The idea I have is to set up a collectively funded food bank/food truck that can provide one free meal a day to anyone in the city who needs it (trying to eliminate the hunger problem here in America), to keep contributions and business running, I incentivize the investors/philanthropists by giving them a partial ownership in the business via a token.
This part I still can't understand. Your business, as you called, is actually charity as people donate to your food bank/food truck right? How you keep 'contributions and business running' when you're relying on donation and from that, partial ownership in the business to investors for shares of your business is enough to convince them of profit? Are you going to steal a part of the donation to keep as your profit?
