Superpower is a San Francisco preventive-health startup building what it calls the world's first health super app. Members get annual lab testing analyzing more than 100 biomarkers across 17 body systems, far more comprehensive than a standard physical, plus text access to a concierge physician team and an AI health advisor that explains results and recommends optimization strategies. The platform aggregates biomarkers into body-system scores and a biological-age estimate, turning episodic checkups into continuous monitoring. In April 2025 Superpower raised a $30M Series A led by Forerunner Ventures at a valuation above $300M, with backers including Bond, Susa Ventures, Winklevoss Capital, Day One Ventures, and high-profile angels. The company targets consumers who want proactive, data-driven health management at a flat annual price.
