In 2025, Buy Now Pay Later (BNPL) platforms are no longer just payment tools—they are full-scale fintech ecosystems.
They now combine payments, consumer credit, merchant analytics, shopping discovery, loyalty programs, and financial services into a single experience, allowing platforms to own more of the transaction lifecycle and user relationship.
At the center of this shift is Klarna, which has transformed short-term credit into a multi-billion-dollar global business.
Beyond installments, Klarna monetizes merchant fees, consumer financing, subscriptions, advertising, and banking products, positioning itself as both a payments provider and a commerce platform embedded in everyday shopping.
For founders, Klarna’s revenue model is a masterclass in monetizing both sides of a marketplace while managing risk at scale.
It demonstrates how data-driven credit scoring, diversified revenue streams, and repeat-user economics can reduce default risk, improve margins, and create sustainable fintech growth even in regulated environments.
