Klarna made its New York stock exchange debut this week, sending its market cap soaring to $15 billion-propelling around 40 staffers to millionaire status overnight, with its executive team gaining the most from the IPO. It's not the first time Klarna's success has created ultra-rich employees-at least 115 of the business' workers have hit seven-figure net worths since 2021. And staffers at other tech companies, including Nvidia, Canva, and Palantir who invested early have also made it to the exclusive wealth club.
