SIA this year identified 66 firms with $100 million or more in IT staffing revenue, according to its Largest IT Staffing Firms in the United States: 2024 Update report. These largest firms posted revenue of $30.9 billion in 2023 and accounted for 80.7% of the market. 

“This year’s IT staffing list included 66 firms that generated more than $100 million in US IT staffing revenue, including eight with more than $1 billion in such revenue,” said Kevin Chen, SIA research analyst and author of the report. “Market share among the largest firms continued to fall, with the 15 largest firms accounting for 53% of the market, down from 58% in 2021. However, this trend may be reversed in 2024, as a couple of large IT staffing acquisitions have been already announced this year.”

The five largest firms are:

Four firms are included in this year’s ranking that did not appear in last year’s report: Prime Technical Services, Take2 Consulting, Talent Groups and Superbeo. 

Staffing firms varied in degree of financial transparency, and even when forthcoming with information, in some cases data provided was adjusted for greater accuracy and consistency. Therefore, revenue for all firms on this list should be considered an estimation by Staffing Industry Analysts.
