Online marketplace
Chief creative officer: Robert Kalin, 28
Etsy is a digital marketplace for buyers and sellers of handmade goods ranging from robots to rocking horses. The idea is "to empower small businesses and keep the big guys out," says Kalin, the company's founder. Etsy has attracted 200,000 sellers from 100 countries and expects to handle $100 million in transactions this year. It charges 20¢ for each listing, and sellers who want to showcase their wares can pay an additional $7 to $15 a day for advertising. Etsy also takes 3.5% of the price of every item sold.
