We are a team dedicated to helping people with diabetes live life while effortlessly managing their diabetes.

In June 2011, Yogen Dalal, Sundeep Madra, and Chamath Palihapitiya conceived the idea behind Glooko because each one of them was touched by diabetes in a meaningful way. Since then Glooko has become an innovative Silicon Valley company that delivers a mobile and cloud based, diabetes & chronic disease management system. We strive to improve health outcomes for people with diabetes and reduce the costs associated with diabetes population management. Glooko is dedicated to bringing innovation to diabetes management around the world.
