Clarion is building the most advanced AI communication layer for healthcare, enabling clinics overwhelmed by routine calls and messages to finally come up for air. Our AI agents automate complex workflows end-to-end, freeing staff to focus on patient care. We are an in-person company based in New York. The reality of healthcare today: clinics miss 30-40% of inbound calls due to staffing shortages, while patients struggle to connect with providers. We've built AI agents that handle scheduling, billing, prescription refills, and more—serving tens of thousands of patients monthly. We're growing rapidly, serving dozens of customers including virtual care companies, outpatient health systems, and a $5B publicly traded health insurance company. With demand surging and revenue quadrupling in recent months, we're scaling our team. We've raised $5.3M and are backed by Accel , Y Combinator , Sequoia (scout), as well as the founders of Ophelia, Medallion, Counsel Health, Elemy, Sana, and more. Our clinician-led founding team combines healthcare operations expertise with technical excellence. Dr. Ryan Gallagher, our CEO, is a Stanford/Harvard-trained physician from the founding teams of Two Chairs and Ophelia (YC W20). Jeffrey Lamothe, our CTO, worked on voice AI at Amazon Alexa and led AI/ML projects at Salesforce and Citi's AI lab.
