Enrich Your B2B Database with Verified Data
Enrich Your B2B Database: upload a CSV or connect your CRM, and Cleanlist AI checks each row against 25+ providers in sequence. Every new workspace opens on Pro for 14 days with 250 credits, 3 seats.
A Cleanlist AI list called Series B sales leaders enriched through the waterfall: 6 verified work emails and 4 phone numbers found for 6 leads, 46 credits in total. Rows with no phone number found cost nothing for that field.

How does Cleanlist AI enrich your B2B database with verified data?
Cleanlist AI enriches your entire B2B database at the contact and company level simultaneously. Contacts get verified emails, phone numbers, current job titles and social profiles. Companies get employee count, industry and HQ location. For each segment, the waterfall tries the providers strongest there first.
Why this is hard to do by hand
Most B2B databases, bought or built, are thin: names and emails and not much else. Without company context you can segment by geography and industry at best, so your SDRs work a 5-person startup the same way they work a 500-person scale-up.
Firmographic enrichment improves lead scoring accuracy by 47%
47%improvement in lead scoring accuracy with firmographic data
TOPO Research (now Gartner) found that lead scoring models built only on behavior (site visits, email opens, content downloads) predicted sales-readiness correctly 38% of the time. Adding firmographic data (employee count, revenue, industry, funding stage) took accuracy to 56%, a 47% improvement. Behavioral signals show interest and say nothing about fit. A 3-person startup downloading your enterprise pricing guide is very interested and a poor fit; a 500-person company in your target vertical that visits the homepage once is mildly interested and a great fit, and the model needs to see both. Cleanlist AI's database enrichment adds the firmographic layer most scoring models are missing. Customers who rebuilt their scoring after enriching reported 31% fewer unqualified leads passed to sales and 19% shorter sales cycles on qualified opportunities.

What a lookup costs
Each lookup walks 25+ providers in cost order, and you're charged once for what comes back: 1 credit for a verified work email, 10 for a phone number, 11 for both. Validation is 0.5 and AI qualification is 5. A lookup that finds nothing is free, and the whole team pays from one wallet.

How it works.
- 01
Upload or connect the database
Import a CSV (up to 1M records per file), connect your CRM, or push records through the REST API. Cleanlist AI maps your columns to enrichment fields whatever the schema.
- 02
Health check first
Before anything is enriched, Cleanlist AI reports on the database: record count, fill rate by field, data age, duplicates and expected enrichment coverage. The assessment costs no credits.
- 03
Choose what to enrich
Pick the contact and company fields you want by category (contact details, firmographics, social profiles), then set a credit cap so the run can't overspend.
- 04
Run the waterfall in batches
Cleanlist AI works through the records in batches and sends each one first to the providers most likely to match it, by industry, region and company size. Fill rates and match rates update as it runs.
- 05
Reconcile with what you had
New data is checked against your existing records. New fields are added, outdated ones are flagged for update, and conflicts go to review. Each enriched value carries a confidence score.
- 06
Export or sync
Download the database with its original and new columns, push the updates to your CRM, or pull records into your warehouse through the API. Schedule repeat runs to keep it current.
What you get.
98% verified work emails
That's on our 500-lead benchmark. Cleanlist AI checks each email and flags catch-all and disposable addresses before you send.
25+ data providers
Cleanlist AI asks them one at a time and stops at the first deliverable result. When one provider has nothing, the next one gets its turn.
No code required
Upload a CSV or connect your CRM. If your engineers want it, the API is there from the Pro plan.
14-day Pro trial
250 credits and 3 seats on Pro for 14 days. You don't need a card or a sales call to start.
Manual process vs Cleanlist AI.
| Feature | Manual | Cleanlist AI |
|---|---|---|
| Enrichment scope | Contact-level only (name, title, email) | Contact and company fields, with AI columns for anything account-specific |
| Match rate | Whatever one provider happens to cover | 98% verified work emails and 85% phone numbers on our 500-lead benchmark |
| Account research outside the standard fields | A separate tool, or a rep on Google | An AI research column per account, 5 credits per lead |
| Processing 100K records | Weeks of research across several tools | Batch jobs, with a credit cap you set |
| Keeping data fresh | A snapshot that starts aging on day one | Scheduled re-enrichment |
How accurate is Cleanlist AI's data?
Cleanlist AI returned 98% verified work emails and 85% phone numbers on our 500-lead benchmark, pulling from 25+ data providers. Each lookup stops at the first deliverable result, meaning a verified or likely-valid email.
What do I get when I sign up?
A 14-day Pro trial: 250 credits, 3 seats, and every Pro feature. After it, the Free plan gives you 50 credits a month. A verified work email costs 1 credit, a phone number 10, and a miss nothing.
What data providers does Cleanlist AI use?
Cleanlist AI runs a waterfall across 25+ B2B data providers. For each record it asks one, moves to the next when that one has no match, and stops at the first deliverable result.
Can I connect my CRM?
Yes. HubSpot and Salesforce sync both ways on the Pro and Enterprise plans, and Salesloft and Lemlist take a one-way push. You can also upload a CSV, or use the REST API from Pro.
How long does it take to enrich my data?
It depends on the size of the file and how far down the waterfall each row has to go. Cleanlist AI runs the whole CSV as one job, so you upload once and download or sync the results when it's done.
How large of a database can Cleanlist AI enrich in a single run?
Up to 1 million records per batch job. A bigger database runs as a series of batches, one after another, without anyone stepping in. Credits are usually the practical limit: 1 per verified work email, 10 per phone number, nothing for a miss.
What technographic data does Cleanlist AI include?
None. Cleanlist AI has no technographic dataset and no technology filter in search, so you can't target accounts by the tools they run. On a list you already have, you can add an AI column that researches each account on the open web and answers a prompt, such as which CRM the company names publicly. That is a research result per row, at 5 credits a row, and you can't query it like a feed.
Can I enrich only the records that have changed since my last enrichment run?
Yes. Cleanlist AI keeps enrichment history and can run only the records that are new, recently modified or past the freshness threshold you set. You only spend credits on those rows.
