall rather than substitutes for one, because a cascade across several of them recovers rows any single one of them returns blank.

1. Cleanlist

Cleanlist: Best for teams that need a verified contact record without contracting five data vendors themselves. It runs waterfall enrichment across 25+ providers and checks every returned address by syntax, DNS and MX record, and an SMTP handshake, at 1 credit per verified email, 10 per phone number and 0 for search, starting at $79/month with seats bundled into the plan rather than billed per head.

Cleanlist doesn't maintain a single database. Instead, it uses waterfall enrichment to query 25+ premium data sources for every lookup. If provider 1 doesn't have the email, it tries provider 2, then provider 3, and so on down the cascade.

The result is a higher fill rate than any single-source tool, with every email verified before delivery.

What sets it apart:

• Waterfall enrichment: 25+ data sources queried per lookup. No single point of failure.
• 98% verified emails: every address is checked on the lookup itself, by syntax, DNS and MX record, and SMTP handshake, with catch-all domains flagged rather than passed through silently.
• People Search: build lists from scratch with structured filters for job title, seniority, headcount, industry, country, and past companies. Search itself costs 0 credits, so you only pay when you enrich.
• ICP Scoring: score every lead 0 to 100 against your Ideal Customer Profile automatically.
• Smart Agents: normalize job titles and run per-row AI research columns without manual cleanup.
• Credit-based pricing: pay for what you use. No annual contract. No per-seat fees.

Strengths:

• Highest stated verified email rate in this ranking (98%)
• Flexible pricing works for teams of 1 or 100
• People Search lets you build lists from zero, no existing data required
• Smart Agents clean and enrich fields that no provider returns

Weaknesses:

• No built-in outreach or email sequences
• No intent data signals
• Newer brand with less market recognition than ZoomInfo

Pricing: Credit-based, and the credit table is published. A verified email costs 1 credit, a phone costs 10, and a full contact record (email plus phone plus data) costs 11. People and company search cost 0 credits. Every new workspace opens on Scale for 14 days with 250 credits, three seats and no card. After the trial, plans are Free (30 credits/mo, no card), Starter $79/mo, Pro $229/mo, and Scale $599/mo, with 25% off on annual billing. See pricing.

Best for: RevOps teams, agencies, and anyone who's sick of bounced emails and wrong phone numbers. Especially strong for teams that need to build lead lists from scratch or clean existing CRM data.

2. ZoomInfo

ZoomInfo: Best for enterprise organizations buying intent data, org charts and a single vendor relationship. It sells access to the largest owned B2B database in this ranking, 300M+ contacts with Bombora-powered intent and conversation intelligence, and publishes no price at any tier (zoominfo.com, September 1, 2026), so the roughly $15,000/year floor quoted everywhere is buyer-reported.

ZoomInfo is the market leader. Full stop. Largest proprietary B2B database, most mature intent data product, and the brand recognition that makes procurement teams comfortable signing six-figure contracts.

But that recognition comes with enterprise pricing. And enterprise complexity.

Strengths:

• 300M+ contacts, 100M+ company profiles, the biggest proprietary database
• Intent data that shows which companies are actively researching your category
• Full platform: sales engagement, conversation intelligence, website visitor identification
• Enterprise-grade security, SSO, compliance features

Weaknesses:

• Pricing starts at $15K/year and scales quickly to $40K+
• Annual contracts with auto-renewal make exiting painful (sound familiar?)
• Single-source database means unavoidable data decay and gaps
• You have to talk to sales before you can even budget for it

Pricing: ZoomInfo publishes no price at any tier (zoominfo.com, September 1, 2026), so every figure here is buyer-reported: SalesOS Professional from roughly $15,000/year, Advanced near $25,000/year, Elite with intent at $40,000+/year. Per-seat fees apply.

Best for: Enterprise organizations with budget, teams that need intent signals, companies that want everything from one vendor. If ZoomInfo's pricing is out of reach, see our breakdown of the best ZoomInfo alternatives or a direct Cleanlist vs ZoomInfo comparison. For a full cost breakdown, read our ZoomInfo pricing guide.

3. Apollo

Apollo: Best for early-stage teams that want prospecting, enrichment and outreach in one tool. It puts its own contact database behind built-in sequences, a dialer and Salesforce and HubSpot sync, on a $0 plan, with paid seats from $49 per user per month on Basic (apollo.io/pricing, September 1, 2026).

Apollo grew fast by combining a large contact database with email sequences, a dialer, and a Chrome extension, all at a price point that startups can actually afford. It's the "good enough at everything" play, and honestly? For a lot of early-stage teams, good enough is exactly right.

Strengths:

• Transparent pricing at $49-99 per user per month, accessible for small teams
• All-in-one: data + sequences + dialer, no need to stitch together three different tools
• $0 Free plan whose published fair-use ceiling is 10,000 credits per account per month for non-paying accounts
• Clean interface with fast time to value

Weaknesses:

• Reported email accuracy around 80%, which shows up as a higher bounce rate on cold lists
• Limited direct dial phone coverage compared to ZoomInfo or Cleanlist
• Single-source database with the same gap problems as ZoomInfo
• Platform optimizes for outreach features; data quality is secondary

Pricing: Free at $0, Basic $49 per user per month, Professional $99 per user per month, Enterprise on request. Read from apollo.io/pricing on September 1, 2026. Apollo does not publish a single "free credits per month" figure; the 100-credit number that circulates in comparison posts is not on its pricing page today, and what Apollo does publish is a fair-use ceiling of 10,000 credits per account per month for non-paying accounts.

Best for: Early-stage teams with limited budget who want one tool for prospecting and outreach. See how Apollo stacks up in our Cleanlist vs Apollo comparison, browse Apollo alternatives, or read our Apollo pricing guide.

4. Cognism

Cognism: Best for companies selling into Europe where GDPR compliance is not optional. It runs human phone verification (Diamond Data) and DNC screening across EU and UK lists and includes five seats in each of its two named prospecting plans, and publishes no dollar price on either (cognism.com/pricing, September 1, 2026).

If you're selling into EMEA, Cognism is the strongest option. Period. Their database has deeper European coverage than any US-based competitor, and GDPR compliance is baked into the product from the ground up, not bolted on as an afterthought.

