# Top 100 professional services firms in Germany

Tamtam tracks 690 professional services firms headquartered in Germany. This list ranks the 100 largest by number of employees on LinkedIn, led by Allianz Services, DEKRA and Bilfinger. Their median headcount is 1,493. Half of them were founded in 1987 or later. The most common headquarters are Berlin (13), Stuttgart (11) and Munich (10).

These German professional services firms primarily consist of large enterprises offering a broad spectrum of specialized services. Key players include Allianz Services, which provides core insurance operations and consulting, and DEKRA, known for its global safety services like vehicle inspection and industrial certifications. TÜV SÜD also offers extensive testing and advisory services, while Bilfinger specializes in industrial services for process industries. The list features a strong presence of IT services and consulting firms like Bechtle, GFT Technologies, T-Systems International, and msg, alongside major auditing and consulting firms such as PwC Deutschland and KPMG Deutschland. Engineering services are also well-represented by companies like EDAG Group, IAV GmbH, and Bertrandt Group.

A notable pattern among these companies is their wide geographical distribution of headquarters across Germany, including major financial hubs like Frankfurt, industrial centers like Stuttgart and Mannheim, and technological hubs such as Munich and Berlin. This indicates a decentralized yet robust professional services landscape. Many of these firms, such as TÜV SÜD (founded 1866) and several IT companies founded in the 1980s, have a long-standing history, reflecting established expertise in their respective fields.

## 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.
