Company Overview

About Braintrust

Braintrust is an AI observability and evaluation platform founded in 2023 by Ankur Goyal in San Francisco. The platform enables engineering teams to build, test, monitor, and improve AI products by providing tools for prompt engineering, dataset versioning, automated scoring, trace inspection, and quality measurement. Goyal previously founded Impira (acquired by Figma) and led Figma's AI team.

Business Model & Competitive Advantage

Unlike traditional application monitoring tools, Braintrust is purpose-built for AI workflows, offering an evaluation-first development approach where every code change is tested against quality benchmarks before deployment. The platform includes a collaborative prompt playground, side-by-side model comparison, and version-controlled eval infrastructure. Its customer base includes Notion, Replit, Cloudflare, Ramp, Dropbox, Vercel, Navan, and BILL.

Competitive Landscape 2025–2026

In February 2026, Braintrust raised $80 million in Series B funding led by ICONIQ Capital, with participation from Andreessen Horowitz, Greylock, and Basecase Capital, valuing the company at $800 million. Total funding reached $121M. The rapid valuation growth from $150M to $800M reflects surging enterprise demand for AI observability tooling.
