Fogbugz, if the first version even existed in 2000, was not a SaaS. Nor was Jira, by the way.

Both products were initially once-off purchases that you had to install and run on your own infrastructure, and with new, major versions packed with new features that you had to buy if you wanted, but could ignore if you didn’t.

The move to a SaaS model came years later for both products.
