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.
Alex Shan is the 22-year-old co-founder and CEO of Judgment Labs, a San Francisco startup building the continuous-improvement stack for AI agents. A former Stanford NLP researcher under Chris Manning who pioneered autonomous networking agents at Juniper Networks, Shan started Judgment with two childhood best friends to give teams tools that understand what their agents are actually doing - not just their inputs and outputs. In May 2026 the company closed $32 million in combined seed and Series A funding led by Lightspeed Venture Partners.
