Great Hill Solutions, LLC

Great Hill Solutions, LLC, a tribally-owned SBA Certified 8(a) Program Participant headquartered in Chantilly, Virginia, operates as a prime contractor delivering subject matter expert personnel, program management, administrative staffing, healthcare IT modernization, and test-and-evaluation support services to the Department of Defense, Department of State, and civilian agencies, with 99% of its recent award footprint as prime and roughly $595.3 million obligated across a $1.49 billion combined potential-value portfolio.

Great Hill Solutions is a portfolio company of Seneca Holdings, LLC, the investment arm of the Seneca Nation of Indians, and holds SBA 8(a) certification through July 10, 2030. The vendor competes predominantly under 8(a) sole-source and competitive 8(a) set-asides, though recent awards also include full-and-open delivery orders and definitive contracts. Native American and tribally-owned designations are core to corporate identity; the vendor carries minority-owned-business and American Indian-owned certifications across its subsidiary portfolio.

Customer concentration is substantial and defense-heavy. The top five funding agencies account for 72% of combined potential value: the Department of Army's Program Executive Office for Simulation, Training and Instrumentation anchors the portfolio with 13 awards valued at $275.3 million; the Department of State's Bureau of South and Central Asian Affairs (primarily the Care Contact Center delivery order) carries $248.3 million across three awards; the Defense Health Agency holds 11 awards worth $219.5 million; the Naval Air Warfare Center brings $190.1 million across two awards; and US Special Operations Command accounts for $145.1 million across seven awards. The Office of the Secretary of Defense places 13 orders worth $13.9 million, primarily through Agile Reaction Test (ART) programs. Concentration reflects the vendor's specialized expertise in program management, subject matter expert staffing, and defense test-and-evaluation infrastructure.

Activity has grown sharply: seven awards in 2022, 17 in 2023, 29 in 2024, 29 in 2025, and eight in 2026 (year-to-date through September). SCI-reportable federal service-contract invoicing increased from $8.1 million in FY2022 (45.6 FTEs) to $158 million in FY2025 (452 FTEs), representing compound year-over-year growth in the federal services footprint. However, 22 awards (combined potential value $503.2 million) reach ultimate completion within the next twenty-four months, creating significant recompete exposure—notably the Care Contact Center contract ($244.5 million ceiling, ultimate completion December 14, 2026), the Defense Health Agency's Military Health System Genesis contract ($80.97 million, March 17, 2029), and multiple PEO Simulation, Training and Instrumentation delivery orders.

Great Hill Solutions anchors its federal presence on five multi-year IDIQs and three GSA vehicles. The TIPS (Test and Instrumentation Professional Services) IDIQ with PEO Simulation, Training and Instrumentation is a $150 million single-award contract extending through March 29, 2030, against which the vendor has obligated approximately $132.7 million in delivery orders for subject matter expert personnel supporting test resource management and cyber warfare domains. The US Special Operations Command IDIQ carries a $100 million ceiling through December 31, 2028, funding C4IAS, SOCRATES, Chinook sustainment, and Android development task orders. The Naval Air Warfare Center NLIFTE contract is valued at $98.9 million through August 1, 2028, supporting naval modeling and simulation infrastructure. The State Department's Bureau of Administration staffing IDIQ runs through October 21, 2026, at $15 million, generating multiple task orders across Near Eastern Affairs, South and Central Asian Affairs, and European bureaus. The Missile Defense Agency's newly awarded SHIELD IDIQ carries a multi-billion-dollar ceiling through December 28, 2035, supporting advanced multi-domain defense research, prototyping, and systems engineering. Across GSA vehicles, Great Hill Solutions holds competitive 8(a) seats on OASIS+ 8(a) and OASIS+ Total Small Business (both multiple-award, no ceiling limit, through 2029), OASIS+ Unrestricted (multiple-award, through December 16, 2029), and a Federal Supply Schedule contract (92 labor categories spanning $35.99 to $250.04 per hour, no security-cleared roles, through October 21, 2029). The TIPS, USSOCOM, and Naval Air Warfare Center vehicles generated 19, 12, and 12 task orders respectively in recent activity.

