🎧 New Ep: John Paul Mussalli — How 3 Friends Built an AI Tool That 20%+ of NYC EMTs Now Use

Hey There,

The newest episode of The Startup Growth Podcast is live!

Listen to the episode here.

I sat down with John Paul Mussalli, 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.

In this episode, we explore the journey from scrappy prototype to venture-backed startup and the critical lessons learned along the way.

Key topics covered:

• How a ChatGPT prototype evolved into a venture-backed healthcare AI platform

• The hidden costs of poor EMT documentation: $1,800 per error and 11% industry revenue loss

• Why 25% of New York's EMTs organically adopted CareSwift without marketing

• Critical incorporation mistakes that can delay funding and how to avoid them

• The strategic decision to expand from narrative reports to full documentation workflow

• Why domain expertise matters when building AI for specialized industries

• Navigating regulatory compliance and the founder stack for healthcare startups

• The reality of Y Combinator: 996 work culture and rapid iteration cycles

• From 15-20 minute reports to 2-minute automated workflows saving hours per shift

• Why sometimes a bug in Apple Mail can redirect your entire startup journey

I hope you find this educational content valuable and can apply it in your business.
