Their lookalike algorithm is incredibly precise. It makes discovering new, similar companies a total breeze.

The API is really good and easy to implement.

I work in B2B SaaS and run a lot of outbound and content research. CompanyEnrich quickly became my default for company-level data. The lookalike search is the standout for me. I drop in a domain and get back genuinely similar companies, not random matches that share one industry tag. For niche ICPs that Apollo and ZoomInfo miss, this is a real edge. Semantic search is the other feature I use weekly. I can type something like "B2B sales engagement platforms in the US under 200 employees" and get clean results without wrestling with ten filters. The Clay integration is smooth, and the API is well-documented enough that I had a working enrichment flow running inside an hour. Data quality on smaller and harder-to-find companies is noticeably better than the older providers I used before.
