Background
Sebastian Siemiatkowski co-founded Klarna in Stockholm in 2005 and has served as CEO ever since, building it into one of Europe's most prominent buy-now-pay-later companies. A vocal technology optimist, he positioned Klarna as a flagship example of AI-first enterprise transformation, frequently citing efficiency gains to justify deep staff cuts.
In 2023, Siemiatkowski replaced roughly 700 human customer service agents with AI, declaring the experiment a success. By early 2026, the strategy had backfired: satisfaction scores fell, customers reported robotic responses and Kafkaesque support loops, and Siemiatkowski publicly admitted he had gone too far. Klarna began rehiring human agents to restore service quality.
His reversal has become a defining case study in the limits of wholesale AI automation. The tension is stark: Siemiatkowski championed AI replacement loudly and publicly, making the climbdown equally visible. The episode has sharpened debate about whether AI improves or degrades customer experience at scale, and at what human cost.
