I think as a Startup you should spend 90% of your time on refining and validating the Problem Definition. Do as much as you can of that activity without even creating a single line of code. Since most probably you are solving a human problem, you should interact with as many humans as possible.
Lets be honest, unless you are creating a rocket or some really cool new technology, most Web Services/Apps can be implemented by anyone. YOUR job as Startup is not to reinvent the wheel for the solutions but live and breath the problem definition. After all it will be much cheaper and faster to fail if you have not built the product yet.
