🎧 Startup Growth Podcast, Ep. 15: John Paul Mussalli — How One EMT's Scrappy Prototype Evolved Into an AI Tool That Won Over 20% of NYC's EMTs
From 20-minute reports to 2-minute workflows: the fastest-growing EMT AI tool in NYC.
John Paul Mussalli is the co-founder and COO of CareSwift, a Y Combinator-backed startup building AI-powered software to streamline documentation for EMT workers.
JP and his cofounders brings a unique blend of technical expertise and entrepreneurial drive to the healthcare technology space, having previously worked across diverse fields from real estate automation to web development.
Since co-founding CareSwift, he's helped scale the platform to serve over 2,000 EMTs in New York City alone, generating more than 90,000 automated reports. Beyond product development, JP leads go-to-market strategy and is currently pursuing EMT certification himself to deepen his understanding of the industry's challenges.
