This selection of Swiss firms primarily comprises large to mid-sized professional services and financial services companies. These firms offer a range of expertise including audit, tax, advisory, and wealth management solutions. PwC Switzerland, KPMG Switzerland, and BDO Switzerland are prominent examples, focusing on comprehensive audit, advisory, and consulting services for diverse client bases. ZEDRA specializes in wealth management and corporate services, while OBT AG provides extensive consulting in trust, IT, tax, and legal matters. Forvis Mazars in Switzerland offers integrated audit, accountancy, and advisory services.
A notable pattern among these companies is the concentration of headquarters in major economic hubs.

Geneva is home to Forvis Mazars in Switzerland and Moore Stephens Refidar SA, while Zug hosts KENDRIS and inVersa Consulting AG.

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 12, 2026.
