About the company
Tiax LLC, a Lexington, Massachusetts-based technology development company, operates as a prime contractor (100% of recent awards) supplying advanced materials, specialized protective equipment, and research and development services to the Department of Defense and civilian federal agencies under full-and-open and small-business set-aside designations. Tiax is structured as a for-profit limited liability company with no reported SBA certifications; recent awards carry both full-and-open and Total Small Business set-asides, with the latter appearing on discrete purchase orders and SBIR Phase I awards rather than across a systematic set-aside posture.
Tiax's capability portfolio centers on two distinct domains. The first is advanced materials and specialized protective equipment for military aviation and personnel: life preserver vests, body inflation devices, bladder assemblies, protective dust caps, fasteners, and components for the Integrated Aircrew Ensemble (IAE) program, including chemical, biological, and radiological protective layers and survival vest components. The second is research and development in materials science and engineering, particularly for cold-weather protection systems, power systems components, and aerospace applications. Representative work includes a $6.19 million Integrated Aircrew Ensemble delivery order with the Air Force Materiel Command Aeronautical Systems Center (awarded November 2023, completing April 2025), a $364 thousand life preserver vest procurement from DLA Troop Support (June 2025), a $156 thousand IAE zipper replacement qualification delivery order with the Air Force (March 2024), and a $74,929 SBIR Phase I award from the Air Force Research Laboratory for active cold weather protection (May 2024).
Customer concentration is dominated by the Air Force. The Department of the Air Force Materiel Command Aeronautical Systems Center accounts for 15 awards worth $170.1 million of combined potential value — 67% of the top-five customers' aggregate value and roughly 33% of Tiax's total portfolio by dollars. The Department of Energy (26 awards), the Department of the Army Materiel Command Research Development and Engineering Center (20 awards, $7.2 million), the Department of Transportation (12 awards, $9.5 million), and the Air Force Research Laboratory (12 awards, $2.6 million) round out the active set. This concentration is visible in both award count and dollar magnitude — the Air Force's ranking is stable across both metrics.
Tiax places task orders under two primary vehicles: an Air Force Indefinite Delivery Contract (FA860611D6360) carrying 16 task orders worth $96.5 million in combined potential value, and the General Services Administration Professional Services Schedule with 19 task orders worth $5 million. These vehicles anchor the majority of Tiax's delivery work; the IDIQ alone represents roughly 38% of the total portfolio value.
Activity has accelerated recently. Tiax recorded one award per year in 2022 and 2023, then expanded to six awards in 2024 and eight in 2025, with two awards already in 2026. However, the recompete cliff is minimal — only one award carrying $68 thousand is scheduled to complete in the next twenty-four months, indicating low near-term renewal exposure. Across all 248 awards, Tiax has obligated $194.1 million against a combined potential value of $253.9 million, representing 76% obligation rate. The vendor operates exclusively as a prime (zero sub-awards), performing work across 56 distinct customer agencies with concentrations in R&D-classified work (98 awards in physical, engineering, and life sciences R&D; 21 awards in basic research) and specialized flight clothing and accessories (13 awards).
