Great Hill Solutions, LLC

Great Hill Solutions, LLC, a tribally-owned SBA Certified 8(a) Program Participant, operates as a prime contractor (99% of recent awards) delivering professional services spanning test and evaluation, healthcare IT modernization, administrative staffing, program management, and technical consulting across defense, civilian, and diplomatic agencies. Headquartered in Chantilly, Virginia, and operating as a portfolio company of Seneca Holdings (the investment arm of the Seneca Nation of Indians), Great Hill Solutions is an American Indian-owned small disadvantaged business with SBA 8(a) certification expiring July 10, 2030. The vendor competes predominantly under 8(a) set-asides—roughly 70% of recent awards carry sole-source or competitive 8(a) designations—and maintains a cumulative prime contract portfolio exceeding $500 million.

Great Hill Solutions' customer concentration is defense-heavy, anchored by the Department of Army's Program Executive Office for Simulation, Training and Instrumentation (13 awards, $271.1 million combined potential value) and the Defense Health Agency (10 awards, $205.9 million potential value). The Department of State's Bureau of South and Central Asian Affairs (3 awards, $248.3 million potential value) reflects a separate staffing-and-operations footprint, driven by a single large care contact center contract. The Naval Air Warfare Center ($190.1 million across two awards) and U.S. Special Operations Command ($124.3 million across six awards) round out the top five customer agencies by dollar value. These five customers account for 72% of combined potential value across all awards. Award volume has grown year-over-year—seven awards in 2022 to 29 each in 2024 and 2025—but 33 awards (combined potential value $539.3 million) reach ultimate completion within the next twenty-four months, creating significant recompete exposure.

Great Hill Solutions holds substantial IDIQ positions anchoring its federal presence. The vendor received a $150 million single-award IDIQ from the Missile Defense Agency (Scalable Homeland Innovative Enterprise Layered Defense / SHIELD) on December 29, 2025, with an ultimate completion date of December 28, 2035, covering multi-domain defense systems development, prototyping, test and evaluation, and modernization across air, missile, space, cyber, and hybrid threats. More operationally active is a $150 million single-award IDIQ with the Program Executive Office for Simulation, Training and Instrumentation (Test and Instrumentation Professional Services / TIPS) extending through March 29, 2030; Great Hill Solutions has exercised approximately $132.7 million in delivery orders against this vehicle for subject matter expert personnel supporting test resource management and cyber warfare domain expertise. The vendor also holds a $100 million single-award IDIQ with U.S. Special Operations Command (extending through December 31, 2028) and a $98.9 million single-award IDIQ with the Naval Air Warfare Center (extending through August 1, 2028), supporting operations and sustainment across special operations and naval aviation modernization initiatives. Additionally, Great Hill Solutions sits on three General Services Administration OASIS+ Multiple Agency Contracts (OASIS+ Unrestricted, OASIS+ Total Small Business, and OASIS+ 8(a)), each carrying a $999.999 trillion ceiling through late 2029. The vendor also holds a GSA Federal Supply Schedule contract (100 dollar catalog ceiling, October 2024 through October 2029) offering information technology and professional services across 92 labor categories with hourly rates spanning $35.99 to $250.04 and education requirements from high school through bachelor's degree; no security-cleared positions are offered.

Representative recent work demonstrates breadth across test-and-evaluation, healthcare modernization, and diplomatic operations. The Program Executive Office for Simulation, Training and Instrumentation issued a $36.475 million delivery order (February 7, 2026, ultimate completion February 6, 2031, Cost No Fee) for subject matter expertise supporting the Test Resource Management Center Central Test and Evaluation Investment Program. The Defense Health Agency awarded a $38.5 million competitive 8(a) delivery order (September 30, 2025, ultimate completion September 29, 2030, firm fixed price) for Revenue Cycle Modernization Innovation and Charge Description Master Support Services, performed in Falls Church, Virginia. The Centers for Disease Control and Prevention issued a $52.2 million competitive 8(a) delivery order (January 5, 2026, ultimate completion January 4, 2031, firm fixed price) for programmatic and scientific labor support to the Coronavirus and Other Respiratory Viruses Division at CDC's Atlanta facility. The Bureau of South and Central Asian Affairs contract—a $244.5 million definitive contract (December 15, 2021, ultimate completion December 14, 2026, labor-hours pricing)—for care contact center support generated $58.6 million in SCI-reported invoicing across 183 FTEs in fiscal 2024 alone, reflecting the vendor's largest single operational footprint.

Across SCI-reportable federal service contracts, Great Hill Solutions invoiced $175.8 million (prime records only) over fiscal 2022–2024, with year-over-year growth from $8.1 million (FY2022, 45.6 FTEs) to $40.6 million (FY2023, 173 FTEs) to $127.1 million (FY2024, 376 FTEs). The SCI dataset shows FTE trajectory from 23.6 in FY2022 to 785 across all records in FY2024, demonstrating rapid scaling. On federal services contracts captured in SCI, government-paid rates span a 10th percentile of $70.81 per hour through a 90th percentile of $250.85 per hour, with a median around $100.50 per hour. Across SCI-reportable prime contracts, Great Hill Solutions subcontracts an average of 17% of contractor hours, with 31 named subcontractors engaged; a single high-dollar contract (Military Health System Genesis issue resolution management at Defense Health Agency, $78.6 million ceiling, 8(a) sole source) reported one subcontractor performing 61% of contractor hours in FY2024, while most other contracts are self-performed or carry minimal sub-engagement.

Great Hill Solutions operates primarily as a prime contractor on its own delivery teams; the vendor's sub-contracting role is minimal (1% of recent awards). One reported subcontract, under TSI Federal LLC (November 17, 2023), was for executive assistant and program management support, indicating occasional use of larger primes for specialized niches. The vendor's dominant posture is prime-focused, leveraging its 8(a) status and tribal certification to anchor sole-source and competitive set-aside work while maintaining presence on unrestricted GWACs and GSA schedules to access full-and-open opportunities.

Capability concentration by PSC and NAICS reflects the vendor's service-centric profile: IT and Telecom Security and Compliance as a Service (19 awards), Support–Professional Program Management/Support (16 awards), and Support–Professional Engineering/Technical (15 awards) lead the PSC rankings. By NAICS, Administrative Management and General Management Consulting Services (27 awards), Custom Computer Programming Services (19 awards), and Engineering Services (13 awards) anchor the portfolio. This breadth—spanning test infrastructure, healthcare systems, diplomatic staffing, and IT modernization—reflects Great Hill Solutions' ability to deploy subject matter experts across multiple federal domains rather than specialization in a single functional area.
