Enrich Your SaaS Leads with Verified Data
Upload the list and Cleanlist AI verifies the contacts you have, then fills missing work emails and phone numbers from 25+ providers. Coverage varies by industry, and you pay only for the rows that come back.
A Cleanlist AI list called PLG product leaders enriched through the waterfall: 4 verified work emails and 3 phone numbers found for 4 leads, 34 credits in total. Rows with no phone number found cost nothing for that field.

How does Cleanlist AI enrich your SaaS leads with verified data?
Cleanlist AI enriches SaaS leads with the specific data points that matter for software sales: firmographic context (industry, employee count, location), and verified contact information for the economic buyer rather than just the free trial user. The waterfall tries 25+ providers in sequence, so a young startup that one vendor has never indexed can still come back with a match.
Why this is hard to do by hand
SaaS teams pull in a lot of leads through free trials, product-led signups and content, and most arrive with an email address and a company name. Before an SDR can qualify one, someone has to look up funding, headcount and who signs the contract. In product-led sales, the faster you reach a good signup the more likely it converts, so every hour of research costs deals.
SaaS companies that enrich leads within 5 minutes of signup see 3.2x higher conversion
3.2xhigher conversion for leads enriched within 5 minutes
A 2025 OpenView Partners study found that SaaS companies that reached high-ICP trial signups within 5 minutes converted them at 3.2x the rate of companies that waited 24 hours or more. The usual blocker is data. Teams can't tell which signups are high-ICP without enrichment, and researching by hand takes too long. With the Cleanlist AI API, each signup gets company size, funding stage and a fit score as it arrives. Enterprise signups (200+ employees, Series B or later) go to an AE's queue with full context, and smaller ones go to self-serve onboarding. SaaS customers on real-time enrichment report 45% shorter time to first meeting and 28% higher free-to-paid conversion than before they started.

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
Bring in your lead list
Pull leads from your CRM or upload a CSV export from your product analytics tool. Cleanlist AI picks up the usual fields: work email, company domain and signup source.
- 02
Pick the fields that matter for SaaS
Choose firmographics (funding stage, revenue, employee count) and the buyers you want contacts for (VP of Engineering, CTO, Head of Product).
- 03
Search providers that know startups
Cleanlist AI works through providers in sequence, including ones that specialize in technology companies and startups, so early-stage and bootstrapped companies have a better shot at a match.
- 04
Score signups by ICP fit
Use the firmographics to score each lead against your ICP, for example Series A to C companies with the headcount your product fits.
- 05
Route leads to sales
Sync scored leads to HubSpot or Salesforce, or push them to Salesloft or Lemlist. Each one arrives with a verified email, a phone number, company context and a fit score.
- 06
Enrich signups as they arrive
Call the Cleanlist AI API (Pro plan and up) when a trial starts, and send the signups that fit your ICP straight to a rep.

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.

| Funding stage and headcount | LinkedIn company pages, one at a time | Appended from the same waterfall |
| Startup coverage (pre-Series A) | Crunchbase manual lookup | 25+ providers tried in sequence |
| Qualifying 100 trial signups | Research each one by hand | One enrichment run, then sort by fit |
| Competitor user detection | Ask during sales call | An AI research column checks the account's public footprint |

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.
Does Cleanlist AI have good coverage for my industry?
Coverage varies by industry, so Cleanlist AI asks 25+ providers in sequence until one returns a deliverable result. On our 500-lead benchmark, Cleanlist AI returned 98% verified work emails and 85% phone numbers.
Can Cleanlist AI detect if a lead is using a competitor's product?
Only through research. Cleanlist AI has no filter or dataset for the tools a company uses. An AI research column can read a company's public footprint and write back any evidence it finds for a given tool, at 5 credits per lead. Have a rep confirm it before you act on it.
How does Cleanlist AI handle product-led growth (PLG) lead volumes?
Most PLG signups arrive with just an email. The Cleanlist AI API (Pro and up) can enrich each one at signup with company data, employee count and funding stage, so you can score it and route it to sales or self-serve right away.
Does Cleanlist AI have good coverage for early-stage SaaS startups?
Yes. The waterfall includes providers that focus on startup data (funding, founding date, team size) as well as mainstream B2B ones. Very small companies are the hardest segment for every provider, which is why the waterfall tries several in a row.
