Braintrust

We are building a platform that helps developers build world-class AI products. AI development is a relatively new paradigm combining code and datasets, incrementally refining both using frequent evaluations. Our product lets you evaluate LLM applications and iteratively improve them, with a rich set of tools to visualize changes and interrogate failures. Developers integrate Braintrust into their continuous integration and development loops, often running 50+ experiments per day. Our team includes AI, design, and database veterans who have exited multiple companies and worked at Figma, Nuro, Impira, MemSQL, Google, and Twitter. We're backed by Elad Gil, Base Case Capital, and leading CEOs/founders.
