Health tech startup Signos has secured $20 million in its latest funding round, solidifying its position in the burgeoning GLP-1 weight loss market and deepening its strategic alliance with medical device leader Dexcom. The investment, which saw participation from Google Ventures, Dexcom, and Blue Cross Blue Shield of Alabama, also ushers in a new distribution agreement to feature Signos’ subscription plans on Dexcom’s direct-to-consumer platform.
“Dexcom’s investment truly underscores a shared vision for the future of glucose biosensing, extending far beyond traditional diabetes management,” stated Sharam Fouladgar-Mercer, CEO of Signos, in an interview. “Their biosensor provides invaluable real-time glucose data, which we then transform into actionable insights and personalized guidance for users.”
Signos is at the forefront with its artificial intelligence-powered glucose monitoring system, designed to facilitate healthy weight loss. This innovative system was the first of its kind to receive FDA clearance in 2025. It leverages Dexcom’s widely available continuous glucose monitors to track how an individual’s daily lifestyle choices—from dietary selections and sleep patterns to stress levels—impact their glucose readings. The Signos platform then synthesizes this data to offer tailored recommendations aimed at cultivating healthier habits.
“Our aim is to demystify personal metabolic health,” Fouladgar-Mercer explained. “We’re not asking users to become statistical experts to understand their bodies. Instead, we’re translating complex glucose insights into practical, easy-to-follow recommendations. Our pattern recognition technology is specifically designed to support users in building sustainable healthy habits and achieving long-term weight management.” The company declined to disclose its valuation following this funding round.
The infusion of capital will also fuel the expansion of Signos’ predictive AI capabilities. A key development includes enhanced meal scoring, where the AI analyzes a user’s data to predict and alert them about potential glucose spikes from specific foods before they are consumed. This proactive approach aims to empower users with knowledge to make more informed dietary decisions.
“The true potential of AI lies in its ability to translate biological signals into practical, user-friendly guidance,” Fouladgar-Mercer emphasized. “Imagine taking a photo of your meal. Our AI can identify the food, estimate macronutrients, and correlate it with your activity levels. More critically, it then analyzes your body’s real-time response, providing immediate feedback to drive positive behavioral change.”
Signos positions its service as a versatile solution, suitable for individuals seeking to complement their GLP-1 drug treatments, such as Novo Nordisk’s Wegovy and Eli Lilly’s Zepbound, or as a standalone weight management program. The growing demand for these GLP-1 medications, which have shown remarkable efficacy in weight loss, highlights a significant market opportunity. Data indicates that nearly 74% of Americans are classified as obese or overweight, and financial projections from JP Morgan forecast that the number of Americans utilizing GLP-1 therapies could more than double from 2025 to approximately 25 million by 2030.
While Signos refrains from disclosing specific revenue or user acquisition figures, Fouladgar-Mercer reported a tenfold increase in both revenue and user base over the past six months. He also noted that “tens of thousands” of individuals have participated in the company’s clinical studies.
“Simply tracking output metrics like steps or heart rate offers limited insight,” Fouladgar-Mercer concluded. “Without the ability to monitor metabolic input and the subsequent biological response, our capacity to truly assist people in achieving their health goals is significantly constrained. Signos bridges this gap, providing a holistic view for more effective interventions.”
