Rainfall Health, the U.S.-based digital health startup focused on respiratory care management and patient-centric treatment solutions, has raised $15 million in a Series A funding round to accelerate product development, enhance clinical integrations, and expand commercial adoption across healthcare systems and provider networks. The funding highlights rising investor confidence in tech-enabled care models that improve patient outcomes and streamline chronic respiratory disease management. The Series A round was led by Section 32, with participation from DCVC (Data Collective), Lux Capital, and other strategic investors who recognise Rainfall Health’s mission to deliver personalised respiratory care pathways powered by predictive analytics and digital monitoring tools. The capital will be used to grow the Rainfall Health team, invest in technology enhancements, and strengthen partnerships with clinicians and payers to improve access and quality of care. Rainfall Health’s platform combines real-time data capture, AI-driven insights, and patient engagement modules to enhance clinical decision support, optimise treatment adherence, and reduce hospital readmissions for conditions such as asthma, COPD, and other chronic lung diseases. The company says the new funding will support expansion into new healthcare markets and accelerate research collaborations with leading institutions. Rainfall Health is headquartered in San Francisco, United States, where it continues to deepen its footprint in digital respiratory care and connected health solutions.
