Nathan Gwilliam

Just 23 credits short of a bachelor's degree, CEO Nathan Gwilliam left BYU because his Internet company was growing so fast he didn't have time to do both.

Gwilliam wrote a business plan for a company called Adoption.com while at BYU. That was 10 years ago. Now the business, called Adoption Media, is the largest adoption organization in the world.

Gwilliam owns several companies. In 1999, after he had taken his company Today.com public, he lost it. He was 24 years old at the time.

"I lost over $11 million in one day," he said. "That was a really bad day."
