    Startech's story;

    StarTech.com was founded in 1985 by Paul Seed and Ken Kalopsis. Paul and Ken met while attending the University of Western Ontario, in London, Ontario in the early eighties. Originally known as StarTech Computer Accessories, the company had very humble beginnings as a "Visa Card" founded operation, manufacturing products such as computer dust covers in the basement of a house.

    The company has grown to become a global manufacturer of over 3000 products with operations in five continents but one thing hasn't changed: Startechs commitment to making our customers' jobs easier.

    Thanks Jordan for the reply, and going well beyond anything I would expect from a company helping it's customers. Most company employees would have simply looked at their catalog and said "if it's not here in our catalog we don't have it" So to say I was pleasantly surprised would be an understatement, as a matter of fact I think the way you personally handled my inquiry is a great example of what customer service should be about, and will be using this example at my next meeting with my employees. Keep up the good work, Compsource is very fortunate to have you on their team. Sincerely, Don / President Beauty and Health Institute Don Kruse
