At Sprinter Health, we’re tackling one of healthcare’s biggest challenges: reaching patients who have fallen through the cracks of our healthcare system. With a boots-on-the-ground clinician network and the tech platform to solve this problem at scale, we bring critical preventive care to folks who are otherwise not getting it, whether due to disability, socioeconomics, transportation insecurity, or simply not getting around to it. We believe that access to healthcare shouldn’t be so hard, and by making it easier for folks to get the diagnostics and preventive care they need, we can halt the growing tide of disease and healthcare costs in America. Since launching in 2021, we're now live across 15+ states, covering over 60% of the US population and partnering with 6 of the 10 largest U.S. health plans.
