I would suggest existing programs and community organizations already support this kind of goal. The St Giles Trust in the U.K. already existed prior to the program, and this partnership allowed it to scale up. I don't think anyone needs to invent new organizations. I think the better approach would be to find what we know to be existing, effective programs and give them an opportunity to scale up through this mechanism.
