Backed by $50M+ from Bessemer, American Express, Felicis and Health Velocity Capital, they run two products: Marketplace: the leading dental procurement platform in the US, profitable since Q1 2026. RCM (Revenue Cycle Management): a new AI-native platform that automates insurance claims, follow-ups and payment posting. It’s moving from beta to full launch between late 2026 and Q1 2027, with patient payments and finance products next on the roadmap.
