Mophie makes cases, splitters, arms band, and clips for the iPod. The iPod accessory market may be crowded these days, but Kaufman's goal is to turn Mophie into a community-based product-development company that will solicit ideas for all kinds of new products -- not just iPod add-ons -- from a 50,000 member online user base. He's got $2 million in venture capital and a former top exec from Burton Snowboard on board to help him do it. Revenue is expected to hit $5 million this year.