Strengths:

• Best European data coverage in the market
• GDPR-compliant by design, with consent-based data collection
• Phone-verified mobile numbers (Diamond Data) for direct dials
• Intent data through Bombora partnership

Weaknesses:

• Smaller US database than ZoomInfo or Apollo
• No published price at any tier, and buyers report $8-15K/year
• Limited data transformation or enrichment depth beyond contact info

Pricing: Cognism lists two sales-prospecting plans by name, Standard and Pro, each with five seats included, and publishes no dollar price on either (cognism.com/pricing, fetched September 1, 2026). Buyers report $8-15K/year, typically 40-60% less than ZoomInfo.

Best for: Companies selling into European markets where GDPR compliance is non-negotiable. For a full cost breakdown, read our Cognism pricing guide.

5. Clearbit (now Breeze Intelligence)

Clearbit (now Breeze Intelligence): Best for HubSpot-native and product-led teams that want enrichment to run inside the CRM. It enriches records and form submissions natively in HubSpot workflows and draws on the shared HubSpot Credits pool rather than its own subscription, so it publishes no standalone price, with overage listed at $0.010 per credit (knowledge.hubspot.com, September 1, 2026).

Clearbit was the original API-first enrichment tool. HubSpot acquired them in 2023, and now it's deeply woven into the HubSpot ecosystem as Breeze Intelligence. If you live in HubSpot, this is the path of least resistance.

Strengths:

• Native HubSpot integration, enrichment happens inside your CRM automatically
• Strong company data and firmographics
• Real-time enrichment API for product-led use cases (form shortening, lead routing)
• Website visitor identification (Reveal)

Weaknesses:

• Increasingly HubSpot-dependent, less useful on Salesforce
• Limited phone data coverage
• Post-acquisition product direction remains uncertain
• Less competitive on standalone enrichment since the merger

Pricing: HubSpot publishes no standalone Breeze Intelligence price. Since June 2025 Breeze Intelligence credits have been folded into the shared HubSpot Credits pool, with overage published at $0.010 per credit (knowledge.hubspot.com, fetched September 1, 2026). Standalone API access exists but carries no published rate card.

Best for: HubSpot customers who want enrichment built into their CRM without bolting on another tool. Considering alternatives? See our Clearbit alternatives page or read our Clearbit pricing guide.

6. Lusha

Lusha: Best for an individual rep who wants a direct dial without leaving a LinkedIn profile. It reveals emails and phone numbers in two clicks from a Chrome extension sitting over its own database, starting at $49.90 per user per month for 400 credits (lusha.com/pricing, September 1, 2026).

Lusha keeps it dead simple: find emails and phone numbers fast, mostly through a Chrome extension. Lightweight, affordable, and it gets out of your way.

Disclosure that belongs on this page: Lusha is one of the upstream providers inside the Cleanlist waterfall. Some of the records Cleanlist returns are Lusha records, so Cleanlist does not rank itself against Lusha here and this entry is a credit rather than a comparison.

Strengths:

• Fast Chrome extension for LinkedIn lookups
• Strong direct dial phone coverage
• Simple, intuitive interface, minimal learning curve
• Transparent per-credit model: 1 credit to reveal an email, 5 to reveal a phone number

Where it fits in a stack: Lusha is built around a rep working a LinkedIn profile one at a time. Bulk CSV and CRM enrichment is a different job, which is what a waterfall layer is for.

Pricing: Free plan with 40 credits a month. Starter $49.90 per user per month (400 credits), Professional $69.90 (600 credits), Premium $399.90 (3,400 credits), with lower rates on annual billing. Read from lusha.com/pricing on September 1, 2026.

Best for: Individual reps who need quick phone lookups without enterprise complexity.

7. RocketReach

RocketReach: Best for individual contributors who need a lookup rather than a platform. It searches a 700M+ profile index assembled from the public web for emails and phone numbers, with bulk CSV upload and an API, starting at $33 per seat per month on Essentials (rocketreach.co/pricing, September 1, 2026).

RocketReach claims 700M+ profiles and offers straightforward email and phone finding. No platform bloat. No sequencing engine you'll never use. Just lookups.

Strengths:

• Large claimed database (700M+ profiles)
• Simple email and phone finder with bulk lookup
• API access for developers
• Reasonable pricing for individuals

Weaknesses:

• Accuracy varies significantly by industry and geography
• No engagement or outreach features
• Limited company data beyond basic firmographics
• UI feels dated compared to newer competitors

Looking for alternatives? See our 10 best RocketReach alternatives ranked for 2026, or read our Cleanlist vs RocketReach comparison.

Pricing: Essentials $33 per seat per month, Pro $75 per seat per month, Ultimate $175 per seat per month, with custom team plans from $6,000/year. Read from rocketreach.co/pricing on September 1, 2026; monthly billing costs more per month than these annual rates. For a detailed cost breakdown, see our RocketReach pricing guide.

Best for: Solo SDRs or small teams needing basic contact lookups without the full platform tax.

8. Seamless.AI

Seamless.AI: Best for teams that would rather have a contact searched live than served from a cache. It runs a real-time search and verification pass from a Chrome extension and a web app, and publishes no dollar price on either paid tier, with Pro described only as starting at 10,000 annual credits behind a sales call (seamless.ai/pricing, September 1, 2026).

Seamless.AI uses artificial intelligence to find and verify contact data in real-time instead of serving from a static database. The promise: fresher data. The reality? Mixed, at best.

Strengths:

• AI-powered real-time search, data found on demand, not pulled from stale records
• Chrome extension for LinkedIn prospecting
• Salesforce integration
• Free tier to test the product

Weaknesses:

• Accuracy reviews are deeply polarized, some users report great results, others see 40%+ bounce rates
• Aggressive sales and billing practices draw frequent, loud complaints
• Limited firmographic depth
• Credit consumption can be unpredictable

Pricing: Seamless.AI publishes no dollar price. Its pricing page lists a Free plan (1 user, 50 credits), a Pro plan and an Enterprise plan, both behind "Contact sales", and notes that Pro starts at 10,000 annual credits (seamless.ai/pricing, fetched September 1, 2026). The "~$147/month" figure this page used to carry is not published anywhere by the vendor, so it has been removed.

