How Swedish Fintech Klarna Leveraged AI to Halve Its Workforce and Double Revenue
Over the last three years, Klarna, a leading Swedish fintech firm, has dramatically transformed its operations by integrating artificial intelligence (AI), resulting in a 50% reduction in staff while simultaneously doubling its revenue. This remarkable shift highlights the accelerating influence of AI technologies on the financial services sector.
From Startup to AI-Driven Powerhouse
Founded in 2005, Klarna pioneered the “buy now, pay later” (BNPL) model, revolutionizing how consumers finance online purchases. Initially focused on managing credit risk for e-commerce merchants, the company has since expanded its offerings globally. By the third quarter of 2025, Klarna reported revenues of $903 million-more than twice the amount recorded in the same period of 2022. Transaction volumes processed through Klarna’s platform exceeded $33 billion during this quarter alone.
Strategic Workforce Optimization Through AI
While Klarna’s revenue surged, its employee count shrank from approximately 5,500 in 2022 to under 3,000 by late 2025. This reduction was not due to layoffs alone but largely driven by natural attrition, with AI systems stepping in to fill the operational gaps. The company adopted the enterprise version of ChatGPT in 2023, empowering staff with generative AI tools that enhanced productivity and automated routine tasks. According to industry reports, AI now performs the equivalent work of over 850 full-time employees within Klarna.
AI as a Catalyst for Sustainable Growth
Klarna’s leadership emphasizes that the company’s future growth hinges on AI-driven efficiency and its expanding global network. CEO and co-founder Sebastian Siemiatkowski remarked, “We are entering a new era-not just as a publicly traded company on the New York Stock Exchange, but as the world’s first truly AI-powered global digital bank.” He further noted a significant paradigm shift in knowledge-based industries, driven by AI adoption.
Looking ahead, Klarna projects revenues exceeding $1 billion in the upcoming quarter, underscoring the scalability of its AI-enhanced business model.
Regulatory Milestones and Market Position
In 2017, Klarna secured a full European Union banking license from Finansinspektionen, the Swedish Financial Supervisory Authority, marking a critical step in its evolution. At that time, the company’s valuation stood at $2.25 billion; today, it is estimated to be worth around $17 billion.
A key innovation was the introduction of a feature within Klarna’s app allowing users to split payments for online purchases at any retailer, popularizing the BNPL concept. While first launched in Sweden, Australia, and the US, this functionality was rolled out in the UK in 2021, contributing to the widespread adoption of BNPL services worldwide.
Industry Impact and Competitive Landscape
Fintech analyst Chris Skinner, CEO of The Finanser, credits Klarna with inventing the BNPL model. However, the market has become increasingly competitive, with major players like Apple and traditional banks entering the space. UK Finance recently reported that by 2024, one in four UK adults will use BNPL services, up from 14% just a year prior, reflecting rapid consumer adoption.
Skinner points out that despite Klarna’s pioneering role, maintaining market leadership is challenging amid intensifying competition. The company must continue innovating to sustain its momentum in a sector it helped create but no longer dominates.
