About the company
Greystones Consulting Group, LLC, a SBA-certified women-owned small business based in Washington, D.C., operates as a prime contractor on federal engineering, systems integration, and defense technology programs, with 89% of its recent awards held at the prime level and a portfolio combining full-and-open and set-aside delivery orders across Navy, Air Force, and defense agency customers. The firm competes predominantly in full-and-open competition rather than reserved set-aside vehicles, though its women-owned designation makes it competitive on small-business set-asides when applied.
Greystones' footprint is heavily concentrated in Department of the Navy work—22 awards totaling $10.07 billion in combined potential value represent 67% of its award count and essentially all of its dollar value. Within Navy, the Naval Sea Systems Command dominates, followed by smaller activity under the Chief of Naval Operations and the Office of Naval Research. The Air Force and Office of the Secretary of Defense round out the top-dollar customers: a $950 million Advanced Battle Management Systems support contract under the Air Force and a $249 million AI Talent 2.0 Basic Ordering Agreement with the Office of the Secretary of Defense. GSA Federal Acquisition Service places six smaller orders, primarily through the Multiple Award Schedule. The concentration is striking—the top two customers account for substantially all of the $11.31 billion in combined potential value.
Greystones holds four parent vehicles, three of them with Navy. The flagship vehicle is a $151 billion multiple-award Indefinite Delivery Indefinite Quantity contract awarded December 29, 2025, by the Missile Defense Agency titled Scalable Homeland Innovative Enterprise Layered Defense (SHIELD), covering research, development, systems engineering, production, test and evaluation, and cybersecurity across multi-domain defense with an ultimate completion date of December 28, 2035. The $249 million AI Talent 2.0 BOA with the Office of the Secretary of Defense (expiring May 5, 2028) provides technical support in software development, artificial intelligence, cloud services, and cybersecurity. Seaport Next Generation (Seaport-NXG), a Navy multiple-award IDIQ, anchors four task orders worth $50.9 million combined, with the most recent being a March 31, 2026, delivery order worth $28.5 million for professional and engineering support services to Naval Sea Systems Command running through March 30, 2031 on a cost-plus-fixed-fee basis. Greystones also holds ten task orders worth $15.7 million under the 8a Streamlined Technology Acquisition Resources for Services (8a STARS) contract.
The vendor's concrete capability framing centers on naval systems engineering, software sustainment, weapons-system integration, and defense technology modernization. Representative named work includes the $28.5 million Seaport-NXG delivery order for NAVSEA06D professional and engineering support; $1.77 million small-business set-aside delivery order from the Washington Headquarters Service to provide a programmatic financial expert to the Chief Digital and AI Officer's Enterprise Platforms & Services division (awarded September 27, 2024, with performance February 2026–February 2027); software and security patch sustainment for the JAG Enterprise System (JES) under the Multiple Award Schedule; and integration and engineering services for intercontinental ballistic missile weapon systems as a subcontractor to BAE Systems Technology Solutions & Services Inc. (three awards from November 2021 through January 2024). A subsidiary, Mission-Insights LLC, a joint-venture women-owned small business, performed cybersecurity work on identity-theft detection and reduction for the IRS under a Mission-Insights LLC prime award (September 29, 2025).
Activity trajectory shows growth in award count—one award in 2022 to four in 2025—but award counts alone mask dollar concentration: the SHIELD IDIQ and AI Talent 2.0 BOA awarded in late 2025–early 2026 represent the vast majority of recent potential value. Only one award with a combined potential value of $1.8 million faces ultimate completion inside the next twenty-four months, placing minimal recompete pressure on the vendor in the near term. Across its subcontractor footprint, Greystones subs to BAE Systems on ICBM integration and engineering, to Science Applications International Corporation on TSM helpdesk support for Naval Surface Warfare Center Corona, and to Mission-Insights LLC on cybersecurity work—a relatively light sub engagement that reflects Greystones' posture as a prime-focused firm.
GSA Schedule labor rates span $49.81/hr to $311.55/hr across twenty active categories, covering data analysts, task managers, program managers, and subject-matter experts with education from high school through master's degree and no security-clearance requirements listed. Service Contract Inventory data captures minimal activity ($0 invoiced in FY2024 as a prime, with roughly 2.2 FTEs on federal service contracts in FY2024), indicating that most Greystones work flows through larger IDIQs and delivery orders rather than through labor-hour service contracts above the SCI reporting threshold.