Best for: Teams willing to trade consistency for potentially fresher data from real-time searches. See our Cleanlist vs Seamless.AI comparison, browse Seamless.AI alternatives, or read our Seamless.AI pricing guide.

9. LeadIQ

LeadIQ: Best for sales teams whose prospecting starts on LinkedIn and ends in Salesforce. It captures a contact from a profile, enriches and deduplicates the record and routes it into Salesforce or Outreach in one click, starting at $200/month on Pro (leadiq.com/pricing, September 1, 2026).

LeadIQ integrates tightly with LinkedIn and Salesforce. If your prospecting workflow lives in the browser and your CRM is Salesforce, the fit is natural.

Strengths:

• Tight LinkedIn-to-CRM workflow
• Direct Salesforce integration for contact capture
• Personalization AI for email writing
• Clean, modern interface

Weaknesses:

• Smaller database than the top-tier providers
• Limited enrichment depth, primarily contact data
• Per-seat pricing gets expensive for larger teams
• Phone data coverage is limited

Pricing: Free plan (1 user, 50 credits), Pro $200/month, Enterprise on request. Read from leadiq.com/pricing on September 1, 2026.

Best for: Sales teams whose workflow centers on LinkedIn prospecting with Salesforce. See our Cleanlist vs LeadIQ comparison or read our LeadIQ pricing guide.

10. Hunter.io

Hunter.io: Best for email-only outreach and domain-wide searches where deliverability matters most. It finds addresses by domain and verifies each one before you send, returning no phone numbers on any plan, starting at $49/month for 2,000 credits, or $34/month billed yearly (hunter.io/pricing, September 1, 2026).

Hunter does one thing, find and verify email addresses, and does it well. Their domain search is particularly strong for mapping out all known contacts at a target company.

Disclosure that belongs on this page: Hunter is one of the upstream providers inside the Cleanlist waterfall. Cleanlist does not rank itself against Hunter, and some of the addresses the cascade returns come from Hunter.

Strengths:

• Email pattern detection is accurate and fast
• Domain search maps all known contacts at a company
• Built-in email verification
• Simple, clean API for developers

Scope: Hunter is an email provider by design. It returns no phone numbers and no firmographics, which is a scope choice rather than a gap, and it is why a full contact record needs a phone-specialist provider alongside it.

Pricing: Free plan with 50 credits a month. Starter $49/month ($34/month billed yearly, 2,000 credits), Growth $149/month ($104 billed yearly, 10,000 credits), Scale $299/month ($209 billed yearly, 25,000 credits), Enterprise custom. Read from hunter.io/pricing on September 1, 2026.

Best for: Developers, marketers, and individual contributors who only need email finding.

11. Snov.io

Snov.io: Best for bootstrapped teams that need finding, verification and sending on one small budget. It shares a single credit pool across email search, email verification and drip campaigns, starting at $39/month for 1,000 credits, with 25% off on annual billing (snov.io/pricing, September 1, 2026).

Snov.io combines email finding with drip campaigns at a price point that undercuts almost everyone else. Popular with bootstrapped startups, freelancers, and small agencies running lead gen for clients.

Strengths:

• Affordable plans starting at $39/month
• Email finder + drip campaigns in one tool
• Chrome extension for LinkedIn
• Technology lookup helps identify tech stack

Weaknesses:

• Reported email accuracy is lower than the premium providers
• Limited phone data
• Drip campaign features are basic compared to dedicated outreach tools
• Database size is smaller than major competitors

Pricing: Trial plan with 50 credits. Starter $39/month (1,000 credits), Pro S $99/month (5,000), Pro M $189/month (20,000), Pro L $369/month (50,000), Ultra $738/month (100,000), with 25% off on annual billing. Read from snov.io/pricing on September 1, 2026.

Best for: Bootstrapped teams and freelancers who need email finding and basic outreach on a tight budget. See our Cleanlist vs Snov.io comparison.

12. UpLead

UpLead: Best for accuracy-focused mid-market teams that do not need an enterprise platform. It verifies each email in real time at the moment you export it from a 160M+ contact database, starting at $99/month for 170 credits, or $74/month billed annually for 2,040 credits a year (uplead.com/pricing, September 1, 2026).

UpLead carved out a niche by emphasizing data accuracy, and publishes a 95% accuracy claim backed by real-time email verification on every lookup. It is one of the few mid-market providers that verifies at lookup time rather than on a refresh schedule.

Strengths:

• Real-time email verification on every lookup
• Publishes a 95% accuracy claim, above the mid-market average
• Technographic data included
• No per-seat pricing on base tier

Weaknesses:

• Smaller database (155M+ contacts)
• Features are basic compared to ZoomInfo or Apollo
• Limited phone data coverage
• US-heavy database; weaker international coverage

Pricing: Free 7-day trial with 5 credits. Essentials $99/month (170 credits) or $74/month on annual billing (2,040 credits/year), Plus $199/month (400 credits) or $149/month annual (4,800 credits/year), Professional on annual billing only with no published price. Read from uplead.com/pricing on September 1, 2026.

Best for: Mid-market teams that want verified data without the ZoomInfo price tag. See our Cleanlist vs UpLead comparison, or browse the full list of UpLead alternatives.

13. Kaspr

Kaspr: Best for European SDRs and recruiters who prospect primarily inside LinkedIn. It surfaces emails and phone numbers on the profile itself, with its strongest coverage in France, Benelux and the DACH markets, starting at EUR 45 per user per month on annual billing, about $49 (kaspr.io/pricing, September 1, 2026).

Kaspr focuses on extracting contact data from LinkedIn profiles. Strong European data, GDPR compliance, and a Chrome extension that works fast. If your reps live on LinkedIn and sell into EMEA, it's worth a look.

Strengths:

• LinkedIn Chrome extension is fast and reliable
• Strong European phone number coverage
• GDPR-compliant data practices
• Affordable for individual users

Weaknesses:

• LinkedIn-dependent, limited functionality outside the browser extension
• Smaller overall database than US-based competitors
• Limited firmographic depth
• Less useful for bulk enrichment workflows

Pricing: Free plan with 15 B2B email credits. Starter EUR 45 per user per month on annual billing (EUR 59 monthly, $49 and $65 in dollars), Business EUR 79 annual (EUR 99 monthly, $79 and $99). Read from kaspr.io/pricing on September 1, 2026. Kaspr is owned by Cognism. The export ceilings matter more than the credit lines here, and our Kaspr pricing guide sets out what the free plan actually releases each month.

