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 multichannel AI agents automate complex workflows end-to-end, freeing staff to focus on patient care.

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 are an in-person company based in New York. We've raised $5.3M from Accel, Y Combinator, Sequoia (scout), and founders of Ophelia, Medallion, Counsel, Elemy, and Sana.

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.

Join us as we transform healthcare communication. We're creating a future where patients receive faster resolutions, staff are happier, and providers have more time for what matters most: patient care.

About Clarion

At Clarion, we're rebuilding how healthcare communicates in the age of AI. Today, clinics miss 30-40% of patient calls while staff drowns in administrative tasks. We believe AI agents should handle these workflows—scheduling, billing, prescription refills—so healthcare teams can focus on actual patient care.

We're building the communication infrastructure that modern healthcare desperately needs. Our AI agents don't just answer calls; they complete entire workflows end-to-end, giving providers back their time and ensuring patients never go unheard. We've already handled hundreds of thousands of patient interactions across virtual care companies, health systems, and a $5B health insurance company.

Founded by a Stanford/Harvard-trained physician who built Two Chairs and Ophelia, and an ex-Amazon Alexa engineer who led AI/ML at Salesforce, we uniquely understand both the clinical and technical challenges of transforming healthcare communication.

We've raised $5.4M from Accel, Y Combinator, Sequoia (scout), and healthcare founders from Ophelia, Medallion, and Counsel Health. We're an in-person team based in New York, moving fast to ensure no patient call goes unanswered.
