## About

Based in California, US, and founded in 2023 by CEO Ankur Goyal, Braintrust Data, Inc., trading under the name Braintrust, operates as a software company that focuses on creating an end-to-end platform for advanced AI application development. In February 2026, Braintrust Data, Inc. raised USD 80 million in series B funding led by ICONIQ Capital, with participation from Andreessen Horowitz, Base Case Capital, and Greylock Partners.


Braintrust offers an end-to-end platform designed for the development of advanced AI applications, particularly focusing on large language model (LLM) products. Its core offerings facilitate the iterative workflows necessary for building robust applications in the face of non-deterministic models and unpredictable natural language inputs. Users can leverage Braintrust’s evaluation framework, which comprises prompts, scoring mechanisms, and example datasets, to optimize LLM performance over time. The platform is tailored for both technical and non-technical team members, allowing integration and versioning of datasets. Braintrust primarily serves clients in technology, finance, and healthcare sectors across North America and Europe, catering to teams engaged in AI application development and deployment.

Braintrust generates revenue through subscriptions to its platform packages, which include Builder, Enterprise, open source, and .edu. These subscriptions enable organizations to access the platform's suite of tools and features, including prompt tuning, performance tracking, and real-time execution analysis. Transactions typically occur on a B2B basis, wherein enterprises integrate Braintrust into their AI development lifecycles.

The company plans to use its proceeds from February 2026 funding to build infrastructure that helps teams measure, test, and improve artificial intelligence products and support broader customer adoption.
