How do you go from pitching Sequoia to ringing the bell on a US IPO?
Sebastian Siemiatkowski, co-founder and CEO of Klarna was raised in a home where ambition met accountability. Even as Klarna thrived in Sweden, his parents reminded him: “That’s fantastic. When are you going to get your degree?”
That grounding, paired with Sebastian’s own ambition to measure up to companies like Google and Facebook, pushed Klarna beyond local success to a global stage.
In this episode, we also get into:
• how sci-fi books inspired him to see entrepreneurship as an adventure
• how Klarna brought Sequoia on board
• how Klarna got ahead of Afterpay in the U.S market
• navigating co-founder tensions and pivoting leadership
• turning Sweden’s strict bill collection into Klarna’s advantage
