These Swedish companies are primarily large and mid-sized firms operating in the energy sector, encompassing utilities, renewable energy, and industrial machinery manufacturing. Key players include Vattenfall, a European energy company striving for fossil freedom, and Stena AB, a family-owned conglomerate with interests in shipping and offshore drilling. NIBE Group offers sustainable energy solutions, while Northvolt focuses on sustainable battery manufacturing.
A notable pattern is the strong presence of companies involved in forest products and bioenergy, such as SCA, a major private forest owner, and Södra, a forestry-based economic association. This highlights Sweden's focus on leveraging its natural resources for energy and industrial purposes.

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.
