LLM Eval and Observability Platform
We build a platform called Confident AI that benchmarks, safeguards, and improves large language model applications. Our product offers best-in-class evaluation metrics and guardrails using our own open-source evaluation algorithms from DeepEval. It gives engineering, product, and design teams practical tools to monitor and improve AI system quality over time.
We live and operate in San Francisco, CA, and the company would remain based here after YC.
San Francisco is where we have our network, early users, and talent. Staying local keeps us close to customers and the AI ecosystem as we continue product development.
