Sigma Defense

About

In 2006, Scott Ritchie co-founded Sigma Defense with a vision to bridge the gap between traditional defense contracting and modern technological innovation. The company was born from a simple observation: the Department of Defense needed agile, software-first solutions that could keep pace with rapidly evolving threats, but existing vendors were mired in legacy approaches. Starting with a focus on tactical communications, Sigma Defense evolved by integrating hardware, software, and AI-driven intelligence to deliver mission-ready outcomes for U.S. and coalition forces.

Today, Sigma Defense has grown into a $500MM enterprise through strategic acquisitions and organic growth, including the additions of SOLUTE, SUB-U Systems, Electronic Warfare Associates, and Aries Defense. Under CEO Matt Jones' leadership, the company delivers integrated solutions across CJADC2, C5ISR, electronic warfare, and DevSecOps. Their flagship Olympus ecosystem provides the first technology ecosystem dedicated to enabling Combined Joint All-Domain Command and Control, serving as the U.S. Navy's de facto DevSecOps platform. With nearly half their team having served in uniform, Sigma Defense combines battlefield insight with cutting-edge technology to serve all U.S. military branches from tactical edge to command center.
