Inc.com has published their annual “30 Under 30″ online article on the country’s top young entrepreneurs. An interesting feature is T-shirt apparel company — The Hundreds.

What started as a blog and a simple T-shirt line produced by two law school classmates has become The Hundreds — a worldwide skateboarder lifestyle and apparel brand with an online magazine that attracts more than 1 million unique visitors a month. Kim and Shenassafar are the company’s sole owners, and they credit much of their success to their independence. “We’re not a corporate clothing company trying to sell down to you,” Kim says. “We’re ringing you up and sweeping the floors, and then going back to running a 30-person company. Our customers relate to it because we’re on their level.” Revenue is expected to hit $4 million in 2008.
