Irhythm Holdings, Inc.
A digital healthcare company that makes wearable heart monitors, best known for its Zio patch — a small peel-and-stick sensor patients wear for up to two weeks, including in the shower, to continuously record their heartbeat while AI software helps spot irregular rhythms. A cardiologist, Dr. Uday Kumar, founded it in 2006 after struggling with bulky Holter monitors that missed intermittent heart problems. The Zio patch, worn comfortably during normal daily life, was designed to be water-resistant so patients could shower and exercise while being monitored.
