I have an idea for a billion dollar company in the space of health care. It's a bit similar to metamed but has much better business model. I'm at the moment not sure whether to persue it commercially. From an EA perspective I would also be happy if someone else builds the company.

At the moment I'm thinking about writing a longer document laying out the idea but don't know about the best venue for it. Are you aware of any competitons for ideas where money can be won by writing a document about health care innovation without having an startup working on the idea?
