This selection of European firms includes large professional services networks and global law firms. KPMG Italy provides audit, advisory, tax, and legal services, while Mazars offers audit, accountancy, advisory, tax, and legal services. Clifford Chance and Freshfields are global law firms advising corporations and financial institutions. TMF Group provides administrative, financial, and legal support internationally.
The companies listed are predominantly large, established organizations, with several founded in the mid-20th century or earlier, such as Mazars (1945) and Freshfields (1743). A notable pattern is the concentration of headquarters in major financial centers, particularly London, which hosts several of the largest law firms.

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 14, 2026.
