AI·KlarnaKlarna and Google CEOs are vibe coding—a skill that could help you land your next jobBy Marco Quiroz-GutierrezBy Marco Quiroz-GutierrezReporterMarco Quiroz-GutierrezReporterRole: ReporterMarco Quiroz-Gutierrez is a reporter for Fortune covering general news.SEE FULL BIO Sebastian Siemiatkowski, chief executive officer and co-founder of Klarna Holding ABMichael Nagle—Bloomberg via Getty ImagesVibe coding has made it to the C-suite, and executives say it is saving them huge amounts of time.
Klarna CEO Sebastian Siemiatkowski has never been a grammer, but thanks to AI’s rapid development he is now taking the initiative to code his own jects.
Vibe coding, which refers to using AI to gram using natural language, is helping even non-nical workers spin up ideas.
“Rather than disturbing my poor engineers and duct people with what is half good ideas and half bad ideas, now I test it myself,” he recently said on the Sourcery podcast.
“I come say, ‘Look, I’ve actually made this work, this is how it works, what do you think, could we do it this way?'” Siemiatkowski cofounded his buy-now-pay-later platform in 2005, and said for the past 20 years he’s been doing his own version of vibe coding by giving instruction to his engineers and duct people and then reviewing the totype he pitched weeks later.
With tools Cursor, though, Siemiatkowski said he can bring his ideas to life on his own, before bringing them to the larger team.
This way, he said, he can avoid the mixups that used to happen when the team’s totype didn’t align with his vision.
Instead of waiting weeks for results, Siemiatkowski said he can vibe code a totype in 20 minutes. The cess is so easy, the Klarna CEO admitted he has gotten a bit obsessed.
“My wife is a bit frustrated with me because whenever the kids went to bed this summer I was just ‘Cursor. I got to code,’” he said.
To be sure, some developers have claimed that fixing the mistakes in AI-generated code can be a chore in and of itself.
An August report by content dery platform Fastly found 95% of around 800 software engineers surveyed spend extra time looking over AI-generated code.
Some developers have said AI can be helpful for routine tasks and smaller blems but struggles to handle more complex tasks.
On the day of Klarna’s debut on the New York Stock Exchange last week, the company’s stock shot up by 15%. Its stock was up 3.4% as of midday Monday.
Siemiatkowski has recently led Klarna to move beyond its BNPL roots to become more of a traditional bank with moves a debit card partnership with Visa announced in June.
Siemiatkowski has also pushed the company to dig in on AI, even using the nology to create a digital clone of himself that announced Klarna’s first quarter results earlier this year.
Other bigwigs Google CEO Sundar Pichai have also started experimenting with vibe coding using AI tools.
Pichai, who has a background in engineering, said in June he had also been experimenting with Cursor and another tool, Replit, to create a webpage.
“It’s exciting to see how casually you can do it now,” Pichai said at Bloomberg in San Francisco, according to Insider.
“Compared to the early days of coding, things have come a long way.” Fortune Global Forum returns Oct. 26–27, 2025 in Riyadh.
