Upper Austria is home to multinational companies with a strong focus on manufacturing and industrial technology. Key players include Fronius, which manufactures battery charging systems and solar electronics, and TGW Logistics, specializing in automated fulfillment centers. Greiner is a global supplier of plastics and foam solutions, while ENGEL is a leader in injection moulding machines. BWT Group is a European leader in water technology, and Lenzing Group creates solutions from natural wood fibers. These firms represent a mix of established industrial groups and specialized technology providers.

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.
