Signos, the company behind the first FDA-cleared, over-the-counter glucose monitoring system for weight management, announced a $20 million funding round with investment from GV (Google Ventures), Dexcom, and Blue Cross Blue Shield of Alabama. As part of the partnership with Dexcom, Signos will be available for purchase on Stelo.com, Dexcom's direct-to-consumer CGM website, making it easier for people to find and access the Signos system.
