This kinda goes to what I was mentioning with long term vision and focus. I don't think anyone wants to work their ass off for the idea guy. I think it needs to be a community of doers not dreamers. It doesn't need to be super hierarchical or exclusive, but talk is cheap.

Have you participated in Open-Source projects? There is leadership: a few (2-3) the most active contributors. The thing is it's easier to find them if the project is Open-Source. And contributors can make sure in advance they like the project. E.g. I started contributing to someone else's project with lots of stars on GH. And after some period of time became its maintainer and the second leader. If I had to go through interviews first and all that stuff that hiring requires, I would never be there.

What problems does the idea solve?

I think there are lot of people that can contribute part time to a venture but don't want or can't contribute from a full time perspective.
