Trigence replaces its CEO and President

It seems that the application virtualization startup Trigence isn’t satisfied with its leadership team built so far as it continues to hire (or replace) executives:

And now the company replaces its former CEO and President David Roth with Greg O’Connor:

O’Connor joins Trigence from Progress Software, where he was President of Sonic Software. Greg grew the company from concept to 350 people.

O’Connor joined Progress Software Corporation in 1992. O’Connor oversaw the development, strategy and marketing of Progress® WebSpeed®, an HTML-based development tool and transaction server first introduced in 1996. Additionally, O’Connor was responsible for the introduction of Progress® Apptivity™, a Java application server and integrated development environment for developing and deploying Web-based business applications.

Roth was appointed in April 2005 and he’s now working at his own consulting firm.
