Judgment Labs

Judgment Labs is a San Francisco applied-research startup building the continuous-improvement layer for AI agents. Its platform and open-source SDK, Judgeval, trace, evaluate, and monitor 'deep agents' - systems that reason, plan, use tools, and remember - turning messy production data into measurable, repeatable improvements. Founded in 2026 by three childhood friends out of Stanford, it raised $32M in combined seed and Series A funding led by Lightspeed Venture Partners.
