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

Braintrust is committed to addressing challenges in the development of large language models (LLMs), such as the unpredictability of non-deterministic models and natural language input. The platform has collaborated with top teams like Notion, Stripe, and Airtable to help users improve AI product quality through continuous experimentation. Braintrust user teams run more than 10 experiments on average each day. Additionally, Braintrust has launched a new feature called 'Functions' that allows users to create tools, prompts, and scorers directly in the codebase and upload them to the platform with simple commands, optimizing the experimentation and deployment process while reducing infrastructure management time.

It should be noted that although it shares the same name as the Web3 talent network Braintrust, these are two different companies.
