The site caters to any cocktail-napkin Thomas Edison. Inventors pay $99 to submit an idea. Each week, the community rates the new batch. Among the ideas that come across the site in any given week, you might vote for, let's say, three: An RFID dog bowl that keeps other pets from chomping Rover’s kibble; a double-sided USB stick, for separating work and personal files; and a credit card-shaped holder that stores a half-dozen sim cards, for example. You pan the underarm maxipads and the dog mints, among other things.

Best outcome for you, the inventor: Your idea gets produced. Worst outcome: free advice and feedback.

At best, the prototype would have been junked at a flea market,” Kaufman says. “But it ended up being sold in 25 countries.” And that’s when Kaufman realized that he was more interested in developing products—and in helping people like himself, when he was 18. So he sold Mophie, and built a platform for idea sharing, called Kluster.
