# The 50 largest companies with in-house R&D in Finland

Tamtam tracks 177 companies with in-house R&D headquartered in Finland. This list ranks the 50 largest by number of employees on LinkedIn, led by Nokia, KONE and Metso. Their median headcount is 2,810. Half of them were founded in 1936 or later. The most common headquarters are Helsinki (20), Espoo (15) and Turku (5).

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. Many of these companies, such as Nokia and Wärtsilä, have long histories, indicating established players in their respective fields.

A clear pattern among these R&D-intensive firms is their geographical concentration. Espoo and Helsinki emerge as primary headquarters locations for many of the largest entities. This suggests a clustering of major industrial and technological R&D efforts within these key Finnish cities, fostering a localized ecosystem for innovation and development.

## 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.
