The companies in Vantaa are primarily established firms in manufacturing and services, with a focus on industrial and technical solutions. Among them are Caverion, a provider of sustainable built environments, Finnair, an airline connecting Europe, North America, and Asia, and Fazer, a food company with a 130-year heritage. Vaisala specializes in weather and environmental measurements, while Cramo offers equipment rental services.
A notable pattern is the strong presence of companies with long histories; several were founded in the late 19th or early 20th century, indicating a mature industrial base. These include Fazer (1891), Finnair (1923), and Tikkurila (1862), alongside newer firms like Fortaco Group (2012) and iCare (2003).

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.
