What happens when you brainstorm with 1000s of people? You can find great ideas (and plans, prototypes, partners and people). We call it crowdstorming. But organizing 1000s of people introduces some new challenges. We studied 100s of projects to understand what works. This deck is what we use in our workshops to introduce the main crowdstorming concepts. It is also the outline of our book, Crowdstorm. Enjoy Shaun, Pete and Bastian.
