That is easy to say, but often you don't know exactly the right person with the right skill set at the time you need them. If you only work with people you have known for several years you are going to have a slow time growing your company.
If you don't have the skill set within your personal network of yourself plus possible cofounders to start the company, then this idea/company is not within your reach to execute effectively. Do something else.
I was referring to co-founders only in my comment about trust and track record. I agree that at some point you will have to bring people on board that you haven't known for that long, but then the risk is also a lot smaller since they won't be co-founders.
So you'll only bring on people with a proven track record of having multiple past exits? That severely limits your options... plus why would someone with multiple successful exits want to work with you?
