Upperline Health was founded to provide the highest quality foot care to patients in need through a highly skilled and compassionate team. As one of the fastest-growing healthcare providers in the United States, we are building out a network of top podiatry practices across the country to partner with health plans and community providers to deliver comprehensive foot care in a consistent and high-quality manner. Upperline Health provides an extra layer of care to patients with a diabetic foot ulcer (DFU) or patients at risk of developing a DFU, and intervenes with the appropriate care earlier. Each year, hundreds of thousands of Americans will lose limbs due to diabetes. Tragically, studies and research show that many of these amputations and the resulting decline in quality of life could have been prevented with proper foot care. We founded Upperline Health to bring together podiatry practices to address this gap in health care and to bring high-quality care to patients who need it most.

Our roots are in one of America’s great entrepreneurial success stories. Fidelity Investments was founded in 1946 and grew from a single mutual fund into one of the largest asset management firms in the world, with over $2 trillion in assets under management. For the last forty years, our venture capital group has had the privilege of backing other great entrepreneurs as they built ground-breaking companies in technology and life sciences, including Atari, MCI, ROLM Corp., Alibaba, Ironwood Pharmaceuticals, and Ultragenyx. Today our funds are larger and more global, but our teams are still small and local. We stay true to our entrepreneurial roots. In the US and Europe, we are F-Prime Capital investing in healthcare (formerly Fidelity Biosciences) and in technology (formerly part of Devonshire Investors). In other geographies, our sister fund is called Eight Roads (formerly Fidelity Growth Partners), with investment teams in London, Shanghai, Beijing, Hong Kong, Tokyo, and Mumbai. Together we bring a world of insight, domain expertise and relationships to support our entrepreneurs. Without the pressure of fundraising from outside investors, we focus all of our time finding and helping great entrepreneurs build important companies.
