Founded in 2009, FanDuel is a web-based fantasy sports premium game and the undisputed leader in the daily fantasy sports concept. The model consists of traditional season-long fantasy sports leagues being compressed into a daily, and occasionally weekly, game.

It has over a million paid active users, paid out $560 million to winners in 2014 and is set to increase that to $2 billion in 2015.