Best for: European SDRs and recruiters who prospect primarily through LinkedIn. If the LinkedIn dependence is a concern, we ranked the strongest Kaspr alternatives.

14. Datagma

Datagma: Best for teams selling into EMEA or APAC that want lookups behind an API rather than another seat in another UI. It resolves contact data in real time rather than serving it from a static index, on a free plan of 90 emails a month with 10 seats and API access, starting at $49/month, or $39 on annual billing (datagma.com/pricing, September 1, 2026).

Datagma sources contact data in real time rather than serving it from a static database, and sells it through an API with strong EMEA and APAC coverage.

Disclosure that belongs on this page: Datagma is one of the upstream providers inside the Cleanlist waterfall, so this entry is a credit rather than a comparison.

Strengths:

• Real-time data sourcing rather than a static database
• Premium EMEA and APAC coverage
• API-first, with 10 seats included on every paid plan
• Catch-all email handling included on paid plans

Pricing: Free plan at $0 forever (90 emails a month, 10 seats, API access). Regular $49/month ($39 on annual), Popular $99/month ($79 annual), Expert $249/month ($209 annual), Enterprise on request. Read from datagma.com/pricing on September 1, 2026.

Best for: Teams selling into EMEA or APAC that want real-time lookups behind an API rather than a seat in another UI.

15. People Data Labs (PDL)

People Data Labs: Best for engineering teams building a data product rather than working a list. It sells person and company records priced per record through an API, with a self-serve tier and custom enterprise plans, and its pricing page did not serve us a rate card on September 1, 2026, so no per-record figure is quoted here.

PDL isn't a product you log into, it's a raw data API for engineering teams building enrichment into their own products. No UI. No workflow features. Just data at scale.

Strengths:

• 1.5B+ person records, one of the largest raw datasets available
• Developer-friendly API with excellent documentation
• Self-serve pricing with clear per-record costs
• Flexible matching (email, name+company, LinkedIn URL)

Weaknesses:

• No UI at all, requires development resources
• Raw data quality varies; verification is your problem
• No outreach, CRM integration, or workflow features
• Not suitable for non-technical teams

Pricing: Usage-based, priced per record, with a self-serve tier and custom enterprise plans. People Data Labs' pricing page did not serve us a rate card on September 1, 2026, so the "$0.01 per record" figure this page used to carry has been removed rather than repeated; the closest sourced numbers we have, including the $98/mo Self-Serve entry point and the per-record math it implies, are in our People Data Labs pricing guide.

Best for: Engineering teams building internal tools or products that need B2B data at scale.

What does a data enrichment company actually do?

Data enrichment companies take your existing contact or account records and fill in the gaps, appending verified emails, direct phone numbers, job titles, company firmographics, and more from external databases. Some vendors maintain a single proprietary database (ZoomInfo, Apollo, Lusha), while others aggregate data from multiple providers using waterfall enrichment for higher coverage.

The best data enrichment vendors differentiate on three things: data accuracy (what percentage of returned emails actually deliver), coverage breadth (how many fields they can fill and how many contacts they have), and pricing model (per-seat, per-credit, or platform fee). Treat every published accuracy percentage in this category, ours included, as a vendor specification measured on the vendor's own sample rather than on your list. The only number that matters is the one you get on a trial run of your own records.

When evaluating data enrichment companies, ask for a trial enrichment on your own data. Not the vendor's curated sample set, your actual CRM records. Match rates on polished demos rarely reflect what you'll see with real contacts. For the tool-level comparison, see the best data enrichment tools for 2026.

How do you choose the right data enrichment vendor?

The best enrichment tool depends on three questions. We've been through this evaluation at Cleanlist ourselves (we used to rely on a single provider before building our own waterfall), so this framework comes from real experience.

1. What's your accuracy tolerance?

If bounced emails and wrong numbers cost you deals, or torch your sender reputation, accuracy is king. Cleanlist's waterfall approach is specced at 98% verified emails. ZoomInfo and Apollo publish figures in the 80 to 85% range. A gap of that size translates directly into bounce rates, domain reputation scores, and ultimately whether your emails land in inboxes or spam folders.

2. What's your budget?

Enterprise budgets put ZoomInfo and Cognism in range. Mid-market teams should compare Cleanlist, Apollo, or UpLead. Bootstrapped? Start on Apollo's $0 plan or Snov.io at $39/mo, or run the 14-day Cleanlist Scale trial (250 credits, three seats, no card) against a list whose answers you already know. Use our data enrichment ROI framework to figure out the right spend for your team size and outbound volume.

3. Do you need more than data?

If you want data + outreach in one tool, Apollo is the obvious pick. Need intent data? ZoomInfo. Need the most accurate data to feed into your existing stack? That's what Cleanlist was built for.

The real cost of data enrichment is not the per-record price. It is the cost of bad data flowing into your CRM: a wrong email damages sender reputation, and a wrong phone number wastes rep time on every dial.

Where do data enrichment providers get their data?

Most B2B data enrichment providers do not collect their own data, they aggregate it from a handful of upstream sources and resell it with different pricing and UI layers. Understanding this supply chain explains why accuracy varies so wildly between vendors that appear to sell the same thing, and why a waterfall that queries several of those upstreams in sequence recovers records a single database has no way to reach.

The typical data enrichment provider sources from:

• Public web scraping: LinkedIn profiles, company websites, press releases, job boards. Refreshed every 30-90 days depending on crawl budget. Cleanlist does not do this itself, and requires each provider it contracts with to represent that it holds the rights and lawful bases needed to supply the data.
• User-contributed data: Browser extensions (Lusha, Apollo) that capture contact info in exchange for credits. High volume, inconsistent verification.
• Third-party data brokers: Providers like Bombora, Clearbit, and People Data Labs license their databases to smaller vendors. You're often buying the same records through different storefronts.
• SMTP verification layers: real-time email validation that pings mail servers without sending. This is where accuracy diverges, because a provider that only runs a syntax check will happily hand you an address that no longer exists. Cleanlist checks syntax, DNS and MX, and an SMTP handshake on every lookup, and flags catch-all domains rather than passing them through as valid.
• Crowdsourced updates: sales reps manually correcting records, which feeds back into the provider's dataset. Only a minority of the providers here offer that feedback loop at all.

