Post-acute agencies lose up to 15% of revenue each year to denials, non-compliant documentation, and delayed payments. Most treat it as a cost of doing business. Instead of waiting weeks for rejections and appealing claims one by one, Claim Health flags issues in real-time and automates claim corrections and appeals—before revenue is lost. While working with healthcare providers, we found most denials stem from small, preventable documentation errors. As payor requirements grow increasingly complex and fragmented, billing has become a manual, error-prone process. Claim Health closes the loop between documentation and billing outcomes—using AI to detect issues, automate workflows, and recover thousands in missed revenue each week. Kevin and JJ bring nearly a decade of experience building and scaling healthtech companies. At Dandy, JJ was a founding engineer and Kevin was the first GTM hire; together they helped grow the business from 0 to $150M+ ARR. At Perry (now Jolly), JJ led engineering and Kevin was Head of Sales, driving the company through a $16.5M Series A led by Tesla’s former CFO. In under three weeks since incorporation, we've launched with three agencies and are in early discussions with large U.S. health systems. Post-acute care is a $400B market with over $20B in annual revenue leakage due to broken billing workflows. Claim Health is fixing that—starting with denials, and expanding into the full revenue cycle stack.

Clarion is building the most advanced AI communication layer for healthcare. Our AI agents handle the overwhelming volume of calls and messages that clinics face daily—from scheduling to billing to prescription refills—freeing staff to focus on patient care. We're an in-person company based in New York. Today, clinics miss 30-40% of inbound calls due to staffing shortages. We're solving this by automating complex workflows end-to-end, already serving tens of thousands of patients monthly across virtual care companies, health systems, and a $5B health insurance company. We've raised $5.4M from Accel, Y Combinator, Sequoia (scout), and healthcare founders from Ophelia, Medallion, and Counsel Health. Our founders bring both clinical and technical expertise—our CEO Ryan is a Stanford/Harvard-trained physician who was on the founding teams of Two Chairs and Ophelia, while our CTO Jeffrey built voice AI at Amazon Alexa and led AI/ML teams at Salesforce. Join us as we transform healthcare communication—creating a future where patients get faster resolutions and providers reclaim time for what matters most.