Concrete capability work reflects the vendor's deep bench in defense subject-matter expertise and administrative scale. Representative contracts include a $244.5 million labor-hours Care Contact Center delivery order with the State Department's Bureau of South and Central Asian Affairs (awarded December 15, 2021, ultimate completion December 14, 2026, invoiced $144.1 million through FY2025 with 160–183 FTEs annually at $113.88–$167.45 per hour); an $80.97 million Defense Health Agency contract for Military Health System Genesis issue resolution and roles management support (awarded September 18, 2023, ultimate completion March 17, 2029, invoiced $30.3 million through FY2025 at $156.66 per hour); a $36.475 million delivery order for Test Resource Management Center subject matter expertise with PEO Simulation, Training and Instrumentation (February 7, 2026, Cost No Fee, ultimate completion February 6, 2031); a $52.2 million CDC delivery order for programmatic and scientific labor support to the Coronavirus and Other Respiratory Viruses Division under OASIS+ Total Small Business (January 5, 2026, competitive 8(a), firm fixed price, ultimate completion January 4, 2031); and a $38.5 million Defense Health Agency Revenue Cycle Modernization delivery order under OASIS+ 8(a) (September 30, 2025, competitive 8(a), ultimate completion September 29, 2030). Smaller orders include a $19.5 million USSOCOM commercial cloud architecture and engineering support delivery order (September 11, 2026, 8(a) sole source, ultimate completion September 12, 2031), a $15.2 million PEO Simulation acquisition support and cyber warfare expertise task order (July 18, 2025, Cost No Fee), and multiple Office of the Secretary of Defense Agile Reaction Test (ART) orders (EVADE, J-CONDOR, J-DART, GAIMI, J-GHOST II) ranging from $619 thousand to $1.4 million each, all 8(a) sole source, firm fixed price, through 2026.

On SCI-reportable federal service contracts, Great Hill Solutions operates as a predominantly self-performing prime. Across 67 prime SCI records, subcontractors perform an average of 12% of contractor hours, with 40 named subcontractors engaged across the portfolio. Government-paid median rates run approximately $105.25 per hour, with a 10th percentile of $70.17 per hour and 90th percentile of $258.59 per hour—the wide spread reflecting mix of administrative labor (lower-cost roles in data entry, support, and compliance) and subject-matter expert positions (higher-cost engineering, program management, and specialized technical roles). On the GSA Schedule, the vendor offers 176 labor categories spanning entry-level roles (Data Entry Specialist, $35.99/hr) through senior positions (Program Manager–Principal, $250.04/hr), with education requirements from high school to bachelor's degree and no security-cleared roles; this breadth supports rapid micro-purchase and BPA ordering across federal agencies. The vendor does not report classified-contract work or security-clearance-required positions in the SCI dataset.

Subcontractor engagement is light. The vendor appears in one visible sub-award role: a $1 million Executive Assistant and Program Management Support sub-task to TSI Federal LLC (November 17, 2023). The primary teaming model is self-delivery with occasional sub-engagement for specialized labor fills (12% of hours across the portfolio), rather than reliance on prime-tier subcontractors. Named sub-engagement includes Zygos Consulting LLC for contracting and program management advisory on a Defense Security Cooperation Agency program management contract (contract value $22.2 million, FY2024 invoicing $2.2 million).

Category concentration reflects the vendor's core competencies. Top NAICS codes include Administrative Management and General Management Consulting Services (27 awards), Custom Computer Programming Services (20 awards), Engineering Services (13 awards), and Other Computer-Related Services (8 awards). Top PSC codes span IT and Telecom Security and Compliance as a Service (20 awards), Support–Professional Program Management (17 awards), Support–Professional Engineering and Technical (15 awards), and Support–Professional Other (10 awards). The portfolio skews toward test-and-evaluation infrastructure support, healthcare IT modernization, personnel security and administrative staffing, and command-and-control systems engineering—all with deep defense customer concentration.
