Non-technical stuff like having a clue on how to actually make some money, maybe some domain expertise so you can actually solve a problem instead of just doing something cool? Yeah those can wait.
Hackers who dismiss the importance of being able to pull together and organize this type of work are just as bad as idea guys who think they can just get anybody to do this "really simple thing"..
There is a lot of nontechnical stuff to do in a startup but it doesn't make sense to start most of it until you actually have something working.
