1. Marc Benioff
Marc Benioff isn't all talk. While he's not shy about taking jabs at the competition -- especially Oracle chief Larry Ellison, who helped groom him -- Benioff has the innovation chops to back up the bluster. He's taken Salesforce from a SaaS upstart to a cloud colossus in just over a decade and his new push into the social enterprise is altering the way global business, communication and collaboration happen. Benioff has a knack for catching onto trends well before they happen and tying them into Salesforce's ecosystem of cloud offerings. Benioff is out to prove that business software doesn't have to be boring.
