Chronicle Labs provides staging environments for enterprise AI agents. The platform captures operational events and lets teams backtest new agent behaviors against real production scenarios, so they can safely deploy changes without risk to users. The company was founded by Ayman Saleh, who previously worked at NASA JPL on the Mars 2020 Perseverance rover and the James Webb Space Telescope and led engineering at FlightWave, and Rowan Zyadeh (COO). Chronicle Labs is based in the San Francisco Bay Area and is part of Y Combinator's Spring 2026 batch.
