DexCom, Inc. DXCM

Company Overview

DexCom, Inc. is a medical device company specializing in continuous glucose monitoring (CGM) systems for people with diabetes and related metabolic conditions. The company operates within the medical devices, digital health, and diabetes care industries, with a core focus on real-time glucose sensing technologies that reduce the need for fingerstick testing. DexCom’s products are primarily used by individuals with Type 1 diabetes and insulin-dependent Type 2 diabetes, as well as by healthcare providers who manage chronic glycemic conditions.

DexCom’s primary revenue drivers are its CGM systems, including sensors, transmitters, and receivers, supported by mobile software platforms that integrate with smartphones, insulin pumps, and digital health ecosystems. The company is widely recognized for its accuracy, ease of use, and interoperability with insulin delivery devices, which provides a strategic advantage in both clinical adoption and patient retention. Founded in 1999, DexCom initially focused on short-term glucose sensors for hospitals before transitioning to long-term wearable CGM systems, a shift that established the company as a leading independent CGM manufacturer globally.
