What the number is, and is not

A company is on this page when AngelEQ can point to Fortnox at that company with confidence, and only while it is an active Swedish company. Two honest limits. First, this is not Fortnox's own customer count, which is larger; it is the part of the base AngelEQ has identified, which is also exactly the part you can filter on. Second, companies switch systems, so AngelEQ refreshes the platform data regularly and dates every entry. The number you filter on is the number you can defend in a sales conversation.

By county

Stockholm, Västra Götaland and Skåne hold 20,260 of the 36,059 companies, roughly in line with where Swedish companies are. Fortnox is a nationwide system; the county filter matters because your territory is not nationwide.

Companies registered without a Swedish county are not in the table, so the rows sum to slightly less than the headline.

By industry

Industry per the company's primary SNI 2025 division (how SNI codes work). Real estate, specialised construction and consultancies lead, which is the typical profile of an owner-run Swedish company.

By company size

Registered employee band. The installed base is overwhelmingly small companies, which is what you would expect from Fortnox's market, and a useful sanity check that the page is describing the right kind of company.

What partners, integrators and competitors do with it

"Our best customers run system X" is one of the most common segment definitions in Swedish B2B, and one of the hardest to turn into a list. Fortnox partners and app developers want the base to sell into. Integrators want companies on a platform they already connect to. Competing systems want companies at the size where they usually switch.

In AngelEQ the platform is a filter over the complete Swedish company register, so "construction companies in Västra Götaland with 10 to 49 employees that run Fortnox" is one question. The list comes back with filed financials and named decision-makers on each company, ready to export, or pulled straight into Claude or ChatGPT through the MCP connector. Have a list of your own to check against? Enrich it and the platform column fills in.
