Company: NineSigma Inc., Cleveland-based operators of an online marketplace for technology buyers
How It Helps: NineSigma contracts with clients who need new product ideas, concepts, technologies and solutions to specific problems. It then posts the problems on its online marketplace, where inventors can propose their ideas. "Basically, [the inventors] send back a two-page outline of who they are, what they do and their relevance to the problem," says president and CEO Paul Stiros. At that stage, no confidential IP information is passed on--but if it's useful to the clients, a deal can be made directly between the inventors and the companies.
Cost: Nothing for inventors; the clients pay to use the service.
