Rainfall Health provides a software platform that automates the collection, standardization, and reporting of patient outcomes so hospitals can comply with CMS’s new Transforming Episode Accountability Model (TEAM). Its AI engine guides providers through regulatory requirements, aligns clinical workflows with value-based metrics, and carries a verifiable RAIN Compliant designation adopted by hospitals, payers, and clinical partners. The product is already live in several hospitals and medical groups and targets the 742 U.S. health systems now mandated to participate in TEAM. By enabling consistent check-ins, clear patient instructions, and clinician follow-ups, Rainfall aims to help hospitals capture up to 20% additional revenue on high-spend surgical episodes. The company plans to use new capital to expand its AI engineering staff and build a world-class customer support organization to accelerate nationwide deployments. Headquartered in San Francisco, Rainfall Health continues to pursue its mission of improving access to high-quality, outcome-based care across geographic regions.
