PANews reported on December 19 that AI software engineering platform Braintrust announced the completion of a $36 million Series A financing round, led by Martin Casado of Andreessen Horowitz, with participation from existing investors Elad Gil, Greylock, Basecase, Datadog, Databricks Ventures, Guillermo Rauch (Vercel), Simon Last (Notion), Bryan Helmig (Zapier), etc. This round of financing brings Braintrust's total financing to $45 million.

Braintrust is committed to solving challenges in the development of large language models (LLMs), such as non-deterministic models and the unpredictability of natural language input. The platform has worked with top teams such as Notion, Stripe, and Airtable to support users in improving the quality of AI products through continuous experimentation. The Braintrust user team runs more than 10 experiments per day on average. At the same time, Braintrust launched a new feature "Functions", which supports users to create tools, prompts, and scorers directly in the code base and upload them to the platform with simple commands, optimizing the experiment and deployment process and reducing infrastructure management time.

It is important to note that although it has the same name as the Web3 talent network Braintrust , these are two different companies.
