Twenty-Five U.S. Entrepreneurs Ages 25 and Under

Twenty-Five U.S. Entrepreneurs Ages 25 and Under

This summer, BusinessWeek set out on its fifth annual search to find the country's most promising young entrepreneurs. As in previous years, we asked readers to nominate candidates ages 25 and under running their own companies. After the call for nominations ended in August, our staff whittled the batch down to 25 impressive businesses. To read profiles of the finalists and vote for the business you feel holds the most promise, click on. We'll announce the top vote-getters on Nov. 9.

Note: Revenues and traffic numbers are self-reported. To be considered, founders had to be 25 or under when the nomination form was posted in late June.
