# Six3 Systems: High-Level Overview
Six3 Systems is a national security and defense intelligence services provider that develops and acquires specialized capabilities for the U.S. Intelligence Community, Department of Defense, and civilian security agencies.[1] Founded in July 2009 by industry veteran Bob Coleman in partnership with GTCR, the company operates around six core values—Integrity, Ethics, Partnership, Trust, Quality, and Innovation—to serve three key markets: Defense, Intelligence, and Civilian communities.[1][2]
The company delivers mission-critical solutions across biometrics, identity intelligence, counterintelligence, command and control systems, intelligence surveillance and reconnaissance (C5ISR), and cybersecurity.[2] Six3's business model centers on identifying and acquiring specialized capabilities through strategic acquisitions, then integrating them into a cohesive portfolio that addresses complex national security challenges. The company operates as part of a larger family of industry-leading subsidiaries, including Six3 Advanced Systems (formerly BIT Systems) and Six3 Enterprise Systems (formerly Novii Design).[2]
# Origin Story
Six3 Systems was established in July 2009 by Bob Coleman, an industry veteran with deep expertise in national security and defense sectors, in partnership with GTCR, a Chicago-based private equity firm specializing in transformational acquisitions.[1] The company's founding strategy centered on identifying management leaders in core defense and intelligence domains, then acquiring and building market-leading companies through organic growth and strategic M&A activity.
The company's early growth was marked by a series of four acquisitions that established strong positions in intelligence surveillance and reconnaissance, intelligence operations, and cybersecurity.[1] This acquisition-driven approach culminated in November 2013 when GTCR completed the sale of Six3 Systems to CACI International for $820 million, integrating Six3 into a larger provider of information solutions and services to government customers.[1]
# Core Differentiators
# Role in the Broader Tech Landscape
Six3 operates within the defense and national security technology sector, which has experienced sustained demand driven by evolving cyber threats, intelligence modernization initiatives, and the need for advanced biometric and identity management systems. The company's focus on specialized, high-value capabilities reflects a broader trend in defense contracting toward acquiring niche expertise rather than building everything in-house.
As a subsidiary of CACI International since 2013, Six3 benefits from integration into a larger ecosystem of government technology solutions while maintaining its specialized focus. The timing of Six3's growth—particularly its expansion during the 2009-2013 period—coincided with increased U.S. government investment in intelligence capabilities, cybersecurity, and counterintelligence operations following the post-9/11 security environment.
# Quick Take & Future Outlook
Six3 Systems exemplifies the successful acquisition-and-integration model in defense technology, where specialized expertise and strong management teams command premium valuations. The company's $820 million acquisition price reflected the value of its accumulated capabilities and customer relationships within the intelligence community.
Looking forward, Six3's trajectory will likely be shaped by continued government investment in cybersecurity, biometric technologies, and advanced intelligence analytics. As part of CACI International, the company is positioned to leverage broader corporate resources while maintaining its focus on high-value, specialized mission solutions. The convergence of artificial intelligence, advanced data analytics, and evolving national security threats suggests sustained demand for the types of specialized capabilities Six3 provides to U.S. government agencies.
