Sweden's buy now, pay later giant Klarna initially embraced AI to cut costs, reducing customer service expenses by 40% and replacing 700 agents with OpenAI-powered chatbots. However, by 2025, declining customer satisfaction forced CEO Sebastian Siemiatkowski to admit they had overemphasized cost-cutting. While AI efficiently handled standard inquiries in multiple languages, it lacked the empathy needed for complex issues. Klarna has now reversed course, hiring human agents to complement AI capabilities. This experience highlights important lessons for the industry: AI can dramatically reduce operational costs but struggles with emotional intelligence, excessive automation risks customer trust, and a hybrid approach balancing technology with human touch may provide the optimal service model as Klarna prepares for potential public listing.
