This selection of large companies in Warsaw highlights a diverse corporate landscape, with a notable presence of established entities in key sectors. Companies like PZU, a major insurer founded in 1803, and Poczta Polska S.A., the national postal operator since 1558, demonstrate a long-standing industrial heritage. The list also includes financial services through Erste Bank Polska, and utilities such as PGE Polska Grupa Energetyczna, the largest electric utility in Poland. Manufacturing is represented by BSH Sprz臋t Gospodarstwa Domowego Polska, a household appliance manufacturer, and pharmaceuticals by Adamed Pharma.
A significant pattern observed is the strong representation of companies founded in the late 20th and early 21st centuries, particularly in media and technology.

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.
