Healthcare · Profile from Healthcare Research Companion

Dexcom, Inc.

The San Diego device maker that turned continuous glucose monitoring (CGM) from an inaccurate, fingerstick-dependent research tool into a prescribed, factory-calibrated sensor worn by millions. It built one of medtech's best recurring-revenue franchises on a 10–15-day disposable sensor. Along the way it won the regulatory and reimbursement fights that made CGM a standard of care for insulin users. It then fought Abbott's cheaper FreeStyle Libre for the mass market, launched the first over-the-counter CGM (Stelo, 2024), and in 2025 faced an FDA warning letter and accuracy complaints over its flagship G7.
