# Top 30 corporate groups and holding companies in Warsaw

Tamtam tracks 49 corporate groups and holding companies headquartered in Warsaw. This list ranks the 30 largest by number of employees on LinkedIn, led by PZU, Poczta Polska S. A. and Erste Bank Polska. Their median headcount is 844. Half of them were founded in 1993 or later.

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 Sprzęt 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. Examples include Grupa Wirtualna Polska (1995) and Agora SA (1989), both prominent media entities, alongside Benefit Systems SA (2000) in employee benefits and PKP CARGO S.A. (2001) in logistics.

## 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.
