In 1990, Tunnell left Dynamix to start Jeff Tunnell Productions. Tunnell would go on to create famous brands such as The Incredible Machine, Trophy Bass, and the 3-D Ultra Pinball series while at Jeff Tunnell Productions. These products were some of the most successful retail products to be published by Dynamix.
In 1995, Tunnell returned to Dynamix in a leadership role.
In 2007, GarageGames was acquired by InterActiveCorp, the media conglomerate founded by Barry Diller. Tunnell remained on as Chief Creative Officer of GarageGames. Tunnell was a contributor behind the vision of the original InstantAction distribution platform.
