Insulet Corporation
A maker of the Omnipod, a tubeless, wearable insulin pump worn on the skin that lets people with diabetes manage their insulin without daily injections or tubing. The company was founded in 2000 after co-founder John Brooks' young son was diagnosed with type 1 diabetes, and its name blends "insulin" and "let." Legend has it Brooks first sketched the device's design on a napkin aboard an airplane.
