Investors are named from the companies' own announcements, the investors' own pages, Y Combinator's company pages, public filings and news reports of a round, each with its source and the date it was researched. An investor isn't a sign of quality, and nobody can pay to be listed or to change a grade. To correct something or have a page removed, write to privacy@anchorterminal.com.

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
