Clarion

Clarion builds an AI communication layer for healthcare that answers the phones, texts, and web chats clinics can't keep up with. Its voice, SMS, and web agents handle scheduling, prescription refills, billing questions, referral intake, and after-hours follow-up, integrating with 80-plus EHR systems including Epic and Cerner. Founded in 2024 by a Stanford/Harvard-trained physician and an ex-Amazon Alexa voice-AI engineer, the New York company is a Y Combinator W24 startup backed by Accel and Airtable Ventures, and says it serves tens of thousands of patients a month across virtual-care companies, health systems, and a large health insurer.
