The professional services sector in Austria is characterized by a mix of large, established firms and mid-sized companies. These firms primarily offer consulting, financial, legal, and IT services. Notable companies include TÜV AUSTRIA Group, a testing and certification company; KPMG Austria, a major audit and consulting firm; BE-terna, specializing in ERP and CRM solutions; and Wolf Theiss, a prominent law firm in the CEE/SEE region. Many of these companies have a strong international presence, serving clients across Europe and globally.
A clear pattern among these firms is the concentration of headquarters in Vienna, which is home to many leading professional services providers. While a few companies are in industrial engineering or environmental services, the majority are in business consulting, financial services, and IT consulting. The founding dates span from the late 19th century to the early 2000s, indicating both a long-standing tradition and newer entrants in the market.

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 11, 2026.
