Signos

Signos is a metabolic health technology company founded by Sharam Fouladgar-Mercer and Bill Tancer that pairs a continuous glucose monitor (CGM) sensor with an AI-powered mobile app to help people understand their individual metabolic responses to food and make data-driven lifestyle changes for weight management. In August 2025 Signos received FDA clearance as the first over-the-counter glucose monitoring system for weight loss, making it available without a prescription to adults not on insulin. The platform integrates with the Dexcom Stelo sensor, Apple Health, Google Health Connect, smartwatches and smart scales, delivers real-time glucose insights, personalized meal and movement recommendations, registered-dietitian support, and daily and weekly metabolism scores, with optional GLP-1 medication access through partner healthcare providers. Signos was surfaced as a portfolio company of GV (Google Ventures). It is a consumer-facing product and does not currently publish a developer API, SDK, or developer portal.

Signos is profiled on the APIs.io network. Tagged areas include Company, Consumer, Health, Digital Health, and Metabolic Health.

Signos’ developer surface includes pricing, engineering blog, support, and 4 more developer resources.
