ZeroEval

ZeroEval offers a platform to capture AI agent traces, collect human feedback, and fine-tune model outputs through calibrated evaluations. The job it does: catching bugs before customers do, by hand or with automation.

It makes the most sense for engineering and QA teams. Related areas on their profile: Artificial Intelligence (AI) and Usability Testing. As a very small product team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

ZeroEval is based in San Francisco, California. Their site is zeroeval.com.
