Company Description
Braintrust is a software development company that provides an enterprise-grade platform for building artificial intelligence products. The platform is designed to unify iteration, evaluation, monitoring, and review into a single system, enabling teams to build and ship reliable AI applications. It offers tools such as prompt playgrounds, data management, and observability features. The company was founded in San Francisco in 2023 by Ankur Goyal, who previously founded Impira, a company later acquired by Figma. Braintrust was established to bring more structure and reliability to the AI development process and works with clients including Notion, Stripe, Vercel, and Ramp.
Looking forward, Braintrust is focused on advancing AI software engineering with a product direction centered on trust, observability, and enterprise governance. The company has shown significant momentum, raising $36 million in a Series A funding round in June 2024, which brought its total funding to approximately $45 million. It was also recognized as an Intelligent Applications 40 (IA40) 2025 winner. The platform's real-world impact is highlighted by client case studies; for instance, Graphite utilized Braintrust to transition from ad-hoc manual testing to systemic evaluation for its AI code reviewer. Similarly, Ramp has endorsed the company for providing a data platform to ingest and query AI inputs and outputs at scale.
