To provide best-in-class services and solutions essential to our customers


To become the most sought-after and respected management and technical services firm within our domain.


GS5 began operations on July 25, 2003, when four aspiring entrepreneurs signed the company’s operating agreement and pledged to provide “superior on-demand business solutions” in support of program and business management activities within the Department of Defense (DoD). Headquartered in Dumfries, Virginia (a HUBZone), GS5 experienced a modest beginning but persevered as one of the fastest-growing business management entities within the DoD community.

GS5 secured its first prime contract with the Defense Information Systems Agency’s (DISA’s) Global Command and Control System – Joint (GCCS-J) program in February 2004, just six months after the company’s formation.

GS5 leveraged its founders’ domain expertise in program and business management methods and management tool development to provide real solutions—not just a host of consultants’ recommendations, but functional products and finished technical solutions. The foundation built by this core commitment allowed GS5 expand into additional areas of excellence: open source intelligence (OSINT) analysis, modeling and simulation, testing and evaluation, cyber, and beyond.

After over a decade of growth, GS5 possesses qualified personnel, appropriate facilities, and an unblemished track record of accomplishing its mission.

Today, GS5 provides recognized and dependable support to the Federal and commercial markets, especially in the Intelligence Community. Through contracts with DOD, DHS, the IC, and commercial clients, GS5 has built a reputation for delivering cost-effective products, timely insight, and actionable solutions—all with a persistent focus on the needs of the client, and ultimately on the betterment of our nation.
