What Is Signos?

Signos is the only company that combines a CGM with an AI-driven app to deliver real-time glucose monitoring for optimal health and weight management.

Signos translates an individual’s metabolic signals into timely recommendations for eating, exercise, and better health.

How Does Signos Work?

As members begin their Signos journeys, they log what they eat, allowing the Signos platform to learn each person’s glucose reaction to specific foods. Once calibrated, Signos uses that data to provide personalized nutrition suggestions, including which foods are best for each member, when to eat them, and when to exercise to bring glucose levels back within their optimal weight loss range.

Our story

Glucose Is the Key

Sharam's lifelong struggle with weight and fitness combined with a desire to understand his body brought him to the idea that glucose could be the ideal biometric to track. He took Bill—who tracked his weight via spreadsheets—out for pizza and they came up with the idea of creating a new, biodata-centric approach to weight loss.
