The aerospace and defense sector in Finland is characterized by a mix of established institutions and younger, specialized technology firms. Puolustusvoimat - Försvarsmakten - Finnish Defence Forces, founded in 1918, provides national defense. Patria, established in 1921, offers military equipment and pilot training. ICEYE, founded in 2015, specializes in SAR satellite constellations. Valmet Automotive, from 1968, focuses on e-drive engineering, and Bittium, founded in 1985, on secure communications.
A notable pattern is the presence of several IT and engineering service companies that support the broader industrial and defense sectors. Gofore and Unikie, both founded in the 2000s, are IT consulting firms based in Tampere. Insta, founded in 1960, is an engineering services provider also located in Tampere. This suggests a strong ecosystem of digital and engineering support for the manufacturing and defense industries in Finland.

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 14, 2026.
