UserVoice makes it easy for companies to collect user feedback in an organized, social way. How many times have you received the same feature request over weeks or months, only to lose it in the feature prioritization shuffle?
UserVoice lets users discuss features and bugs but submit their own, and rate (vote for) features that others have suggested. It's leveraging the power of the crowd to do feature prioritization for the product. Of course, this is still customer feedback and needs to be evaluated alongside product portfolio and market strategy, but its certainly much better than anything else I've seen.
UserVoice started off selling its service to start-ups but has expanded to big clients such as Intuit Inc., the National Aeronautics and Space Administration, Facebook Inc., Nokia Corp., Nielsen Co., Genetech Inc., Blackbaud Inc. and University of Wisconsin. - WSJ Online
Generally the "developer tools" market isn't sexy or that profitable unless you're catering to large companies, but this seems targeted to organized marketing and products groups rather than small startup software development groups where the technology is the innovation. This is funded by the ubiquitous Dave McClure and the Founders Fund, who see this problem all the time from the boardroom - what do customers really want and how can we really be sure? Credible, first hand data would certainly help VC's call BS on those CEOs hiding behind the curtain of personal bias.
I'll use UserVoice on my next web project and see how we get on.
