Company History
Founded 2005 in London, United Kingdom
In 2005, Sebastian Siemiatkowski pitched the idea that became Klarna at a Stockholm School of Economics entrepreneurship competition. The judges ranked it last. He founded it anyway with Niklas Adalberth and Victor Jacobsson, operating first under the name Kreditor. The original product was a single-click invoice payment system for Swedish e-commerce — buy the item, receive it, then pay the invoice within 14 days. The credit risk sat entirely with Klarna. The bet was that most consumers would pay, and that merchants would accept a 3-6% fee in exchange for not managing their own collections. Both bets proved correct. The company rebranded to Klarna in 2009 and expanded the product beyond invoicing to include installment payments and direct bank transfers. The 2013 acquisition of SOFORT, the German direct bank transfer service, gave Klarna immediate penetration into German-speaking markets where consumer credit skepticism made invoice products more appealing than card-based lending. The 2021 peak valuation of $45.6 billion reflected pandemic-era e-commerce acceleration and a market that priced BNPL growth as if the credit cycle had been repealed. It had not been. By 2022, rising interest rates increased Klarna's cost of funding while consumer credit quality deteriorated simultaneously. The company cut 40% of its workforce in a single announcement — a move that shocked the European startup ecosystem but ultimately preserved the balance sheet. Klarna emerged from that contraction with a smaller cost base, a banking license, and a path to profitability that the company validated with $21 million in net income in fiscal year 2024 before reporting a $273 million net loss in fiscal year 2025.
Klarna possesses a rebellious, millennial founding story, rooted in the prestigious academic environment of Sweden but defined by a brutal, rejection by the traditional financial establishment. The company was founded in 2005 in Stockholm, Sweden, by Sebastian Siemiatkowski, Niklas Adalberth, and Victor Jacobsson. The three ambitious founders met while studying at the prestigious Stockholm School of Economics. They possessed a foundational 'eureka' moment: buying things online was painful, insecure, and often required consumers to enter sensitive credit card information on sketchy websites. They entered the annual entrepreneurship pitch competition at their university with a disruptive idea: a service that allowed the consumer to receive the physical goods *before* they paid for them (assuming the credit risk on behalf of the merchant). In a legendary, humiliating moment, the panel of esteemed Swedish banking executives destroyed their pitch, telling them it was a terrible, dangerous idea that would never work. infuriated but motivated, they ignored the bankers and founded Klarna (which means 'clear' in Swedish) anyway. Their foundational masterstroke was absorbing the friction of online checkout. By heavily focusing on intuitive user design (the famous 'smoooth' pink branding) and partnering with retailers, they bypassed the traditional, clunky banking infrastructure. Siemiatkowski's intense, immensely driven leadership transformed a rejected university project into a multi-billion dollar global fintech juggernaut, reshaping how a generation of consumers interacts with credit.
Niklas Adalberth co-founded Klarna in 2005 alongside Sebastian Siemiatkowski and Victor Jacobsson, serving as the company's Deputy CEO and driving its early international expansion into Germany and the United Kingdom. After leaving Klarna in 2016, Adalberth founded Norrsken Foundation, the world's largest foundation dedicated to supporting impact-driven entrepreneurs, leveraging the wealth generated from his Klarna stock options. His tenure at Klarna was marked by a relentless focus on regulatory compliance and banking partnerships, recognizing early that the company would eventually need to operate as a licensed financial institution to survive long-term. Adalberth's legacy at Klarna is defined by his ability to bridge the gap between aggressive Silicon Valley-style growth tactics and the conservative, risk-averse nature of European financial regulation.
Victor Jacobsson co-founded Klarna in 2005, bringing the technical expertise required to build the complex financial infrastructure that underpinned the company's invoice factoring model. As the early CTO Jacobsson was responsible for creating the proprietary underwriting algorithms that analyzed thousands of data points to assess consumer creditworthiness in milliseconds, a technological advantage that allowed Klarna to offer instant credit decisions at a time when traditional banks required days of processing. He left the company in 2010 to pursue other ventures, but his foundational work on the risk engine remains the core of Klarna's competitive advantage, enabling the company to process millions of transactions daily with industry-leading fraud detection rates. Jacobsson's contribution established Klarna as a technology-first financial institution, rather than a traditional bank with a website.
