Klarna's CEO says he uses vibe coding tools to save his engineers and product managers time

In a recent episode of the Sourcery podcast, Sebastian Siemiatkowski, the CEO of Klarna, shared his enthusiasm for AI coding tools, particularly highlighting their impact on his company’s development processes. Siemiatkowski, who transitioned from a business-focused background to exploring coding with tools like Cursor, emphasized how these innovations have drastically accelerated prototyping and reduced the workload on his engineering teams. Reflecting on his experience, the CEO revealed that his approach to prototype development has evolved significantly over the last two decades. Previously, he would communicate his ideas during meetings, waiting weeks for engineers to produce a prototype. "Now, I'm able to create a working prototype in just 20 minutes using AI," he stated, illustrating the remarkable efficiency gains. Siemiatkowski also noted the benefits of AI in managing his interactions with staff. Instead of burdening his engineers and product managers with a mix of ideas, he can now test concepts independently. He explained, "I can show them a working example and ask for their input on improvements, making our collaboration more effective." Klarna made headlines recently by going public on the New York Stock Exchange, achieving a remarkable 30% increase on its first day, with shares rising from an initial offering price of $40 to $52. In a unique move, the company announced it would convert vested restricted stock units into tradable shares, allowing employees to sell them shortly after the $15 billion IPO. As the trend of vibe coding gains momentum in the tech industry, notable leaders like Google’s Sundar Pichai have also endorsed its value. While some industry professionals express concerns about the potential trivialization of coding tasks, the surge in demand for AI-assisted coding skills is evident, with major firms like Amazon and Visa incorporating these capabilities into their hiring criteria.
