V ictor Jacobsson is a Swedish billionaire who is one of the three co-founders of Klarna, a major global financial technology company that is a leader in the "buy now, pay later" (BNPL) industry. He co-founded the company in 2005 with his two partners, Sebastian Siemiatkowski and Niklas Adalberth, while they were all students at the Stockholm School of Economics. Their idea was to create a simpler and safer way for consumers to shop online, by allowing them to receive their goods before they had to pay for them.

This BNPL model proved to be massively popular, and Klarna has since grown into a fintech giant with millions of users and a partnership with a huge number of online retailers around the world. The company's soaring private valuation, backed by major global investors, has turned the three founders into billionaires. While he is no longer involved in the day-to-day management of the company, his founding stake is the source of his massive fortune. He is now a private investor.
