The Finnish corporate landscape features large groups with diverse operations, many of which are headquartered in Helsinki. Notable examples include UPM, a global provider of renewable fibres and advanced materials, and S-ryhmä / S Group, a cooperative network operating retail stores, services, and hospitality. OP Pohjola is the largest Finnish financial group, while Kesko - K-Group is a leading trading sector company.
Further demonstrating this diversity are companies such as Mehiläinen, a significant social and healthcare service provider, and Outokumpu, a global leader in sustainable stainless steel production. A clear pattern is the strong concentration of headquarters in the Helsinki metropolitan area, including Espoo and Vantaa, indicating a central hub for major Finnish corporations.

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.
