"well, I don't know anything about construction but I can draw pictures of buildings" That's called an architect... and they do start companies that produce buildings. Just like I'm sure there are a lot of construction guys that hire an architect. The idea does not necessarily have to be tightly coupled with the execution. It can certainly make things easier and the road to startup hell is paved with people who had an idea without any concept of how it can/should be implemented - but they can still be successful under the right conditions.
