Nick Hanauer has founded, cofounded or funded more than 30 companies across a range of industries. Among his many successes is aQuantive, which sold to Microsoft for $6.4 billion. He was the first non-family investor in Amazon.

At the same time, Hanauer -- a self-described "proud and unapologetic capitalist" -- has become a leading critic of modern economic policy. He warns plutocrats that "the pitchforks are coming," unless we do something about the growing gap between the rich and poor.

Hanauer has been featured in a variety of publications and is a frequent commentator on politics and economics in the media and on his podcast Pitchfork Economics. His opinion pieces have been featured in the New York Times, Bloomberg Business Week, The Atlantic and Democracy Journal, among others.
