Half of them were founded in 1996 or later. The most common headquarters are London (7), New Delhi (5) and San Francisco (5).

🌍 World100 companiesUpdated Nov 12, 2026

These companies are large and mid-sized firms focused on human resources and recruitment services. Most are global or operate across multiple countries, with a few notable exceptions that serve specific national or regional markets. This list includes companies like Randstad, which provides workforces and HR advice, and Adecco, a top provider of HR solutions matching talent with job opportunities. ADP focuses on improving workplace experiences through advanced HR products, while ManpowerGroup sources and assesses talent globally. Also listed is Hays, a specialist in recruitment and workforce solutions, and Quess Corp Limited, an integrated business service provider.

The headquarters of these companies are spread across several continents, indicating a global distribution rather than a concentration in one geographical area. For example, Randstad is based in Diemen, Netherlands, Adecco in Zurich, Switzerland, and ADP in Roseland, USA. Other headquarters include London, UK, for WTW and Hays, and Bengaluru, India, for Quess Corp Limited. This diversity in headquarters locations suggests a widespread presence of major players in the human resources and recruitment sector.

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 12, 2026.
