Jenn Hyman got the idea for Rent the Runway in 2008, after she watched her sister overspend on a new dress rather than wear an old one to a party. Jenn and her business partner built a web site where women could rent designer dresses for a fraction of the retail price.

Despite these challenges, Rent The Runway now rents dresses to nearly six million women and has an annual revenue of $100 million.
