# List of professional services firms in Antwerp
Tamtam tracks 49 professional services firms headquartered in Antwerp. This list ranks the 30 largest by number of employees on LinkedIn, led by QbD Group, Copus and GRITT. Their median headcount is 306. Half of them were founded in 2003 or later.
Antwerp's professional services sector features a mix of well-established firms and younger companies, predominantly in human resources, IT, and business consulting. Notable firms include QbD Group, which supports life science companies, and Vanbreda Risk & Benefits, an insurance broker. HR services are well-represented by Copus, which focuses on matching skilled talent, and Synergie Belgium, with its wide network across Belgium.
A significant pattern among these companies is their focus on providing specialized expertise and outsourced solutions. Many, like GRITT and TEC, offer technical outsourcing and engineering consultancy. The presence of several staffing and recruitment agencies, such as Talentus and Vivaldis, further highlights Antwerp's role as a hub for human capital solutions.

## 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.
