This year, Staffing Industry Analysts counted 251 staffing firms with $100 million or more in US revenue, up from 225 last year, according to the “Largest Staffing Firms in the United States: 2023 Update” report, released on Monday. Healthcare staffing firms represented 30% of the firms on the list while IT staffing providers represented 28% and industrial firms represented 25%.
“With 251 companies in this year’s report of staffing firms over $100 million in US revenue, this market share analysis provides by far the largest and most comprehensive listing that we have ever produced highlighting the diverse landscape of US staffing. While the industry overall is quite fragmented, with more than 20,000 staffing firms in the US, the companies listed account for over three quarters of US staffing market revenue,” said Barry Asin, SIA President. “Additionally, this report highlights the growth of the industry, as the number of firms over $100 million has grown from just 98 in 2010 to 225 in 2021 and now to more than 250 last year.”
Allegis Group, based in Hanover, Maryland, ranked as the largest US staffing firm. It was followed by Aya Healthcare, a San Diego-based healthcare staffing firm.
