Addison Group
CHICAGO (July 1, 2025) — ADDISON GROUP, a national leader in talent solutions and consulting services, is proud to announce its ninth consecutive year of recognition as one of the largest staffing firms in the United States. This recognition, awarded annually by Staffing Industry Analysts (SIA), reflects Addison Group’s consistent performance, continued expansion, and unwavering commitment to people-first values in a quickly developing employment landscape.
In the 2025 SIA listing, 224 companies achieved revenue of at least $100 million in 2024. Collectively, these listed firms generated $126.4 billion, representing a substantial 68% market share. SIA’s rankings comprehensively assess the market landscape, comparing the largest providers across different countries, regions, and categories.
Addison Group continues its consistent progress in multiple categories:
“We’re incredibly proud to be named one of the largest staffing firms in the U.S. for the ninth year in a row. It’s a reflection of the amazing people we have at Addison Group, the strong relationships we’ve built with our clients, and the top talent we’ve worked hard to attract and retain. Putting people first has always been at the heart of what we do, and it’s what drives our continued success.”
Thomas Moran, CEO, Addison Group
Amid ongoing economic fluctuations and transformation within the staffing industry, Addison Group has maintained its position through the strategic acquisition of high-performing niche companies. These acquisitions have expanded its service offerings, strengthened its national presence, and reinforced its People-First philosophy.
According to the SIA Editorial Staff, “Fewer companies made SIA’s Largest Staffing Firms in the US list this year as the industry continues through a slow period.” The article highlighted that “The new report, released June 10, counted 224 staffing firms with $100 million or more in US staffing revenue. That’s down 7% from 241 last year. In addition, of the firms that qualified for both this year’s list and last year’s list, 75% experienced a decline in revenue.”
