Profile
Braintrust provides a platform for monitoring, tracing, and evaluating AI models in production, helping teams catch regressions and improve quality with each release.
Braintrust Data, founded in 2023 by Ankur Goyal, is an AI observability and evaluation platform headquartered in San Francisco, California. The company provides engineering and product teams with tools to monitor, trace, and evaluate AI models in production, capturing multi-step agent interactions and intermediate reasoning data. Its platform combines observability (real-time trace ingestion, latency and cost tracking), evals (prompt engineering, versioned datasets, automated and human scoring), and automation (pattern discovery via Topics, continuous online scoring, quality gates).
As of mid-2026, ZoomInfo estimates Braintrust's annual revenue at $25.8 million and headcount between 51 and 200 employees. The company is venture-backed, though specific funding rounds and amounts have not been publicly disclosed in the dossier. In May 2026, Braintrust confirmed a security breach where hackers accessed one of its Amazon cloud environments, prompting the company to ask every customer to rotate sensitive API keys.
The incident was reported by TechCrunch and represents a significant operational and reputational challenge. Braintrust's customers include notable AI-forward companies such as Notion, Stripe, Zapier, Vercel, Ramp, Replit, Cloudflare, and Dropbox. The company is actively hiring for senior roles, including a Head of Finance, indicating a focus on scaling financial operations and strategic planning. Braintrust's product portfolio is framework-agnostic and integrates with existing AI stacks, positioning it as a vendor-agnostic observability layer for production AI systems.
