Kevin A. Plank is an American billionaire businessman and philanthropist. Plank is the founder and chairman of Under Armour, a manufacturer of sportswear, footwear and accessories, based in Baltimore, Maryland.
Noticing his football teammates’ sweat-soaked shirts, Plank came up with a lightweight, sweat-wicking shirt using fabrics from women’s undergarments.
In the mid 1990s he sold his first shirts from his grandmother’s basement, exaggerating to early customers to make the company sound bigger.
Plank, who is Under Armour’s CEO, took the company public 2005; he owns a nearly 16% stake.
He is building a 4 million-square-foot headquarters for Under Armour in Baltimore as part of a larger development called Port Covington.
