I am a regular genius at Facilitating. However, if you really want to amp the game to a new level, get a possible Funding Source or Investor to do it. It will really turn up the burner on everything.
What you want, is a good collision between Problems that are worth resolving (given your skills, abilities and interests), Market knowledge of the Value Propositions and for everyone to bring their "A" game to the table.
It would produce very substantial results. I would like to hear how it goes.
We can also talk more if you want.
