Company: BuzzFeed
Position: Founder

Jonah Peretti, the all-knowing Oz of BuzzFeed, is what The New York Times once referred to as a "viral marketing hot dog." And it's true, he knows his stuff. Just think about this: Peretti founded BuzzFeed after he helped found The Huffington Post. And as BuzzFeed continues to grow, Peretti's legend will only embolden.
