Candid Health raised $120 million in a Series D round to expand its AI platform for revenue cycle management (RCM). The financing was led by Sixth Street Growth, with participation from Oak HC/FT, 8VC and Y Combinator. While RCM sits outside traditional drug development, the funding signals continued investor appetite for AI systems that reduce administrative friction in healthcare delivery—an area that can influence adoption speed for digital health and care delivery workflows. — Key takeaway: the round underscores that healthcare AI infrastructure remains a funding priority, even as biotech pricing and access concerns dominate the industry agenda.
