What Flatpay does
Flatpay is a Danish fintech founded in 2022 that delivers payment acceptance and point-of-sale (POS) infrastructure to small and medium-sized merchants across Europe. The company combines proprietary payment terminals and POS software with an online payment gateway built on the Frisbii (formerly Billwerk) platform, and it supports mobile wallets (Apple Pay, Google Pay), MobilePay, Vipps, and major card schemes. The terminal app supports seven languages and offers staff PIN management, tipping/refunds, and Wi-Fi connectivity, and Flatpay is PCI DSS compliant with encryption- and tokenization-based security. As of 2026 the platform serves more than 70,000 merchants in Denmark, Germany, Finland, Italy, France, the United Kingdom, and the Netherlands, with an eighth European market entry planned for 2026; Germany is currently the largest market.
The business is built on a deliberately simplified commercial model: a single flat transaction rate of 0.99% on all card types for in-store payments, 0.99% (EU/Danish) and 1.99% (non-EU and corporate) for online transactions, and no monthly subscription or fixed per-transaction fees. Settlement is daily, which differentiates Flatpay from acquirers with multi-day cycles. Revenue streams include card transaction fees, online/e-commerce transaction fees, hardware replacement and minimum-turnover fees (€50 unfulfilled turnover fee, €480 terminal replacement, €1,000 POS replacement), and — via wholly-owned subsidiary Flatpay Financial Services A/S — Flatpay Capital, a revenue-based financing product powered by Liberis that takes a percentage of daily card sales as repayment. Distribution is direct: Flatpay.com localized country storefronts, a self-serve savings calculator, in-person field sales, on-site installation, and 24/7 local-language support.
Flatpay was co-founded by Sander Janca-Jensen (CEO), Peter Lüth, and Rasmus Busk, and is headquartered in Herlev, Denmark. The company has raised approximately €205M across four disclosed rounds — DKK 26M seed (Seed Capital, October 2022), €15M Series A (2023), €45M Series B led by Dawn Capital (April 2024), and €145M Series C co-led by AVP and Smash Capital (November 2025) — reaching a €1.5B / $1.7B valuation and unicorn status in November 2025, the fastest such milestone for a Danish company. As of mid-2026 the workforce had grown to roughly 2,000 employees at a pace of 100+ new hires per month, and the company has announced forthcoming merchant banking services (business accounts, expense management) as the next leg of its product expansion.
