Oslo's subscription business landscape features a diverse mix of established enterprises and younger firms. Companies like DNB, a major financial services group, and Visma, a provider of business software across Europe and Latin America, represent large-scale operations. Media production is also prominent, with Amedia, Norway's largest publisher, and VG - Verdens Gang AS, a leading daily newspaper, both headquartered in the city.
A notable pattern among these companies is their strong focus on information and digital services. Rystad Energy provides data and insights for global energy markets, while Mercell operates a digital procurement marketplace. Many of these firms, such as Visma (founded 1996) and Gelato (founded 2007), were established in the late 20th and early 21st centuries, indicating a period of significant growth in digital and service-oriented businesses.

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.
