These Swedish online-only businesses are primarily mid-sized firms, with a notable presence in entertainment, retail, and financial services. Companies like King, with 6555 employees, are known for mobile games such as Candy Crush. Avanza Bank provides low-cost banking and investment services, while Mathem offers online grocery shopping. Sellpy focuses on second-hand retail to promote a circular economy.
A significant cluster of these companies, including King, Avanza Bank, and Mathem, are headquartered in Stockholm. This indicates a concentration of online business activity in the capital. The companies demonstrate a mix of established firms founded in the late 1990s and early 2000s, like King (2003) and Avanza Bank (1999), alongside younger ventures such as Kamar Pelajar (2017) and Mai (2022).

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 12, 2026.
