We use CompanyEnrich for our product. I really like their clear documentation, and the best part is that you can view and copy the API call you configured in the UI. It’s super convenient.

The MCP server is what sold me. I connected CompanyEnrich to Claude and to ChatGPT Codex, and now my agents can pull live company and people data in the middle of a task instead of guessing or searching the web.<br><br>In practice, I can ask Claude to find B2B SaaS companies in a region within a certain headcount range, pull the founders, and draft a first message for each, all in one conversation. I also use it to check a company before a call, to find lookalikes of accounts that already worked for me, and to work out who is actually behind a list of LinkedIn post engagers. The agent does the research and the data comes from a source I trust, so I spend less time copying between tabs.<br><br>I've tried other data providers. Some return more fields and some advertise unlimited lookups. In my experience the data was often outdated or wrong, and a big list of wrong contacts costs more time than it saves. CompanyEnrich has been more reliable for me.<br><br>Coverage is the other reason. Their published benchmarks, which you can rerun yourself, put them first on company coverage in both the people search test (88% of 502 companies) and the company enrichment test (67.6% of 349 domains).

I find CompanyEnrich to be a good source for well-targeted companies and a solid starting point for list building. The data quality and coverage are good, which is important for our needs. I particularly like the number of useful endpoints they offer, as well as their workforce data, which speaks to their excellent per-company data coverage. Additionally, the initial setup was very easy, which made the process smooth.
