So you definitely need someone with 'hustle' to go find a market, and you definitely need a coder to build the product. I'd argue that having the same person do both of these things means that there is (a) a higher probability that the solution can actually be implemented as software and (b) that the software will actually work as expected by the customers. (Zed, I suspect that the Product Management role you mentioned might encapsulate these skills.)
