About the company
By Light Professional IT Services LLC, a for-profit limited liability company headquartered in Tysons, Virginia, and a subsidiary of Sagewind Capital LLC, operates as a prime contractor on multiple government-wide and agency-specific indefinite-delivery vehicles delivering IT infrastructure, simulation and training systems, cybersecurity services, and systems engineering across defense and civilian federal agencies. The vendor competes predominantly full-and-open, without set-aside restrictions on most prime awards, though recent activity includes several Total Small Business set-aside delivery orders for flight training device procurement and simulator modernization work.
By Light's capability portfolio centers on concrete, mission-critical domains: flight training device procurement and sustainment (cockpit and cabin flight trainers, H-1 aircrew trainers, CH-53K advanced aviation training devices); tactical environment network software integration and modernization for Marine Corps training infrastructure; identity and access management (IAM) services for the Department of Veterans Affairs; IT infrastructure and network modernization; and specialized communications support including high-frequency radio equipment and satellite communications. Representative prime work includes a $209.9 million comprehensive modernization (COMPMOD) delivery order under the ENCORE III DoD IDIQ running through February 2031; a $138.5 million identity and access management delivery order with VA Technology Acquisition Center under T4NG running through July 2029; a $95.7 million flight training device software update order with Naval Air Warfare Center under the Training Systems Contract IV (TSC) running through February 2029; and a $70.3 million MyHealtheVet IT development, security, and operations delivery order with VA under T4NG running through July 2025. Additional recent work includes a $43.2 million delivery order from PEO Simulation, Training and Instrumentation for procurement of two cabin flight training devices in the United Kingdom and a $37.6 million delivery order from Security Assistance Command for procurement, installation, and certification testing of cockpit flight training devices, also in the United Kingdom, both under Total Small Business set-asides.
By Light holds positions on multi-billion-dollar government-wide vehicles: Alliant 3 (awarded February 2026, no dollar ceiling specified in the source, extending through March 2036); OASIS+ Unrestricted (awarded December 2024, no dollar ceiling specified in the source, extending through December 2029); the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ with the Missile Defense Agency (awarded December 2025, $151 billion ceiling, extending through December 2035); the DLA J6 Enterprise Technology Services 2.0 (JETS 2.0) IDIQ (awarded October 2024, $11.93 billion ceiling, extending through October 2034); and the Army Modernization Priorities Multiple Award Contract (AMP) IDIQ (awarded June 2023, $900 million ceiling, extending through May 2033). The vendor also holds agency-specific vehicles including the Transformation Twenty-One Total Technology Next Generation (T4NG) IDIQ with the Department of Veterans Affairs (multiple delivery orders; combined potential value $1.27 billion across 26 task orders), a single-award $40.8 million indefinite delivery contract with Naval Air Warfare Center for Marine Corps Tactical Environment Network upgrades, and the Accelerating VA Innovation and Learning (AVAIL) IDIQ with VA ($650 million ceiling, extending through September 2027). GSA vehicles include the Multiple Award Schedule (241 task orders, $125.4 million combined potential value) and Information Technology Schedule 70 (104 task orders, $26 million combined potential value). By Light also participates in Other Transaction Agreements: a $19.6 million H-1 Mission Rehearsal Trainer follow-on production OTA with Naval Air Warfare Center through Consortium Management Group, Inc., and a $2.7 million H-1 Aircrew Trainer OTA.
Customer concentration clusters heavily around the Department of Veterans Affairs Technology Acquisition Center Austin (101 awards, $24.26 billion combined potential value), which anchors 16% of all prime awards and 64% of the top-five customers' combined potential-value share. The Defense Information Systems Agency (58 awards, $1.51 billion) and the Department of the Navy Naval Air Warfare Center (14 awards, $1.17 billion) represent secondary concentrations. GSA Federal Acquisition Service (11 awards, $92.55 billion combined potential value) dominates the potential-value ranking, driven by By Light's GWAC and OASIS+ positions. The vendor serves 121 distinct federal agencies across 643 total awards. Activity has averaged 36–46 prime awards annually over 2022–2024, with a decline to 18 awards in 2025 and 5 awards year-to-date in 2026, partly reflecting the snapshot timing of the source. Seventeen awards with combined potential value $617.4 million face ultimate completion inside the next twenty-four months, creating recompete exposure.
By Light operates as a prime on 85% of recent awards (545 of 643) and as a subcontractor on 15% (98 awards). When delivering as a subcontractor, By Light supplies IT infrastructure, network engineering, simulation systems development, and communications support to larger defense primes including Leidos, Lockheed Martin, Science Applications International Corporation (SAIC), Competitive Range Solutions LLC, Full Spectrum Operations LLC, Booz Allen Hamilton, and General Dynamics. On SCI-reportable prime service contracts, By Light averaged 18% sub-hours share, indicating moderate reliance on teaming partners; 104 named subcontractors appear across the prime contract portfolio. The vendor invoiced $297.9 million across SCI-reportable prime service contracts from FY2022 to FY2024 ($143.7 million in FY2022, $84.1 million in FY2023, $70.1 million in FY2024), reflecting declining SCI-captured activity. FTE counts fluctuated from 575 in FY2022 to 186 in FY2023 to 402 in FY2024, driven by the mix of contract vehicles and task-order volumes. On federal services contracts captured in SCI, median government-paid rates ran around $147.77/hr, with the 90th percentile reaching $367.42/hr, consistent with specialized technical and engineering roles. GSA Schedule labor offerings span 183 categories at hourly rates from $43.72 to $213.57, covering roles from helpdesk specialists through senior communications engineers with bachelor's and master's-level education; no security-cleared positions are published on the schedule.
By Light's corporate structure comprises nine subsidiaries under parent Sagewind Capital LLC: Cole Engineering Services, Inc. (manufacturer of goods for simulation and training systems), Dignitas Technologies LLC, Axom Technologies LLC, Halo Aeronautics LLC (self-certified HUBZone joint venture), Orqa US LLC, Raydon Corporation, Dignitas Technologies JV LLC, and Opsidian LLC (women-owned small business joint venture and self-certified HUBZone joint venture). The subsidiary portfolio suggests capability breadth across aerospace training systems, specialized engineering, and set-aside positioning for HUBZone and WOSB opportunities, though recent prime awards reflect By Light's primary full-and-open competitive posture at the parent company level.
