# Bespoke Labs Raises $40M Series A for AI Agent Training Infrastructure

> Bespoke Labs raised $40 million (Series A + seed combined) to build environments where AI agents safely learn, test, and improve before production deployment. Founded by ex-Anthropic and Meta researchers, the company addresses a critical gap: agents are only as reliable as the environments they trained in. Led by Wing VC with participation from Mayfield, dbt Labs CEO Tristan Handy, and angels from Anthropic/OpenAI/Meta, the round signals investor confidence that the bottleneck is not model size, it is agent reliability infrastructure. Bespoke Labs will use the capital to expand research, scale environment-building tools, and cement itself as the standard for agent pre-deployment testing.
