Obviously, this is a subjective question with many answers. However one clear marker is expert sales ability. Anyone involved in business for a while will know that there is a clear demarcation between average sales ability and superstar sales ability. The best sales people are not just a little bit better than the average, but multiple times better. Someone with this skill level can sell anything to anyone, including of course a piece of their company to the VC. The most delicious part is that at that level, this fancy decision tree is irrelevant; it's the sales expert who is selecting the VC, not the other way around.
