Fiken (Fiken AS, Oslo, founded 2014) is Norway's most popular do-it-yourself cloud accounting tool for sole proprietorships (enkeltpersonforetak) and small limited companies (aksjeselskap). It bundles bookkeeping, invoicing, bank reconciliation, VAT/MVA reporting, payroll with a-melding, annual accounts and the tax return into one flat monthly fee — from 229 NOK/mo (€20) for sole traders and ~349 NOK/mo for an AS, after a 30-day free trial. There is no permanent free tier. The product is praised for radical simplicity and a strong public REST API (api.fiken.no) widely used by Norwegian fintech integrations, banks and accountants. Crucially for a sovereignty audit, Fiken is one of the rare profitable, fully founder-owned European SaaS companies: the three founders — Bendik Gill Bakken (CEO), Joakim Blomskøld and Aleksander Blomskøld — still hold ~33.33% each, with no PE, VC or US capital on the cap table (Finansavisen reported in April 2025 that the trio had each become NOK-billionaires on the business; ~87 employees, ~375M NOK 2024 revenue). Primary data is hosted in Norway, partly to satisfy the Norwegian Bookkeeping Act, in a datacenter the company says is ISO 27001:2013 / ISO 9001:2015 certified. The caveat is the sub-processor stack: the published databehandler list names AWS, Microsoft and Google for backup, OpenAI for AI assistance, plus a long tail of US SaaS (Intercom, Freshdesk, Mailchimp, Twilio, Sentry, New Relic, Slack, Notion, Meta), all under SCCs. The UI is Norwegian-only, so practical reach is the Norwegian market rather than pan-EU.