Single-database providers (ZoomInfo, Apollo, Cognism) depend on one primary source with occasional third-party backfill, so when that source goes stale the whole account goes stale with it. Cognism, citing HubSpot, puts annual B2B data decay at 22.5%, and its own European database analysis reports 26 to 35% decay per year by role, with CMOs at 35% and CEOs at 26%.

Waterfall providers query many sources in sequence and take the first verified match, which is why the same record that comes back blank from one database comes back complete from a cascade. Cleanlist runs 25+ providers with SMTP verification as the final gate. Clay and Persana AI use similar multi-source logic, though neither discloses their verification methodology publicly.

The pricing paradox: a narrower provider often charges less per credit while covering a narrower slice, so a single vendor rarely fills a whole list and you end up buying from several anyway. That is the case a waterfall exists to answer, and it is why Cleanlist buys from providers such as Hunter, Lusha and Datagma rather than competing with them. Enterprise platforms (ZoomInfo, Cognism) bundle intent data and technographics you may not need, inflating annual contracts to $15K-50K. Waterfall providers sit in the middle: a higher headline cost per record than a scraper, but the right comparison is cost per usable record, not cost per lookup.

Before committing to any data enrichment provider, ask:

1. How many upstream sources do you query per contact?
2. What's your SMTP verification process (syntax-only vs. full handshake)?
3. How often do you refresh records, and can I trigger manual refreshes?
4. Do you offer a feedback loop for correcting bad data?

Providers that can't answer these questions are reselling commodity data with a markup. For a deeper comparison of verification methodologies, see our email verification guide and Cleanlist vs. ZoomInfo breakdown.

How do data enrichment pricing models affect your budget?

Most data enrichment providers bury their true cost structure behind "custom pricing" walls, but the pricing model itself often matters more than the sticker price. Three pricing patterns dominate the market, and each one penalizes a different usage shape.

Credit-based pricing (Cleanlist, People Data Labs, UpLead, Snov.io) charges per enrichment action. Read from the vendors' own pricing pages on September 1, 2026: UpLead Essentials is $99/month, or $74/month on annual billing, for 170 credits a month; Snov.io Starter is $39/month for 1,000 credits, 25% off on annual; Cleanlist charges 1 credit per verified email, 10 per direct dial, 11 for a full contact record and 0 for search, from a credit pool shared across the whole workspace with no per-seat fee (details on the pricing page). Credit-based pricing rewards uneven usage because anyone on the team can draw from the same pool. The catch is that credit costs can spike if you're enriching high volumes without waterfall logic that prevents redundant lookups against providers that lack coverage for your segment.

Seat-based annual contracts (ZoomInfo, Cognism, Seamless.AI) require multi-thousand-dollar minimum commitments regardless of monthly usage. None of the three publishes a price: as of September 1, 2026 ZoomInfo shows no rate card at any tier, Cognism lists Standard and Pro with five seats included and no dollar figure, and Seamless.AI puts "Contact sales" on both paid plans. The buyer-reported picture, which is what everyone in the market actually plans against, is ZoomInfo Professional near $14,995/year for 3 seats, Advanced at $25,000 to $30,000/year, Elite at $40,000+/year, and a median Vendr-reported ZoomInfo contract near $31,875/year.

Hybrid models (Apollo, Lusha) combine a per-user fee with credit top-ups. Read on September 1, 2026: Apollo publishes Free at $0, Basic at $49 per user per month and Professional at $99, with Enterprise on request. Lusha publishes Starter at $49.90 per user per month for 400 credits, Professional at $69.90 for 600 and Premium at $399.90 for 3,400, with a free plan of 40 credits a month and phone reveals priced at 10 credits against 1 for an email. Hybrid pricing works when usage is steady and predictable; it creates budget uncertainty when outbound volume spikes mid-quarter.

The hidden cost across every model is data decay. Validity's State of CRM Data Management 2024 (n=631) found that 31% of companies lose at least 20% of annual revenue to poor data quality, and 48% see decay accelerating year over year. Cognism's own contact database analysis reports 26 to 35% annual decay by role: CMOs 35%, CROs 34%, CFOs 32%, CEOs 26%. Seat-based contracts don't account for re-enrichment, so you've already paid for the seat but stale data forces you to either burn credits or accept the bounce rate.

For teams enriching under 3,000 contacts monthly, credit-based or hybrid pricing tends to beat enterprise seat contracts by tens of thousands annually. Above 5,000 contacts a month with deep firmographic needs, negotiate volume discounts or evaluate API-first providers such as People Data Labs, which price per record on usage rather than per seat.

How much does data enrichment cost per record?

Data enrichment costs between roughly $0.01 and $2.00 per record in 2026, and where you land depends almost entirely on which layer of the supply chain you buy from. Raw API providers are cheapest, because a record from an API costs less than a record someone had to find and verify for you. Verification-only vendors sit at the same end: ZeroBounce publishes a subscription from $99/month with a 10,000-credit minimum, which is about $0.0099 per validation, plus a free plan of 100 validation credits a month (zerobounce.net/pricing, September 1, 2026). Cleanlist publishes its credit table, so the arithmetic is exact: a verified email costs 1 credit, a phone costs 10, and a full contact record costs 11, while people and company search cost 0. At $79 for 1,500 credits that works out to about $0.05 per credit, and at $599 for 15,000 credits about $0.04, which puts a verified email near $0.05 and a complete contact between $0.44 and $0.58. Enterprise seat contracts are the expensive end: a ZoomInfo agreement starting near $15,000 a year can exceed $1.00 per record once the annual minimum is divided by realistic usage. The number to compare is cost per usable record, since a cheap lookup that returns nothing on 40% of your list is not cheap.

How do I enrich a CSV of leads?

