About this directory

A verified directory of companies that test AI products, organised by what they test and where they work, ranked by a published coverage score. No paid placement.

Publisher

AI Testing Vendors is published at aitestingvendors.com. Entries are verified by AI Testing Vendors.

Independence

This directory accepts no payment for listing, placement, badges or removal. Vendors cannot buy a position: every list is ordered by one published coverage score, computed the same way for every entry from verified data. Entries are built from each vendor's own published pages and from independent sources named next to every figure.

Funding

The site is funded by its publisher. It carries no advertising and no affiliate links. If this changes, the change is dated in the changelog and this statement is updated.

Ratings and reviews

No star ratings, review counts or client testimonials appear on this site. Review platforms are used only as a second source for headquarters, founding year and size band.

Listing policy

Any company that tests AI products for clients and has a public page describing that service can be listed. Listing is free and cannot be bought. A request is a plain email to contact@aitestingvendors.com with the company name and the URL of the AI testing page. The entry is built by the same process as every other entry; the vendor does not write its own entry and does not approve it. Software vendors without a testing services practice are out of scope.

Contact

Email contact@aitestingvendors.com. How entries are built is described on the methodology page; the full data set is on the data page.
