Ryan Gallagher is a Stanford- and Harvard-trained physician turned founder who runs Clarion, the AI communication layer for healthcare. After helping build two breakout digital-health companies, Two Chairs and Ophelia, to $100M+ valuations, he started Clarion in 2024 to fix the unglamorous problem that swallows clinics whole: the phone. Clarion's AI agents answer the calls, texts and web chats that overwhelm front desks, handling scheduling, billing, refills and referrals end to end across 84+ EHR systems. Backed by Accel, Y Combinator and Sequoia scouts, the New York company already serves tens of thousands of patients a month.
