CareSwift builds an AI scribe for ambulance reports, providing a real-time AI assistant embedded directly into ambulance reporting systems. The assistant guides medics through documentation and flags errors, helping crews complete accurate, compliant reports in under three minutes, cutting documentation time by roughly 80% and reducing insurance claim denials. The company was co-founded by Brian Weigand, an EMT who spent four years in the NYC 911 system and previously built ambulance reporting software, and Jonathan Zero. CareSwift was founded in 2025 and went through Y Combinator's Summer 2025 batch.
