Great question with a number of answers, some of which might amaze you. Let's keep it simple: hire "A" team members. Period. There was a [at least one] blog post about how hiring "B" or "C" devs would destroy a startup within weeks. Same of any team. I love the expression, "Close enough for Rock & Roll", but that never works for hiring talent. And, if you don't know, every position is a 'talent' position in a startup. Sure, all the comments you have ever read about teaching and demanding team members pull their own weight, etc. are valuable. But start at the beginning. Plus, know that you cannot instill knowledge into others... they must seek it, consume it, and apply it for themselves. Final note for startups: hiring amazing talent from established firms is a huge challenge. Can they perform when there is no budget or assistants to do the work? Communicate what we call in the military, "Commanders Intent" and let the "A" players figure out the details.
