The companies listed are large Finnish corporations with significant in-house research and development operations. They span various sectors, with a strong presence in industrial machinery, telecommunications, and manufacturing. Notable examples include Nokia, a B2B technology leader in digital networks; KONE, a global leader in elevators and escalators; Wärtsilä, providing technology and services for sustainable societies; and UPM, a global provider of renewable fibers and materials.

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 12, 2026.
