The multinational companies in Linz are primarily large, established firms in industrial sectors, with a significant presence in manufacturing, construction, and banking. Swietelsky AG is a construction company, Johannes Kepler Universität Linz is a higher education institution, voestalpine is a global steel and technology group, and Raiffeisenlandesbank Oberösterreich AG is a regional bank.

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.