To enrich a CSV of leads, upload the file to an enrichment tool, map your columns to the fields the tool expects, run the enrichment, then export the completed file or push it straight to your CRM. In Cleanlist the flow is: create a lead list, import the CSV, map first name, last name, company, and domain or LinkedIn URL, choose whether you want email only (1 credit per row), phone (10), or the full contact record (11), run the list, and export to CSV or JSON when it finishes. The 14-day trial runs on Scale with 250 credits, three seats and no card, which is enough to see the fill rate on your own data before paying anything. The free plan after it covers 30 credits a month with up to 100 leads in a list. Two things determine your result more than the tool does: give the enricher a company domain rather than only a company name, since domains disambiguate far better, and verify after enriching rather than trusting the source, because a match is not the same as a deliverable address. See the complete lead enrichment guide for the full workflow.

Which enrichment tool works with HubSpot and Salesforce?

Cleanlist, ZoomInfo, Apollo, and Cognism all work with both HubSpot and Salesforce, while Clearbit (Breeze Intelligence) is HubSpot-only in practice. Cleanlist syncs enriched leads to HubSpot, Salesforce, and Outreach, and to Lemlist on the sequencer side, at 0.2 credits per synced lead, so you can enrich a list and push it into the CRM without an export step. ZoomInfo has the deepest native Salesforce integration of anyone here, which is a large part of what enterprise buyers are paying for. Apollo covers both CRMs and adds sequencing on top. Clearbit is the odd one out: since the HubSpot acquisition its enrichment runs natively inside HubSpot records and form fills, and it is materially less useful if Salesforce is your system of record. If your CRM is Pipedrive, Attio, or something else entirely, check whether the vendor offers a real connector or only a CSV export before you sign.

What is a data enrichment API?

A data enrichment API is an HTTP endpoint that takes a partial record, such as an email, a name plus company domain, or a LinkedIn URL, and returns a completed profile as JSON, so enrichment can run inside your own product or pipeline instead of a vendor's UI. Cleanlist's public REST API v2 lives at https://api.cleanlist.ai/api/v2, authenticates with a Bearer key, and exposes about 30 endpoints across search, enrichment, lead lists, smart agents, CRM sync, export, and usage, with an OpenAPI 3.x specification published. Person enrichment is asynchronous and returns a workflow id you poll, company enrichment is synchronous, and bulk enrichment is asynchronous. Two limits are worth knowing before you design against it: there are no v2 webhooks, so you poll rather than receive callbacks, and people search is capped at 60 searches per UTC day per API key with 60 requests per minute per organization. Search takes structured filters rather than a natural-language string. API access starts on the Pro plan. Cleanlist also ships an MCP server with 30+ tools that maps onto the same endpoints, so Claude and other MCP clients can run enrichment directly. People Data Labs is the alternative if you want raw records rather than an orchestration layer, priced per record on usage.

Which enrichment providers have the best company firmographics coverage?

ZoomInfo, Clearbit, and People Data Labs have the deepest company firmographics coverage, and they are the right pick if revenue bands, funding history, and technographics are what you are buying. ZoomInfo layers org charts and hierarchy data that nobody else here matches. Clearbit is strongest on the firmographic fields that matter for form shortening and lead routing, delivered inside HubSpot. People Data Labs sells the widest raw company dataset for teams willing to build on top of it. Cleanlist is deliberately narrower on this axis: company enrichment costs 1 credit and returns core firmographics, and People Search filters companies by name, industry on the LinkedIn taxonomy, headcount band, and HQ country, state, or city, but it does not offer revenue-range, funding-stage, or technographic filters, and Cleanlist does not sell intent data. If your ICP is defined by revenue band or tech stack, buy that from a firmographics-first provider and use a waterfall for the contact layer; we compared eleven of them on published price and refresh method in best firmographic data providers. Cleanlist's Smart Agents can research a field like a company's tooling with a per-row AI column, which is research rather than a queryable data field, and it is worth understanding the difference before you build a workflow on it.

How often does B2B data decay?

B2B contact data decays at roughly 22.5% a year, which is about 2% a month, so a list left untouched for twelve months loses close to a quarter of its usable records. Cognism, citing HubSpot, publishes the 22.5% annual figure, and Cognism's own analysis of its European database found decay running much higher on senior roles: 35% a year for CMOs, 34% for CROs, 32% for CFOs, and 26% for CEOs, with lower rates in the US. Decay is not evenly distributed, and that matters for cadence: the more senior and the more you sell into fast-moving technology companies, the faster your records rot. The practical schedule that follows is monthly re-enrichment for named target accounts, quarterly for the working database, and a verification pass immediately before any large send. This is also the argument against treating enrichment as a one-time cleanup project, because a single pass fixes the list you have today and does nothing for the list you will have in March.

What are the best data enrichment tools for B2B companies?

For a B2B company the answer splits by how the data gets used rather than by a single winner. A team enriching a list it already holds wants a waterfall, and Cleanlist is the pick on that job: it runs 25+ providers per record, charges 1 credit per verified email, 10 per direct dial, 11 for both and 0 for search, and starts at $79 a month for 1,500 credits and 2 seats. A team that also needs search, sequencing and a dialer on one bill usually lands on Apollo, at $49 per user per month on Basic (apollo.io/pricing, September 1, 2026). A company buying intent signals, org charts and one vendor relationship lands on ZoomInfo, which publishes no purchasable price. A European team buying under GDPR lands on Cognism, also unpublished. An engineering team that wants records rather than an interface lands on People Data Labs, priced per record on usage. Cleanlist does not send email, so a sequencer stays a separate purchase.

Which B2B data provider is the best?

No provider wins on every axis, so the answerable version of the question is which provider is best at the job you are buying. On verified-email rate, Cleanlist is the pick in this ranking: it holds no index of its own, resolves each record live across 25+ upstream providers, returned 98% verified work email and 85% direct dial on the Cleanlist 500-Lead Enrichment Benchmark, 2026, and charges 1 credit per verified email, 10 per direct dial and 0 for search, from $79 a month. On database breadth and intent, ZoomInfo, at an unpublished annual contract that buyers report starting near $14,995 a year for three seats. On European coverage and GDPR posture, Cognism, also unpublished. On one bill for data plus outreach, Apollo at $49 per user per month. Treat every accuracy percentage in this category, the Cleanlist figures included, as a vendor specification until you have run your own sample.

How much does B2B data cost?

