Thomas Kelly

CEO and Co-Founder

Heidi

New York City, NY

Dr. Kelly co-founded Heidi by drawing directly on his experience as a former vascular surgical resident, where he lived firsthand the administrative burden that left clinicians burned out and patients underserved. Under his leadership, Heidi has become one of the fastest-growing healthcare AI companies globally, achieving 15,323% three-year growth and earning the No. 1 spot on the Deloitte “Fast 50,” while scaling to a $465 million valuation and raising nearly $100 million in funding. The platform now supports over 2.4 million patient consults every week across 110 languages, more than 200 medical specialties, and tens of thousands of clinicians in 116 countries, ultimately saving providers more than 31 million hours in the last 18 months alone through scribing and workflow tools. Heidi’s differentiated commitment to designing solely with the clinician experience in mind has driven higher-than-industry-average adoption rates and made the platform indispensable to leading U.S. health systems and more than 1.5 million NHS appointments monthly in the U.K. Dr. Kelly’s mission to double the world’s healthcare capacity by empowering every clinician with an AI care partner reflects a long-term commitment to equity, access and sustainability in healthcare. He has earned the College of Healthcare Information Management Executives “Foundation Partner of the Year Award.”
