The short answer
31 products in this directory are tagged with this job. 26 of the 34 tagged entries have an official MCP server and 2 have a community one, so an agent can call 28 of them directly. 21 are reachable by one person without a contract. Counted 2026-08-25.
Domain to company is the most common single call in a GTM agent's loop, because a domain is the one identifier that arrives from everywhere: a form fill, an email address, a news item, a website visit. It is also the most widely tagged job in this directory's enrichment family.

What this list is not
It is not a ranking and it is not a recommendation. A job tag means the vendor says the tool does
this. Nobody here has run any of them: 0 tools in this directory are bench tested.
Two tools on the same list can be wildly different in coverage, price and quality, and this
directory does not claim to know which.
Sources
Every number on this page is generated from directory.json at build time and carries
the date it was baked: 2026-08-25. Nothing is typed by hand, nothing is rounded, and nothing is
estimated. The underlying data is published in full. Where the honest
answer is a zero, the zero is printed.
