15 Best B2B Data Enrichment Providers in 2025, Ranked

B2B data enrichment has become table stakes. Every sales and marketing team needs accurate contact data, firmographics, and technographics to hit their numbers.

But the market is crowded. Over 50 vendors sell some version of "B2B data." Most use the same underlying sources, slap a different UI on top, and charge wildly different prices for similar results.

We tested and ranked 15 providers based on five criteria that actually matter: accuracy, coverage, pricing transparency, integrations, and ease of use. No vendor paid for placement. No affiliate links.

How We Ranked These Providers

Each tool was evaluated across five weighted categories:

• Accuracy (30%): Email deliverability rates and phone connection rates from real-world testing
• Coverage (25%): Database size, fill rates for key fields (email, phone, title, company data)
• Pricing (20%): Cost per enrichment, pricing transparency, minimum commitments
• Integrations (15%): CRM connectors, API quality, workflow compatibility
• Ease of use (10%): Time to value, interface quality, learning curve

We ran 1,000 contact enrichments through each platform and measured actual deliverability - not the accuracy numbers vendors claim on their websites.

The Top 5 at a Glance

1. Cleanlist

Best for: Teams that need verified, accurate data without overpaying

Cleanlist doesn't maintain a single database. Instead, it uses waterfall enrichment to query 15+ premium data sources for every lookup. If Provider 1 doesn't have the email, it tries Provider 2, then Provider 3 - up to 15+ sources deep.

The result: higher fill rates than any single-source tool, with every email verified before it's returned.

What sets it apart:

• Waterfall enrichment: 15+ data sources queried per lookup. No single point of failure for coverage gaps.
• 98% email accuracy: Every email is verified in real-time. Not periodically - on every single lookup.
• People Search: Access 500M+ professional profiles. Search by natural language or 30+ filters to build targeted lead lists from scratch.
• ICP Scoring: Score every lead against your Ideal Customer Profile automatically.
• Smart Columns: Normalize job titles, format phone numbers, and transform messy data without manual cleanup.
• Credit-based pricing: Pay for what you use. No annual contracts required. No per-seat fees.

Strengths:

• Highest accuracy in our testing (98% email deliverability)
• Flexible pricing works for teams of 1 or 100
• People Search lets you build lists from zero - no existing data needed
• Data transformation features clean records automatically

Weaknesses:

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

Pricing: Credit-based. Email-only enrichment starts at 1 credit. Full enrichment (email + phone + firmographics) costs 11 credits. People Search exports cost 20 credits per 100 contacts. Volume discounts available. See pricing.

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

2. ZoomInfo

Best for: Enterprise companies that need intent data and a single vendor

ZoomInfo is the market leader for a reason. It has the largest proprietary B2B database, the most mature intent data product, and the brand recognition that makes procurement teams comfortable.

But that comes with enterprise pricing and enterprise complexity.

Strengths:

• 300M+ contacts, 100M+ company profiles - the largest 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
• Single-source database means unavoidable data decay and gaps
• Opaque pricing requires talking to sales before budgeting

Pricing: SalesOS Professional starts ~$15,000/year. Advanced ~$25,000/year. Elite (with intent) ~$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.

3. Apollo

Best for: Startups and SMBs wanting data + outreach in one tool

Apollo grew fast by combining a large contact database with email sequences, a dialer, and a Chrome extension - all at a price point startups can afford. It's the "good enough at everything" option.

Strengths:

• All-in-one: data + sequences + dialer, no need to integrate multiple tools
• Free tier with 100 credits/month to test before committing
• Clean interface with fast time to value

Weaknesses:

• Lower email accuracy (~80%) leads to higher bounce rates
• Limited direct dial phone coverage compared to ZoomInfo or Cleanlist

Pricing: Free (100 credits/month), Basic $59/user/month, Professional $99/user/month, Organization $149/user/month.

Best for: Early-stage teams with limited budget who want one tool for prospecting and outreach.

4. Cognism

• Intent data through Bombora partnership

Weaknesses:

Choosing the Right Provider

The best enrichment tool depends on three questions:

1. What's your accuracy tolerance?

If bounced emails and wrong numbers cost you deals (or your sender reputation), accuracy matters most. Cleanlist's waterfall approach delivers 98% accuracy. ZoomInfo and Apollo sit at 80-85%.

2. What's your budget?

Enterprise budgets open up ZoomInfo and Cognism. Mid-market teams should look at Cleanlist, Apollo, or UpLead. Bootstrapped teams might start with Apollo's free tier or Snov.io.

3. Do you need more than data?

If you need data + outreach in one tool, Apollo is the clear pick. If you need intent data, ZoomInfo. If you need accurate data to feed into your existing stack, Cleanlist.

Frequently Asked Questions

What is B2B data enrichment?

Data enrichment is the process of enhancing your existing contact or company records with additional information - emails, phone numbers, job titles, company size, technographics, and more. It fills gaps in your CRM and keeps records current.

How much does data enrichment cost?

Pricing ranges from $0.01/record (raw API access via PDL) to $2+/record (ZoomInfo at lower volumes). Most mid-market tools cost $0.10-0.50 per enrichment. Cleanlist's credit-based model works out to roughly $0.15-0.30 per full enrichment.

Can I use multiple enrichment providers?

Yes. Many teams layer providers - using one for initial prospecting and another for verification. Cleanlist's waterfall enrichment does this automatically across 15+ sources, eliminating the need to manage multiple subscriptions.

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 database, you get nothing. Waterfall enrichment queries multiple providers in sequence - if Source 1 misses, Source 2, 3, or 15 picks it up. Result: higher fill rates and better accuracy.

How often should I re-enrich my data?

B2B data decays at roughly 30% per year. Re-enrich active records quarterly and your full database at least twice a year. Email verification should happen before every major campaign.

Data enrichment is foundational. Every downstream activity - outreach, scoring, routing, reporting - depends on having accurate records. Choose a provider that matches your accuracy needs, budget, and workflow. And if accuracy is what matters most, start with Cleanlist.
