Braintrust

At Braintrust, we believe the best AI products are built through collaborative iteration. Our engineers ship features daily, product managers prototype directly in the UI, and everyone reviews results together in real time. We've designed our platform around the principle that evals should be part of mainstream engineering workflows - not an afterthought. Our small team of builders values velocity without sacrificing quality, which is why we've created a platform where teams can iterate, evaluate, and ship AI applications with confidence.

We don't just build tools for AI development; we're reimagining how teams work together to turn production data into better AI with every release. Our culture emphasizes shipping, community, and developer love. We tackle hard problems - from building real-time data pipelines to creating intuitive interfaces for evaluating LLM performance - because we know that reliable AI requires more than just good models. It requires a shared understanding of what works and what doesn't. That's the foundation of everything we build at Braintrust.
