The e-commerce companies in Masovia include a mix of large, established Polish firms and newer digital-focused businesses. Key players are Poczta Polska S. A., the national postal operator, and retail chains like Castorama Polska Sp. z o.o., specializing in home improvement, and Empik Group, a broad retail group. Other notable companies are Grupa Wirtualna Polska, a digital media and technology company, and Cyfrowy Polsat S.A., a telecommunications and media leader.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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.
