Who sells AI training data, RL environments and evals
The 174 companies listed on Oct 27, 2026, in one image. We placed each in one section, by our read of what it mainly sells, checked against its listing's tags. 109 of the 174 sell RL environments.
This edition is fixed as of Oct 27, 2026 and isn't updated as listings change: the directory lists 187 companies today. For current facts and sources, use the directory or the data downloads.
Sections and counts
Most companies sell more than one thing, so each section has two counts. Lead with it: companies placed in that section. Sell it: every company tagged for that section on Oct 27, 2026, so a company can count in several. In the four RL environment sections, that means tagged RL environments plus one of the section's domains (Enterprise & professional work, for example, covers Enterprise workflows, Finance, Legal and Medical). 5 of the 174 were acquired and are marked acq. on the map.
