I'm a single man non-technical founder. Its a lean startup, and we're doing some killer customer development.
Give a Google of "talent triangle". I have found that the majority of successful start ups have people with: Business acumen, domain knowledge and operational experience. E.g. (reverse order) someone who understands how to build it, someone who understands what customers want and someone who can help execute. A hacker, a designer and a hustler.
Of those three corners in the talent triangle what are you weakest on? Let that guide you.
