Klarna CEO’s 20-Year AI Joyride Ends in $15B IPO Rush
Sebastian Siemiatkowski, Klarna’s CEO and self-described '20-year vibe coder,' traded his meeting room megaphone for AI Cursor, cutting prototype wait times from 'weeks' to a magician’s 20 minutes. With a backstory of being a business guy turned accidental coder, he turned AI into a shield to spare poor engineers from his 'half good, half bad ideas.' Klarna popped 30% above a $40 IPO share price last week, hitting $52, and tossed $15 billion on the NYSE bonfire, letting employees cash out early by skipping the usual lockup prison. Meanwhile, Google’s Sundar Pichai and Amazon’s new AI approvals make vibe coding the new job crush, proving it’s not just for Silicon Valley hipsters anymore.
