What is Cleanlist?
Cleanlist is a B2B data enrichment platform that uses waterfall enrichment to query 15+ data providers and return verified contact data with 98% accuracy. It helps sales, marketing, and RevOps teams clean, verify, and enrich their lead databases.
How Cleanlist Works
Cleanlist uses waterfall enrichment - a cascading approach that queries multiple data providers in sequence. For each contact, Cleanlist checks Provider A first. If the data is incomplete, it moves to Provider B, then C, and so on through 15+ sources. The best data from each source is merged into a single verified record.
This is fundamentally different from single-source tools like ZoomInfo or Apollo, which rely on one proprietary database and accept whatever gaps that database has. Waterfall enrichment achieves 85-95% field coverage versus 50-70% from single-source providers.
