What Braintrust does
Braintrust traces prompts, responses and tool calls of AI agents in production and lets teams run evals against versioned datasets with LLM, code or human scorers. Its discovery features surface recurring patterns in traces, and the Loop agent proposes better prompts, scorers and datasets. It is used by engineering and product teams building AI products.

How does usedby know who uses Braintrust?
Each company is linked to a public page that names it: Braintrust's customer page, a published case study, a press release or a job post. We save each page with a dated capture and check it again on each run. A company leaves the list only after three checks in a row that no longer find it, and at least 14 days after it was last seen. A company with a published case study or quote is never removed automatically.
What do confirmed, observed and signal mean?
Confirmed (15): a case study, a named quote or a press release. Observed (24): Braintrust shows the company on its own pages, for example a logo wall. Signal (0): a job post shows the company’s employees use Braintrust, the weakest proof. Every level counts as a customer, and each line shows its level.
