Propeller Health has closed $21.5 million in Series C financing, which includes 3M Ventures as a new investor.

Propeller has a digitally-guided therapy platform that integrates information across the care continuum and offers products for patients. Other options include schedule recommendations, automated clinical outreach and recommendations for care manager outreach.

“We aim to make today’s treatments more accessible, personal, powerful and convenient for each person who uses them, and enable physicians to measure, analyze and act to help their patients,” said David Van Sickle, CEO of Propeller. “Our goal is to connect and guide these patient-physician teams to find the right path of therapy for each individual.”

“Propeller is bringing a smarter, digitally-guided approach to the management of respiratory disease, an area of significant economic burden to healthcare systems,” said Rajeev Dadoo, Partner at S.R. One, Limited. “The company uniquely combines unprecedented real world evidence about how patients take their medications, with a deep understanding of what people want from their respiratory treatment.”
