Klarna
Stockholm, Sweden · StartupKlarna is a Swedish fintech company that pioneered the “buy now, pay later” (BNPL) model globally. Founded in 2005 by Sebastian Siemiatkowski, Niklas Adalberth, and Victor Jacobsson, Klarna started by offering online shoppers in Sweden a way to purchase goods on invoice (pay after delivery). Over the next decade, the company expanded across Europe and beyond, becoming a dominant online payments provider. As of 2021, Klarna was Europe’s highest-valued private tech company at $45.6 billion, reflecting meteoric growth fueled by consumers’ appetite for installment payments. Klarna’s app and services allow users to split purchases into interest-free installments or pay later, and it partners with over 450,000 retailers worldwide, including global brands like H&M, IKEA, and Nike. The company has over 150 million users across 45 countries and handled $80 billion in transaction volume in 2021. Klarna’s journey, however, has seen dramatic swings: after reaching a $45B valuation in mid-2021, a combination of rising interest rates and tech market downturn led to a downround in 2022, cutting its valuation to $6.7 billion (an 85% drop). The company restructured, laying off 10% of its staff, and refocused on profitability. By 2023, Klarna returned to profit and saw renewed growth, aided by expanding beyond BNPL into a full shopping app with price comparison, loyalty features, and banking services (Klarna obtained a banking license in Europe in 2017). In 2025, Klarna reportedly delayed an IPO amid market volatility but ultimately went public in September 2025, raising $1.37 billion. Despite valuation fluctuations, Klarna remains the global leader in BNPL, with a strong brand among Gen Z and millennial shoppers. Its journey from a small Stockholm startup to a financial giant serving 65 million customers (2025) at one point valued at $75 billion exemplifies the rise (and resiliency) of Europe’s fintech sector.
