Executive Team


Mark Hogan

Chief Executive Officer

For nearly 30 years, Mark has built and managed some of the largest and most successful government sales organizations for the nation’s leading technology firms.

As the first Director of Civilian Agencies for Oracle, Mark helped ignite the success of one of the largest software companies in the country.

His career advanced as he directed federal and worldwide sales operations for established companies in document and records management, and culminated as SVP and General Manager of BEA Government Systems.

Mark grew BEA Government Systems’ revenue from less than $2 million to more than $148 million in less than three years. While running BEA Government Systems, Mark heard from hundreds of talented technology partners who desperately needed help in selling to the federal government and he formed GSS in 2003 to help those companies develop successful government sales programs.

Mark has served on a number of advisory boards as well as the Congressional Blue Ribbon Task Force on Aviation Safety, formed after the September 11, 2001 terrorist attacks. A recognized expert in selling to the government, he is a frequent speaker on the subject and a guest lecturer at the Robert H. Smith School of Business at the University of Maryland as well as Harvard Business School.

In addition to his extensive experience selling to the federal government and serving as a guest lecturer at business schools, he has devoted himself to helping veterans returning from service overseas. One of his proudest endeavors is his work as a pilot with the Veteran’s Airlift Command, an organization that pairs pilots with servicemen and women wounded who were in combat and need medical attention out of state.
