Building One with Tomer Cohen · 2026-02-17 · 30 min
What if the biggest problem in healthcare isn’t diagnosis - it’s capacity? On this episode of Building One, Tomer Cohen sits down with Dr. Thomas Kelly, co-founder and CEO of Heidi , to unpack what it actually takes to build AI for one of the most complex, regulated, and human industries in the world. Before starting Heidi, Tom was a vascular surgeon. He saw firsthand how some of the most highly trained people on the planet were spending their days on low-value administrative work. Heidi began by listening to real patient visits and drafting clinical notes. Today, it’s expanding into the vast - and invisible - work around care: follow-ups, calls, scheduling, and coordination. In this conversation, we explore: What “doubling capacity” in healthcare really means Why personalization must be nearly perfect - measured almost like a clinical SLA What it takes to build AI that doctors actually trust How GPT-4 didn’t kill Heidi’s moat - it forced a radical pivot And how Heidi rewrote the healthcare go-to-market playbook by winning clinicians one by one Everyone talks about AI’s potential.
