About Composo

At Composo.ai, we hear everyone wants to ship AI features & agents fast, and with high confidence. However, what we hear from teams, is that: "We have no idea if prompt & model changes made things better or worse" “I’m terrified of what customers will find that we missed” “We’re spending weeks on evals instead of shipping features” “How do the best AI teams ship daily with complete confidence? What are we missing?" Well, the best teams run 1000s of automated, deterministic evals daily. They get instant drift & error detection in production, and can test each prompt or model change in minutes. They do this with Composo - which is the only API for high accuracy, low variance evals at scale. Plug it in with a few lines of code, define your criteria in a single sentence of english, and get immediate insight on errors even for large multi-agent systems.
