I'm sure there are plenty more, but IDEO, Frog Design, and GOOD are really darn, uh... excellent at doing open innovation and crowdsourcing. Truth be told, I'm not entirely sure if I can call them excellent at this, since I don't know the actual outcomes yet. But here's some info on them:
OpenIDEO sources ideas from the crowd on how to make the world a better place:
Introduction to OpenIDEO / OpenIDEO.com from IDEO on Vimeo.
FrogMob solicits ethnographic data from the crowd to "gather a quick visual pulse on behaviors, trends and artifacts globally." It aims to give a rich visual description of how products are used globally.
GOOD gathers ideas and content for their magazine issues from the crowd on topics ranging from Work to New Orleans to Water. Fascinating what they come up with.
Who else does this well? I'd love to hear about the groundbreakers in this space that I'm surely not aware of. Thanks!
