At many startups, the biggest name is not actually an employee but a wizard behind the curtain. He could be a former startup founder, a C-Suite consultant, or even an investor. If we had our pick, we'd want: Kevin Plank, 39, Under Armour founder and bigtime supporter of entrepreneurs; Bill Campbell, 71, the former Columbia football skipper, Apple board member, and adviser to Google and others; and Mellody Hobson, 42, who sits on the board of Starbucks, Estée Lauder, and DreamWorks and brings sophistication and prestige.
