Released this year on July 10, SIA examined reports from estimated 2023 staffing revenue and market share, as well as largest skill segments supplied and headquarter locations for each firm to compile the rankings.

ZRG was listed among 241 of the largest staffing firms in the nation that generated revenue of at least $100 million in 2023. In total, the firms in this list generated $145.2 billion in revenue, thereby comprising 76.0% of the domestic market by SIA estimates.

“We are honored to be recognized among the top players in the industry,” said Larry Hartmann, CEO of ZRG, one of the fastest growing talent firms in the world. “We have been able to climb these rankings through expansion beyond executive search to offering “culture fit,” interim, and RPO services and through strategic acquisitions over the past few years.”

Recent domestic acquisitions by ZRG include Brimstone Consulting Group, a boutique strategy consulting firm (Dec. 2021); RoseRyan, Inc., a Silicon Valley-based provider of finance and accounting consulting solutions (April 2022); Helbling & Associates, a national executive search firm focused on real estate, facilities, and construction (June 2023); and The Registry, an Interim Executive Solutions firm specializing in higher education (August 2023).

ZRG also recently acquired London-based executive search firm Walter James (Dec. 2021); Walking The Talk, a leading culture consulting firm (July 2021); and Ignata Finance Group (March 2024). ZRG’s organic growth continues across the UK, EU, and Middle East in retained search, on-demand talent solutions, and consulting.
