Klarna CEO: AI “vibe coding” builds prototypes in 20 minutes, reshaping engineering value
Klarna CEO Sebastian Siemiatkowski says AI-driven “vibe coding” — using natural-language prompts with LLMs and tools like Cursor — lets executives spin up functional prototypes in ~20 minutes instead of weeks. By testing ideas himself, he reduces interruptions for engineers. The approach is becoming a core skill for tech leaders and changing how companies and VCs value engineering talent. Klarna also recently debuted on the NYSE.
