DXCM

Dexcom, Inc.

A maker of continuous glucose monitors that let people with diabetes track their blood sugar in real time without routine fingersticks, with products like the G6, G7, and Stelo. Founded in 1999 in San Diego, the company grew out of research at the University of Wisconsin and launched its first FDA-approved sensor in 2006. Its Stelo was the first continuous glucose monitor cleared for over-the-counter sale in the US, no prescription needed.
