About Knexus Research LLC
Knexus Research LLC Maryland Office Division, an SBA 8(a)-certified small business, delivers artificial intelligence, machine learning, data science, and research and development services to federal defense and civilian agencies as a prime contractor (98% of recent awards) across 14 distinct customer agencies. Based in Vienna, Virginia, with operations in Forest Heights and Oxon Hill, Maryland, the company is structured as a limited liability partnership specializing in advanced computational research, intelligent systems development, and technology innovation. Knexus competes predominantly full-and-open rather than set-aside, despite its 8(a) certification — only 3 of its 56 prime awards carry small-business set-aside designations; most sit on unrestricted vehicles.
Knexus's prime footprint spans research contracts, SBIR Phase I and Phase II efforts, single-award IDIQs, and blanket purchase agreements. Recent representative work includes a $1.438 million delivery order from Defense Logistics Agency Troop Support (April 2026) for Generative AI Logistics for Communication and Execution (GAILFORCE) production, scaling, and enterprise integration under a $50 million single-award IDIQ; a $1.191 million DARPA definitive contract (April 2026) for Public Usage Language Lab (PULL) Challenges research extending through April 2029 under cost-plus-fixed-fee pricing; a $1.097 million Naval Air Warfare Center SBIR Phase II contract (June 2025) for R&D services in Forest Heights with completion scheduled for January 2029; and a $4.697 million Census Bureau 8(a) sole-source disclosure avoidance research contract (awarded September 2021, completed March 2024). Knexus also holds a $877,453.50 delivery order from the National Institute of Standards and Technology (July 2026) for privacy-enhancing technologies testbed research under the GSA Multiple Award Schedule, and a $250,000 Other Transaction Agreement with PEO Simulation, Training and Instrumentation (April 2026) for a Product Support Forecasting Tool.
Customer concentration is heavily weighted toward Navy and DLA. The top five funding agencies by potential value represent 100% of combined potential value, led by Naval Sea Systems Command (2 awards, $4 billion potential value anchored by a $4 billion SeaPort-NXG IDIQ awarded January 2025), Defense Logistics Agency Troop Support (10 awards, $110.1 million), GSA Federal Acquisition Service (2 awards, $100.5 million), Office of Naval Research (25 awards, $27.2 million), and Census Bureau (3 awards, $13.2 million). By award count, the Office of Naval Research dominates at 25 awards but carries only $27.2 million in potential value, signaling a pattern of smaller-dollar R&D orders. DLA Troop Support places fewer awards (10) but anchors $110.1 million in potential value, including seven task orders under IDIQ SP470124D1020 worth $8.6 million combined. The gap between award count and dollar ranking reflects Knexus's role as a preferred vendor for Navy-sponsored research contracts alongside periodic large-value DLA logistics and GSA supply-chain vehicles.
Knexus holds significant vehicle positions across defense and civilian enterprise contracts. The company maintains a $50 million single-award IDIQ with DLA Troop Support for Generative AI Logistics (awarded April 2026, running through April 2031), a $4 billion SeaPort-NXG multiple-award IDIQ with Naval Sea Systems Command (awarded January 2025, running through January 2029), a $151 billion Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ with the Missile Defense Agency (awarded December 2025, running through December 2035), a $100 million Supply Chain Risk Illumination Professional Tools and Services (SCRIPTS) multiple-award BPA with GSA Federal Acquisition Service (awarded March 2025, running through March 2030), and a GSA Federal Supply Schedule contract with a $475,000 ceiling (awarded September 2021, expiring September 2026) offering labor categories spanning AI/ML software engineers, data modelers, and software architects at fully burdened rates from $98 to $201 per hour. The company places task orders primarily under its own IDIQ vehicles and the SeaPort-NXG and SCRIPTS vehicles held by others.
Activity has accelerated sharply. The company recorded 2 awards in 2022, 1 in 2023, 5 in 2024, and 13 in 2025; 6 additional awards have landed in 2026 year-to-date. Combined potential value across all 57 awards reaches $4.26 billion, though only $44.5 million (1%) has been obligated to date — the vast majority sits in ceiling value on large IDIQs and the SHIELD contract rather than funded task orders. Ten awards carrying combined potential value of $11 million reach ultimate completion within the next twenty-four months, creating modest recompete exposure; the SeaPort-NXG ($4 billion) and SHIELD ($151 billion) IDIQs run much longer and anchor the future pipeline.
The company operates as a prime across nearly all work (98 of 57 awards) with minimal subcontract footprint — one named sub-award surfaces: HII Mission Technologies Corp as prime on a Joint Network of Engineering and Emerging Operations (JNEEO) artificial intelligence software subscription task order (March 2026). NAICS and PSC concentration confirms Knexus's research-and-development posture: 28 awards fall under "Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology)," 15 under "Research and Development in the Physical, Engineering, and Life Sciences (except Biotechnology)," and 6 under "Computer Systems Design Services," with top PSC codes split between "National Defense R&D Services; Defense-Related Activities; Experimental Development" (10 awards) and "R&D — Defense Other; Applied Research/Exploratory Development" (7 awards). The corporate structure includes a named subsidiary, S4, LLC, a for-profit limited liability company, though the source does not detail its role or capability framing.