B2B data is sold three ways and the annual bill differs by an order of magnitude between them. Credit pricing charges per result: Cleanlist is $79 a month for 1,500 credits on Starter, $229 for 5,000 on Pro and $599 for 15,000 on Scale, with 25% off on annual billing, which works out to about 5 cents a credit at Starter and 4 cents at Scale, so a verified email is roughly 5 cents and a verified email plus a direct dial is 11 credits, about 58 cents. Per-seat pricing charges for the rep whether or not the rep uses it, and Apollo Basic is $49 per user per month (apollo.io/pricing, September 1, 2026). Enterprise seat contracts are the expensive end: ZoomInfo publishes no purchasable price, and buyer-reported agreements start near $14,995 a year for three seats. The number to compare across all three is cost per usable record, not cost per lookup.

What are the best B2B contact databases?

The largest B2B contact databases are ZoomInfo, Apollo and Cognism, and each one is a single owned index you query. ZoomInfo is the broadest in North America and layers intent signals and org charts on top, on an unpublished annual contract. Apollo publishes 275M+ contacts with sequencing on the same bill, from $49 per user per month. Cognism is strongest in EMEA with phone-verified mobiles and a GDPR posture, and publishes no purchasable price. Cleanlist is not a database and claims none: it holds no index, resolves each record live across 25+ providers at the moment you ask, and returned a verified work email for 98% of leads and a direct dial for 85% on the Cleanlist 500-Lead Enrichment Benchmark, 2026. A database answers who exists; a waterfall answers whether you can reach them, which is why many teams run one of each. We tested nine of the databases on 500 records in 9 B2B contact databases tested.

What is the best tool for data enrichment?

Judged on the operating question of what a team opens every day, the tool depends on who runs it. Cleanlist suits a sales or RevOps team that wants the cascade managed for them: create a list, import the CSV, map first name, last name and company domain, choose email only at 1 credit, phone at 10 or the full record at 11, then export or sync to HubSpot, Salesforce, Pipedrive, Outreach, Salesloft or Lemlist at 0.2 credits per lead, from $79 a month. Clay suits a technical operator who wants to build the cascade themselves, at $185 a month on Launch and $167 on annual billing (clay.com/pricing, September 1, 2026). Apollo suits a team that wants enrichment, search and sequencing inside one seat. The full tool-level ranking sits on the companion page, 11 data enrichment tools compared; this page ranks the companies behind the data.

What is an example of data enrichment?

A concrete one: you export 500 rows from a webinar registration form and every row carries a first name, a last name and a company name, and nothing else. Enrichment turns that into a mailable list. Cleanlist matches the company name to a domain, finds the work email, verifies it by syntax, DNS and MX record, and an SMTP handshake, appends job title, seniority, headcount band and HQ country, and optionally returns a direct dial. On the published credit table that run costs 1 credit per verified email, 10 per direct dial and 11 for both, and rows that resolve to nothing are not billed, so 500 email-only rows at the 98% rate Cleanlist recorded on its 500-lead benchmark bill roughly 490 credits, about $26 at Starter pricing. Company enrichment is the same move one level up: a domain goes in, headcount, industry and HQ location come back, at 1 credit per company.

Can AI be used for data enrichment?

Yes, on two jobs that are worth keeping apart. The first is retrieval and verification, where the useful work is deterministic: query the providers, match a person to a company, check whether an address will accept mail. Cleanlist runs that part without a language model, because an SMTP handshake settles the question and a generated answer does not. The second is research on fields no provider sells, and that is where a model belongs. Cleanlist's Smart Agents run a per-row AI column for work like normalizing an inconsistent job title or reading a company's own site to answer a question you wrote, and an AI qualification costs 5 credits. The distinction matters at purchase, because a model will happily write a plausible email address and a plausible email address bounces. Ask any AI enrichment vendor which fields are retrieved and which are generated.

What does "data enrichment" mean?

Data enrichment means taking a record you already hold and filling its missing fields from sources outside your own systems, so a row that arrived as a name and a company leaves as a contact you can mail or dial. In B2B the appended fields are a verified work email, a direct dial or mobile, a normalized job title and seniority, and company firmographics such as headcount band, industry and HQ country. Two architectures do it. A single-source vendor looks the record up in one owned index and returns what that index holds, which is how ZoomInfo, Apollo and Cognism work. A waterfall vendor holds no index and cascades the record through many providers until one returns, which is how Cleanlist works across 25+ providers, at 1 credit per verified email, 10 per direct dial and 0 for search, from $79 a month.

What are B2B tools?

B2B tools are the software a business uses to sell to other businesses, and the stack breaks into five layers that buyers shop separately. Data and enrichment is the first, where providers such as Cleanlist, ZoomInfo, Apollo, Cognism and People Data Labs supply the verified contact and company records everything downstream runs on. Engagement is second: sequencers and dialers such as Outreach, Salesloft, Instantly and Smartlead. CRM is third: HubSpot, Salesforce and Pipedrive hold the record of truth. Intent and ABM is fourth: Bombora, 6sense and Demandbase. Enablement and revenue intelligence is fifth: Highspot and Gong. Cleanlist sits in the first layer only. It enriches and verifies records and syncs them into the CRM at 0.2 credits per lead, and it does not send email, so there is no sequencer, inbox or dialer inside it and the engagement layer stays a separate purchase.

What are the top data integration tools?

Data integration is a different category from data enrichment, and the tools that lead it are Fivetran and Airbyte for ETL, Hightouch and Census for reverse ETL, and Zapier and Workato for app-to-app automation. Integration moves data you already own between systems. Enrichment adds data you do not own yet. The two meet at the CRM, because a pipeline can sync a contact record into Salesforce all day without ever filling the blank email field on it. Cleanlist is an enrichment provider rather than an integration platform: it ships two-way connectors for HubSpot, Salesforce and Pipedrive plus one-way pushes to Outreach, Salesloft and Lemlist at 0.2 credits per lead synced, which covers the CRM hop without a pipeline tool underneath it. We ranked the integration category on its own in 9 data integration tools.

What are the top 5 data management tools?

