GeekOut was started two years ago by ZeroTurnaround and focuses on ideas and communication rather than the quantity of talks and pitches. Our only goal for the conference is to have each attendee learn two new ideas and meet two new people.

In order to keep the conference very focused we have hand selected and invited each one of the companies below for their contribution to the industry and their great products.
