About the company
Zkxkz LLC, a Massachusetts-based small business operating exclusively as a prime contractor on Small Business Innovation Research (SBIR) awards, delivers advanced materials science, imaging systems, and sensing technology research and development to defense and transportation agencies under total small business set-asides. The firm has no subcontract footprint and competes entirely within the SBIR program across Department of Defense components and the Department of Transportation.
Zkxkz is a for-profit limited liability company headquartered in Lexington, Massachusetts, with primary NAICS alignment to research and development in physical, engineering, and life sciences (17 of 26 awards in the source window). The company's capability portfolio centers on x-ray-based automated testing systems, advanced materials for active protection and armor applications, wireless wearable sensors, artificial intelligence for visual processing of defects, and modular construction techniques for transportation infrastructure. Recent representative work includes a $1.3 million Direct to Phase II SBIR award from the Defense Health Agency for development of a wireless, wearable personal metabolic sensor (ultimate completion August 4, 2027); a $1.25 million firm fixed-price purchase order from the Air Force Research Laboratory for a high-energy upgrade to a quantitative x-ray system for Arena tests (completion September 21, 2026); a $750 thousand Phase II SBIR effort from the Air Force Research Laboratory for advanced hardware and software for x-ray-based automated arena test data collection (completion August 21, 2026); and a $224,885 Phase I SBIR award from the Shared Services Center for active protection from micrometeoroids, announced September 30, 2026.
Customer concentration sits heavily with the Air Force Research Laboratory, which accounts for 8 of 22 named awards and $6.7 million of the $14.6 million combined potential value. The Army Materiel Command Research Development and Engineering Command, the Department of Transportation, and the Naval Sea Systems Command each contribute four awards. The top five customers by potential value cover 93% of combined potential value, with the Air Force, Army, DOT, Defense Health Agency, and Navy accounting for the majority. Awards per year have declined from three in 2022 to one in 2026, though the source window captures only partial 2026 activity (most recent award September 30, 2026). Two awards carrying combined potential value of $1.5 million face ultimate completion within the next twenty-four months and represent recompete exposure. Zkxkz operates with no parent IDIQs, GWACs, or agency-wide contract vehicles; all awards are direct SBIR definitive contracts or purchase orders, meaning the vendor must compete in each SBIR cycle rather than place task orders under standing vehicles.
