Even at an event filled with wunderkind tech stars, Jess Lee stands out. Lee, 28, is a computer scientist and Google alum who went on to help run Polyvore, a popular (and profitable) website that lets users mix and match pictures from all over the web to create outfits that they can then purchase through Polyvore partners like Zappos.com. Raised in Hong Kong, Lee stayed in the U.S. after graduating from Stanford and joined Google's elite, two-year associate product manager program, which places brilliant kids in key jobs. She exhibited a rare ability to "take the lead in product design as well as product development," says LinkedIn senior vice president Deep Nishar, a former Googler. After four years working on Google Maps and other things, Lee joined three ex-Yahooers in 2008 to introduce Polyvore. "I fell in love with the prototype and was hopelessly addicted to it," she says. Now her job is to make sure fashionistas feel the same way.
