Signos is a San Francisco Bay Area digital health company pairing a continuous glucose monitor with an AI-driven app to help non-diabetic adults lose weight and improve metabolic health through real-time, personalized feedback on food, sleep, stress and exercise.
Sharam Fouladgar-Mercer is the Co-Founder and CEO of Signos, the company behind the first FDA-cleared over-the-counter glucose monitoring system for weight management. A Princeton computer science graduate and Harvard MBA, he played NCAA Division I ice hockey before building a career spanning VC at Sierra and Shasta Ventures, co-founding PR tech company AirPR (later Onclusive), and ultimately creating Signos in 2018 after his own lifelong struggle with weight and the death of his diabetic grandmother inspired him to ask: why wait until someone is sick to give them metabolic data?
