Cleanlist, shown on its site as Cleanlist AI, is a B2B prospecting and data enrichment platform organized around an AI agent named Clu. Users describe a go-to-market job in one sentence, and Clu builds an agent that finds buyers, verifies their emails and starts outreach.
The platform replaces a stack of separate tools for search, enrichment, verification, sequencing and CRM upkeep. It searches more than 1 billion profiles and draws contact data from over 25 providers.
Cleanlist reports 10,000+ users, ranging from individual founders to full sales teams, and shows a 5.0 rating on G2, 4.7 on the Chrome Web Store and 4.8 on AppSumo.
Building an agent follows five steps. The user states who to find, how many per week and where they should go. Clu then asks about missing details such as titles, what counts as new, the run day and the spend limit per person.
Clu draws the play on a canvas, where each step shows its filters and price and can be edited in plain English. A test run on 25 people lists the contacts and verified emails it would add, spends no credits and writes nothing to a CRM.
After one confirmation, the agent runs on its schedule, for example every Monday at 8:00 AM, enriches and verifies new people, starts the sequence and posts the run summary to a Slack channel.
The core of the product is waterfall enrichment. Cleanlist asks each of 25+ providers in order for a work email, verifies the first result and keeps it, then repeats for phone numbers. Searching is free, and email validation for your own lists costs 0.5 credits per address.
Agents are the second pillar. A library of 12 covers prospecting, CRM hygiene, research and reporting, including duplicate cleanup, inbound routing, account briefs and a weekly pipeline summary. Agents run on schedules or CRM triggers.
Other tools include sequences sent from a rep's own mailbox, AI research on each lead with sources, ICP scoring from 0 to 100, a Chrome extension, a REST API, SDKs and an MCP connector for Claude and ChatGPT.
