These Dutch professional services firms are predominantly large, established companies, with the earliest founded in 1881 and many others in the mid to late 20th century. While Randstad, with 653,000 employees, specializes in human resources, other firms offer a range of services. Arcadis (42,295 employees) focuses on design and engineering, TMF Group (11,186 employees) provides financial and legal support, and Getronics (4,147 employees) delivers IT solutions.
A notable pattern is the concentration of headquarters in and around Amsterdam, including Amsterdam itself, Amstelveen, and Diemen. Additionally, staffing and recruiting is a prominent sector among these companies, with Randstad, RGF Staffing NL, RGF Staffing, and Brunel all operating in this field.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
