Steinberg had previously worked four years at BuzzFeed, where he led the site alongside Jonah Peretti. He was the fifteenth employee and has helped grow revenue to $60 million.
His departure was surrounded by speculation, with some talking about vested shares and others suggesting disagreements over salary. The most well-reported rumor speculates that Steinberg left after Peretti refused to sell BuzzFeed to Disney earlier this year.
Steinberg tweeted this today:
