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?
Sam Corcos is a four-time founder and the co-founder and former CEO of Levels Health, a $300M metabolic health company that pairs continuous glucose monitors with a software layer to help people understand how food affects their blood sugar. He co-founded CarDash (Y Combinator S17, acquired 2020), Sightline Maps, and LearnPhoenix before building Levels into a category-defining health company with $67M raised from a16z and a community of 1,400+ member-investors. In 2025, he joined the Department of Government Efficiency (DOGE) and was appointed U.S. Treasury Chief Information Officer. He is also known for extreme minimalism (one pair of pants, one backpack), tracking time in 15-minute increments, and hosting 100+ intellectual salon dinners in New York and San Francisco.
