More on the SIA largest staffing firms list

SIA’s list of the largest staffing firms includes staffing-related revenue, which it defines as revenue generated from the provision of temporary workers to business clients; “place and search” services (direct hire/permanent placement and retained search); and “temp-to-hire” conversions.

According to SIA, the 251 firms on the 2023 list generated $168.8 billion, which accounts for 77.2 percent of the market.

“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 U.S., the companies listed account for over three quarters of U.S. 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.”
