Full-Time About Judgment Labs Judgment Labs builds infrastructure for Agent Behavior Monitoring (ABM), helping organizations evaluate and monitor AI agent performance in production environments. Their platform identifies behavioral anomalies such as instruction drift, retrieval degradation, and reliability failures across complex workflows. The company has raised more than $30M from investors including Lightspeed, SV Angel, Valor Equity Partners, Chris Manning, Michael Ovitz, Michael Abbott, Cory Levy, and Kevin Hartz.
