Allegis Group

Privately held talent-solutions group, largest US staffing firm per SIA

Overview

Allegis Group is a privately held talent-solutions company whose history, it says, began “in a basement in 1983 with two cousins”; it describes itself as a network of specialised companies with more than 500 locations worldwide.[13]

Because Allegis does not publish financial statements, the best available scale measure is the estimate compiled by Staffing Industry Analysts, which ranked Allegis Group first among US staffing firms in its June 2026 list, with US$9.11 billion of 2025 US staffing revenue.[12] That figure covers US staffing only and excludes its international and non-staffing operations. Its scale makes it a frequent candidate for large enterprise programmes; the lack of audited public disclosure means clients rely on the company’s own information for financial due diligence.
