The founding/management team is one of the critical areas investors look at in a startup. Usually the team is more important than the idea/product.
Investors like to see a proven track record of previous successes. But what if this is your first startup? How can a first time entrepreneur demonstrate his ability to execute if he doesn't have a prior business he can point to? What strategies can a first time entrepreneur follow to overcome this?
The immediate thing that comes to mind is talking about your successes while working for a previous employer, but that seems a bit weak to me. Is there a better way to answer this question?