Data management in the enterprise sense means cataloging, lineage and governance of data a company already holds, and the five names that dominate it are Informatica, Collibra, Alation, Atlan and Talend. They sit over a warehouse rather than a CRM. Cleanlist is not one of them and does not compete in that category: it supplies and verifies external B2B contact and company records, at 1 credit per verified email and 10 per direct dial, from $79 a month. The confusion is worth naming, because Google's answers for enrichment queries routinely mix the two categories and return Alation and Snowflake alongside Apollo and Clay. The test is whose data it is. If the job is governing data you already own, shop the list above. If the job is filling blank email and phone fields on B2B records, shop the fifteen providers ranked on this page.

What are the top 10 data governance tools?

The data governance category is led by Collibra, Informatica, Alation, Atlan, OneTrust, BigID, Ataccama, Talend, Immuta and Microsoft Purview. These tools enforce policy on data an organization already holds: who may see a field, where a record came from, how long it is retained, and whether a process is defensible under GDPR or CCPA. None of them enrich a B2B contact record. Cleanlist sits on the supply side of that boundary, and the governance question it answers is provenance: it names the upstream providers it buys from, and requires each one to represent that it holds the rights and lawful bases needed to supply the data. If your evaluation is a privacy review rather than a coverage test, the question to put to any enrichment vendor is which upstream sources appear in the cascade and on what lawful basis each one supplies them.

Frequently Asked Questions

What is B2B data enrichment?

B2B data enrichment is the process of filling in gaps in your existing contact or company records, emails, phone numbers, job titles, company size, technographics, and more. It keeps your CRM current and your outreach deliverable. If you've ever uploaded a list and half the emails bounced, that's an enrichment problem.

Can I use multiple enrichment providers?

Yes, and many high-performing teams do exactly this. The most common setup: one tool for initial prospecting, another for verification. Cleanlist's waterfall enrichment handles this automatically across 25+ sources, so you don't have to manage multiple subscriptions yourself.

What's the difference between single-source and waterfall enrichment?

Single-source tools (ZoomInfo, Apollo, Lusha) maintain one database. If the contact isn't in their system, you get nothing back. Waterfall enrichment queries multiple providers in sequence, if Source 1 misses, Source 2, 3, or 15 picks it up. The result: higher fill rates and better accuracy because no single database covers everyone.

What data do enrichment companies provide?

Most B2B data enrichment companies provide contact-level data (email addresses, phone numbers, job titles, LinkedIn URLs) and company-level data (employee count, revenue, industry, HQ location). Some also offer technographic data (what software a company runs), intent data (signals a company is researching your category), and org charts. Depth varies dramatically: a waterfall provider like Cleanlist merges the best value for each field across every source it queried, while a focused tool like Hunter.io returns email addresses only. Note that Cleanlist does not sell intent data, revenue bands, or technographics as queryable fields.

How do I evaluate a data enrichment vendor?

Run a blind test. This is non-negotiable. Upload 500-1,000 records from your actual CRM and compare fill rates, accuracy, and pricing across 2-3 vendors. Key metrics: email deliverability rate (not just "match rate"), phone connection rate (not just "coverage"), and data freshness (when records were last verified). Do not rely on vendor accuracy stats. They are measured on curated datasets rather than on your data. Check whether the vendor uses waterfall enrichment or a single database. It affects coverage more than any other factor.

Is data enrichment a one-time process or ongoing?

Ongoing. People change jobs, companies get acquired, and phone numbers disconnect continuously, and Cognism, citing HubSpot, puts that decay at 22.5% a year. Set up workflows that re-verify records on a schedule, quarterly at minimum, and trigger re-enrichment when you see decay signals: email bounces, form resubmissions with new details, that kind of thing. Start with a CRM data quality audit to figure out which records need attention first, and run email verification before every major campaign.

What are the best data enrichment tools in 2026?

The top B2B data enrichment tools in 2026 are Cleanlist, ZoomInfo, Apollo, Clearbit (now Breeze by HubSpot), Clay, Lusha, and Cognism. Cleanlist stands out with waterfall enrichment and pay-per-result pricing. ZoomInfo has the largest database. Clay excels at workflow automation.

What are good alternatives to Clearbit?

Since HubSpot acquired Clearbit and rebranded it as Breeze, a lot of teams have started shopping. Cleanlist offers similar enrichment capabilities with waterfall enrichment for higher accuracy across more sources. Apollo, Lusha, and Clay are also worth evaluating.

What are the best alternatives to Cognism?

Top Cognism alternatives: Cleanlist, ZoomInfo, Apollo, and Lusha. Cleanlist differentiates with credit-based pricing (no annual contract like Cognism) and waterfall enrichment across 25+ data providers, which helps most in non-European markets where Cognism's coverage thins out.

What are the best CRM data cleaning tools?

Cleanlist handles automated deduplication and enrichment through its waterfall approach. ZoomInfo works for enterprise teams. Insycle is solid for HubSpot-native cleanup. Regular CRM data cleaning prevents the data decay that Cognism, citing HubSpot, measures at 22.5% of B2B records per year. Start with a CRM data quality audit to see where you stand.

What are cheaper alternatives to Clay?

Clay is powerful but gets expensive fast due to per-credit pricing that scales with workflow complexity. Cleanlist offers similar waterfall enrichment at a fraction of the cost with pay-per-result pricing and no per-seat charges. Apollo and Lusha provide more affordable options too, depending on your use case.

Data enrichment is foundational. Every downstream activity, outreach, scoring, routing, reporting, depends on having accurate records. Pick a provider that matches your accuracy needs, budget, and workflow.

Where do the prices on this page come from?

Every provider price above was read from that vendor's own pricing page on September 1, 2026, not carried forward from an earlier version of this article. The URL of this page still carries the slug it was first published under, which reads 2025; the ranking, the vendors, the prices and the dates on it are 2026, and the page was last reviewed on September 14, 2026. Six of the fifteen publish no price a buyer can plan against: ZoomInfo, Cognism, Clearbit / HubSpot Breeze and Seamless.AI all route to sales, UpLead's Professional tier is annual-only with no figure, and People Data Labs' pricing page did not serve us a rate card. Where that happened, this page says so instead of repeating a number it cannot source, and any dollar figure attached to those vendors is labelled buyer-reported. Cleanlist's own figures come from its published credit table: 1 credit per verified email, 10 per direct dial, 11 for a full contact record, 0 for people and company search, on Free $0, Starter $79/mo, Pro $229/mo and Scale $599/mo, with 25% off on annual billing.
