United States onlyWellth is a pioneering digital health company.
Wellth is a fast-growing, growth-stage digital health company headquartered in Los Angeles. Our mission is to motivate people living with chronic conditions to make healthier choices, every single day.
We use behavioral economics, habit science and technology to motivate lasting behavior change in some of the highest need and most underserved populations in the US (Medicare and Medicaid), drastically changing their quality of life and health outcomes. We have demonstrated results with several large insurers and health systems (e.g. reducing hospitalizations by over 40%), and are now rapidly scaling. Our goal is to be the category leader in improving health outcomes for hard-to-engage populations. A key difference at Wellth compared to other digital health companies is that our users (Members) actually use Wellth every single day - think TikTok tier daily engagement (and data generation!).
But most importantly, our work quite literally saves lives by stabilizing chronic disease patients and preventing disease progression, hospitalization, and other bad outcomes. We are a mission-driven company where you work with incredible talent and see tangible differences directly from your impact.
