Confident AI

Confident AI is a San Francisco startup (YC W25) that builds the evaluation and testing layer for LLM applications. Its open-source frameworks DeepEval and DeepTeam - often described as 'Pytest for LLMs' - let engineers unit-test, benchmark, red team, and monitor chatbots, agents, and RAG pipelines with research-backed metrics. The cloud platform adds dataset management, observability, adversarial testing, and governance so teams can prove AI quality before and after shipping.
