Here's a TL;DR I prepared ;) Open models for value creation work. Look at open source projects, Wikipedia, Kickstarter projects and many others. Lean Startups and Customer Development approaches are pretty open too and we are increasingly seeing open data and open, transparent support ... but how far can we go? Can we open up everything in a startup from idea generation to planning, discussions, financial and testing data? What would an "open source" business look like?
