This directory lists 256 companies and products in the AI evals market. It covers builder evals, agent simulation, leaderboards, expert data, safety evaluators, AI security, runtime control, governance, cloud platforms, insurance and institutions.

It starts from a third-party market map, then checked. We added the companies the map lacked. On 5 November 2026 we fetched every company site with a script. We also checked funding or deal status for more than 100 rows against a dated source. Where we found no dated source for funding, the table says "Not verified".

We place each company by its main buyer and product, not by every feature. Segment calls are ours. Some cases are borderline, such as Promptfoo, QuantPi, Advai, Irregular and Epoch AI.

Key findings

  • Security and runtime control hold 113 of the 256 rows. AI security and red-teaming is the largest segment, with 74 rows. Builder evals and observability follow with 46.
  • The market is mostly American. US firms hold 171 rows, or 67%. Israel holds 24 rows, and 16 of them sell AI security. The EU holds only 26.
  • Consolidation hit builder evals and security hardest. Ten of 46 builder-eval rows and 10 of 74 security rows were bought or face a pending deal. None of the 34 governance rows and none of the 7 insurance rows did.
  • Security vendors are the main buyers. Security and network vendors account for 12 of the 23 deals. Data and observability platforms account for 6. Check Point, CrowdStrike and Palo Alto Networks each bought two.
  • Most of these firms are very young. Of the 247 rows with a known founding year, 130 (53%) were founded in 2023 or later. Insurers and certifiers are the youngest segment, with a median year of 2025.
  • Compliance is mostly a side feature. Only 60 rows check compliance as a core function, and 137 more check it in part. Security is a core check for 144 rows.
  • Vendor-paid third-party evaluators are rare. Only 8 of 256 rows have the evaluated vendor pay an outside party. Six are insurers or certifiers; the other two are Vals AI and Arena.

Step 1 of 8: 256 dots in one field.

We found 256 companies and product lines that build, run or sell AI evaluation, as of 5 November 2026.
AI security is the largest segment, with 74 rows. Add runtime control and guardrails, and security-led products hold 113 of the 256.
Governance and compliance tools form the fourth group, with 34 rows. All of them are still independent or long-standing product lines. None was bought.
US firms hold 171 rows, or 67%. The US also hosts all 17 cloud-platform rows and all 14 expert-data rows.
Israel punches above its size, with 24 rows. Sixteen of them sell AI security.
The EU holds only 26 rows. They sell runtime control (8), builder evals (7) or governance (7), among others.
Twenty-three rows were bought or face a pending deal. Ten are builder-eval tools and ten are security firms. Security and network vendors made 12 of the deals.
Another 29 rows are product lines of larger firms. Fifteen are cloud and data platforms that bundle evals into a bigger bill. Datadog charges no separate fee for them.

All 256 directory rows regrouped by segment, HQ region and status, as of 5 November 2026. Segment placement is our call.

For product lines, the year is the parent firm's founding year, so the platform segment looks old. Five firms founded before 2000 (IBM, Microsoft, Cisco, Check Point, NVIDIA) sit in the left bin.

How to read the table

Verification marker

  • ✓ Checked (127 rows). A dated source confirms the funding or deal figure, or the row rests on a cited source.
  • – Funding not verified (111 rows). We found no dated source for funding, so the table shows "Not verified".
  • † General knowledge (18 rows). HQ or founding year comes from general knowledge, which we did not check in this pass.

HQ and founding year for rows from the third-party market map come from that map. We did not re-check them.
