SI3 competitors and assessment
Company assessmentRegional players
- Kforce: U.S.-based technology staffing and solutions firm placing consultants into federal, financial, and commercial engagements. Comparable to SI3 for its fractional/consultative technology staffing model and federal exposure, though Kforce operates at substantially greater scale and breadth.
Direct peers
- Slalom: Management and technology consulting firm delivering strategy, process engineering, AI integration, and digital transformation to commercial and public-sector clients. Comparable to SI3 on the Fractional CTO, process engineering, and AI integration service lines, particularly for the private-sector segment of SI3's book.
- Agile Defense: Federal IT services and cybersecurity firm serving DoD and federal civilian agencies with software development, AI, and digital modernization. Comparable to SI3 as a small, focused federal IT services competitor competing for similar set-aside and small-business work.
- IntelliBridge Partners: Small-to-mid federal IT services firm delivering digital transformation, AI/ML, and data analytics to defense and intelligence customers. Most directly comparable peer to SI3 by scale and federal focus, with similar customer profile (DoD/intel) and overlapping AI/integration capabilities.
Broad incumbents
- ManTech International: Federal technology solutions contractor specializing in intelligence, defense, and federal civilian work, particularly signals intelligence and cybersecurity. Strong overlap with SI3's intelligence and threat detection offerings; comparable at the capability level but with materially greater scale.
- CACI International: Federal IT services and intelligence provider delivering signals intelligence, cyber, and enterprise IT solutions to DoD and intelligence customers. Closely comparable to SI3 on signals intelligence, threat detection, and edge networking work, but operates at prime-contractor scale.
- SAIC: Federal IT and engineering services provider serving defense, intelligence, and civilian agencies with systems integration, AI/ML, and digital modernization. Overlaps with SI3's federal IT and engineering practice and shares the same buyer set; meaningfully larger and publicly traded.
- Booz Allen Hamilton: Largest U.S. federal management and technology consulting firm, providing systems engineering, AI, cybersecurity, and program management to DHS, DoD, and the intelligence community. Comparable to SI3 because it serves the same federal buyers with overlapping capabilities (program management, systems integration, AI/data analytics), but operates at vastly greater scale across a much broader portfolio.
- Leidos: Major federal systems integrator delivering IT, engineering, and mission solutions to DoD, intelligence community, DHS, and civil agencies. Directly comparable to SI3's federal systems engineering, AI integration, and signals intelligence footprint, but with a global delivery model and tens of thousands of employees.
Others
- Kinetic IT Systems: Bryant Haines' prior company, where he served as CEO for thirteen years before founding SI3. Cited because Bryant's most relevant operational track record and federal network were built there, providing a useful benchmark for SI3's growth trajectory and founder capability.
