What worked?  What needed improvement?  What motivated contestants and what got community members excited?  We've captured insights on the ClimateSpark Social Venture Challenge in a final report that, in the spirit of open collaboration, we are sharing widely.  We hope these findings will be useful to anyone interested in open innovation and crowd sourcing.  Meanwhile, they are already informing our thinking about future Challenges.  Have an idea for a challenge or interested in using the ClimateSpark platform for your own challenge?  We'd love to talk - contact Mary Pickering to start the conversation.
