In the early 1990s, Criswick studied space physics at York University, and while obtaining his Master's degree, he worked at an observatory in Utah.
In 1997, Criswick was contracted by Nortel Networks to source a web browser to work on a mobile device.
When he discovered there was nothing compatible on the market, he and colleague Bob Tennant began to build a browser.
Nortel agreed to fund the project, and by the end of 1997, Criswick and Tennant had decided to form their own company, Beduin Communications.
Some of them include Zucotto Wireless, Magmic, Top Shelf Distillers, and Upper Narrows Retreat.
