As we enter 2025, Federal IT & Consulting services firms face unprecedented competition in a rapidly evolving marketplace. A new administration brings fresh priorities, and the pace of technology innovation is accelerating. Change is not just expected; it’s guaranteed. In this environment, the 2025 OrangeSlices Vanguard FedCiv 250 spotlights the most successful firms with a proven track record of securing federal services contracts in FY 2024 across the Federal Civilian Sector and excelling in the fiercely competitive federal market.
This prestigious list was crafted in partnership with HigherGov, the groundbreaking market intelligence and business development provider that has become an indispensable asset to the Federal Government contracting (GovCon) community since its launch in 2022. More than a thousand contractors, agencies, and advisors turn to HigherGov for the latest insights and competitive edge, solidifying its role as a go-to authority for navigating the complexities of the Federal marketplace.
The selected firms listed below stand out as leaders in Federal Civilian IT & Consulting services by obligated funds (including both prime and reported subcontractor dollars) across a targeted set of NAICS and PSC codes for Fiscal Year 2024. While past success doesn’t guarantee future wins, these companies’ track records of identifying, competing for, and securing contracts make them essential partners to get to know for any industry or government leader to aiming to drive forward in this demanding sector.
