Candid Health raised $120 million for an AI platform aimed at revenue cycle management (RCM), signaling continued investor appetite for automation in healthcare operations. The Series D round was led by Sixth Street Growth and included participation from Oak HC/FT, 8VC, and Y Combinator. The financing supports further deployment and product development for AI-assisted workflows that target coding, claims processing, and related functions tied to reimbursement. In an industry where reimbursement mechanics are a persistent bottleneck for biopharma and provider ecosystems, RCM tools are increasingly positioned as infrastructure software. For the broader healthcare tech stack, the round adds momentum to vendors that promise faster turnaround and reduced administrative friction—an area that can influence access to therapies and the financial health of delivery systems.
