Largest Staffing Firms Globally Achieve $190 Billion in Revenue

Mountain View, California — October 3, 2017 — Staffing Industry Analysts (SIA), the global advisor on staffing and workforce solutions, has released its 2017 report on the Largest Global Staffing Firms. The report features the top 100 staffing and recruitment firms worldwide ranked by their 2016 revenue.

“The firms comprising the 2017 list achieved a combined turnover of $190 billion,” said Barry Asin, President of SIA. “With the global staffing market generating revenues of approximately $428 billion in 2016, these firms represent an estimated 44% of total global revenue.”

The top five companies rank in the same order as they did in last year’s version of this report, with Adecco heading the ranking, followed by Randstad and ManpowerGroup again as second and third in the ranking. Allegis, the world’s largest privately-owned staffing firm, retained its fourth position, with Recruit as the fifth largest.

The five largest global staffing firms are:

Company 2016 Revenue ($ billions) Headquarters Country
The Adecco Group 22.5 Switzerland
Randstad 20.7 Netherlands
ManpowerGroup 19.2 United States
Allegis Group 10.2 United States
Recruit 9.8 Japan

Ten companies which did not appear in last year’s ranking were added to the 2017 list, including India-based Teamlease (81st) and Quess Corp (82nd); the Dutch firm Olympia Netherlands (92nd); and the Japanese firm Human Holdings (96th). Five US companies were also added to the list; and AirSwift entered the list at number 42, following the merger of Air Energi and Swift Worldwide Resources.

“The list represents the global nature of the industry,” said Adam Pode, Director of Research for EMEA & APAC at SIA. “We have firms from sixteen nations in the list, who operate in all the major markets and such countries as Albania, Iraq and Vietnam.”

A total of ten companies fell out of the rankings this year due to revenue size (3), acquisition (5) or based on additional insights related to earnings (2). 

Among the top 100 firms, 44 on the list are headquartered in EMEA, 43 in North America and 13 in Asia. Thirty-four of the largest firms are publicly listed. Five Executive Search firms are included in the ranking, with Spencer Stuart and Korn Ferry in leading positions respectively for this niche.
