However, the road to success wasn't always easy; he was turned down by 27 banks for a loan and had to remortgage his mother's house twice during FUBU's early days. His big break came when he convinced LL Cool J, an old neighborhood friend, to wear a FUBU T-shirt for a promotional campaign.

Lori Greiner started her career selling jewelry storage organizers. One patent, which she later sold the product at JCPenney, Home Shopping Network, and other channels, became a huge hit and made the businesswoman her first million. Within three years, she was making more than $10million.
