This detailed history of Open Options in Waterloo, ON mentions Tom Mitchell, CEO. I worked with him briefly at Imperial Oil back in the mid 70s. Article fails to mention Dr Gerry Sullivan, a cofounder of Open Options, who was in my engineering class at U of Waterloo. I would have really enjoyed working with these guys.
