Startup Idea : Startup collaboration

Ideaswatch is great for generating ideas, but what about once the idea is accepted? Maybe Ideaswatch already does this, but offer a place for people to initiate a startup together and build their team. There would be a private forum in which all team members can view, there can be a to do list, vision statement, and more - all private and only for the viewing of the team. They can elect what is public and people can invest into their startup similar to kickstarter but without a goal, or with a goal. For example, say one of these ideas here goes to build phase, I see it and I'm not on the team, I can chip in $X to help them out. They can offer gifts like kickstarter too. This would be the team's hub for all ideas, funding, production and marketing.
