I like this article, but there's another way of classifying that I also like: letter grades (remember those from school?) which uses hiring psychology a little more. In a successful startup, whom you hire makes or breaks you.
'A' players hire 'A' players.
'B' players hire 'C' players.
Independent of Revolutionary vs. Evolutionary, we have pure intelligence, education, and animal cunning. An 'A' player has all those, and moreover knows when a Revolutionary strategy is required, and when it's not.
A 'B' player tends to be Evolutionary, because it's safer, but occasionally he'll say "me, too!" to a Revolutionary if it seems to advance his career.
An 'A' player can recognize another one. That's all he or she wants to hire.
A 'B' player is bewildered and threatened by an 'A" player, and moreover, the 'A' player wants nothing to do with him. So he wants to hire someone who's safe and no threat to his tenuous position: the 'C' player.
After the startup is successful, the 'B' managers flood it with their resumes. They like a safe bet. Once they get in and start hiring their own, it's all over.
