An interesting cover story in the June 2008 issue of Inc. magazine names a T-shirt company called Threadless “the most innovative small company in America.” Why? Chicago-based Threadless uses “crowdsourcing” to choose its T-shirt designs, with participants in its online community submitting designs in the company’s competitions and then voting to choose the winning ones. The result: A very profitable company whose growth rate was more than 200% in 2007. As Inc. notes, Threadless was featured in a 2006 article in the MIT Sloan Management Review .
