# List of professional services firms in Sweden

Tamtam tracks 194 professional services firms headquartered in Sweden. This list ranks the 50 largest by number of employees on LinkedIn, led by Sweco, AFRY and BTS. Their median headcount is 1,296. Half of them were founded in 1995 or later. The most common headquarters are Stockholm (36), Gothenburg (4) and Malmö (2).

The professional services sector in Sweden is represented by a concentration of large firms, predominantly headquartered in Stockholm. These companies offer a range of specialized services, from engineering and design to financial and business consulting. For instance, Sweco focuses on sustainable urban solutions, while AFRY provides engineering and advisory services across various sectors. BTS helps organizations with strategy execution, and Intrum specializes in credit management. Another example is ÅF, an international leader in engineering and design, and WSP i Sverige, which develops cities and transport systems.

A notable pattern among these professional services firms is their strong focus on sustainability and digitalization. Many companies, such as Sweco, AFRY, and ÅF, explicitly mention their commitment to sustainable solutions and digital innovation. The vast majority of these larger firms are based in Stockholm, with only a few exceptions like Sigma Group in Malmö and Propia AB in Norrköping, indicating a significant centralization of the professional services industry in the capital.

## 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.
