Start Free — 30 CreditsThe Problem
Raw leads from webforms, events, and purchased lists arrive with just a name and email — sometimes not even that. SDRs waste 30-45 minutes per prospect researching company size, tech stack, and direct dials manually. At 50 leads per day, that is an entire team's week consumed by data entry instead of selling.
How Cleanlist Solves This
Cleanlist takes a sparse lead record (as little as an email address or company domain) and returns up to 40+ enriched fields: verified email, direct dial, mobile number, job title, seniority level, department, company name, industry, employee count, revenue range, tech stack, funding stage, and LinkedIn profile URL. Waterfall enrichment across 15+ providers ensures the highest match rate available.
Why Multi-Source Lead Enrichment Changes Win-Rate Math
Forrester's 2025 B2B Sales Benchmark found that opportunities where the seller had access to 10 or more data points about the prospect before first contact closed at a 28% higher rate than opportunities with fewer than 5 data points. The reason is straightforward: richer context enables more relevant opening messages, better objection handling, and more accurate qualification. But there is a catch — assembling 10+ data points from a single provider is unreliable because no single database has comprehensive coverage. In Cleanlist's internal testing, a single enrichment provider returned 10+ fields for only 41% of mid-market B2B leads. Waterfall enrichment across 5+ providers increased that to 87%. The implication for sales teams is clear: enrichment coverage directly correlates with win rates, and coverage depends on querying multiple sources, not just the best single source.

How It Works
Submit Leads for Enrichment
Upload a CSV, connect your CRM, or send leads via API. Each record needs at minimum one identifier: email address, full name + company, or LinkedIn URL.
Field Selection
Choose which data points to enrich: contact fields (email, phone, title), company fields (industry, size, revenue), technographics (tech stack, tools used), or all of the above. Only selected fields consume credits.
Waterfall Provider Cascade
Cleanlist queries the most likely data source first based on the lead's industry and geography. If the first provider returns incomplete data, subsequent providers fill the gaps — typically 3-5 sources are queried per record.
Data Normalization
Returned data is standardized: job titles are mapped to a seniority hierarchy (C-level, VP, Director, Manager, IC), company names are matched to canonical forms, and phone numbers are formatted to E.164 standard.
Confidence Scoring
Each enriched field receives a confidence score (High, Medium, Low) based on how many sources corroborated the data point. Fields with conflicting information across providers are flagged for review.
Deliver Enriched Leads
Enriched records sync back to your CRM with field-level mapping, download as CSV with original + new columns, or stream in real-time via webhook for instant routing to sales sequences.

Frequently Asked Questions
How accurate is Cleanlist's data?
+
Cleanlist achieves 98% email accuracy through real-time verification and cross-referencing across 15+ data providers. Every record is validated before delivery.
How many free credits do I get?
+
Every new account starts with 30 free credits. Each credit processes one record (enrichment, verification, or lookup). No credit card required to start.
What data providers does Cleanlist use?
+
Cleanlist uses waterfall enrichment across 15+ providers including major B2B data sources. The system automatically selects the best provider for each record to maximize match rates.
Can I connect my CRM?
+
Yes. Cleanlist integrates with HubSpot, Salesforce, and other CRMs. Enriched data syncs back automatically. You can also upload CSV files or use the REST API.
How long does it take to enrich my data?
+
Most jobs complete in under 2 minutes for up to 10,000 records. Larger files are processed in batches with progress updates.
What is the minimum information needed to enrich a lead?
+
A single work email address is enough for Cleanlist to return company data, job title, phone number, and firmographics. If you only have a name and company, Cleanlist can find and verify the email first, then enrich the full record. LinkedIn profile URLs also work as a starting identifier.
How does lead enrichment differ from data append?
+
Data append adds a specific missing field (like phone number) to an existing record. Lead enrichment is comprehensive — it fills all missing fields, verifies existing ones, normalizes formatting, and adds firmographic and technographic context. Enrichment gives you a complete, sales-ready profile rather than a single data point.
Can I enrich leads in real-time as they come in from webforms?
+
Yes. Cleanlist's API supports real-time enrichment with sub-3-second response times. Many customers connect it to their form handler or Zapier workflow so every new lead is enriched before it reaches the sales team.
