🇵🇱 Katowice50 companiesUpdated Nov 11, 2026

These Katowice-based companies are primarily large organizations, particularly prominent in banking, higher education, and logistics. Notable examples include eSky Group, a travel booking platform; ING Poland, offering financial services; the University of Silesia in Katowice, a public university; and Grupa TAURON, an electricity and heat producer. Many of these firms are well-established, with several founded before 2000, indicating a mature business landscape.

A significant pattern in these companies is the strong presence of the financial and educational sectors. ING Poland and ING Hubs Poland represent a substantial banking cluster, while the University of Silesia, Medical University of Silesia, and Uniwersytet Ekonomiczny w Katowicach highlight a robust higher education segment, all headquartered within the city.

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.
