Between 2021 and 2022, Klarna's valuation collapsed from $45.6 billion to $6.7 billion — a destruction of paper wealth so abrupt that it became a benchmark story for the entire fintech correction. What happened next is the more interesting part of the story: the company rebuilt, turned profitable, and filed for a US IPO at a reported valuation of $17 billion. Klarna was founded in Stockholm in 2005 by Sebastian Siemiatkowski, Niklas Adalberth, and Victor Jacobsson as a company called Kreditor — a name that described exactly what it did. The core product was a checkout button that let consumers buy now and pay later, with Klarna absorbing the credit risk and charging merchants a fee. That fee typically runs between 3% and 6% of transaction value, with the average effective rate across the global network around 3.29% per transaction. The business processed $127.9 billion in gross merchandise volume in fiscal year 2025 across 119 million active consumers. Total revenue reached $3.5 billion, a 25% year-over-year increase. CEO Sebastian Siemiatkowski, who has led the company since founding, engineered a 40% workforce reduction at the depths of the 2022 downturn — cutting headcount from roughly 6,500 to the current 3,422 employees — while simultaneously expanding AI capabilities to handle functions that previously required human operators. The London-based company holds a banking license in Europe and accepts consumer deposits, which lowers its cost of capital by an estimated 200 to 300 basis points compared to competitors who rely entirely on wholesale debt. That structural funding advantage is what separates Klarna from the majority of buy-now-pay-later companies that emerged in its wake.
Chief Executive Officer
Siemiatkowski has led Klarna since its founding, guiding the company through its 2022 valuation crash by executing a 40% workforce reduction and pivoting the business toward profitability, resulting in the company's first annual net profit of $21 million in 2024.
Chief Financial Officer
Chhabra was brought in to manage Klarna's complex capital structure during the post-crash recovery, successfully overseeing the company's transition to profitability and leading the execution of the 2025 NYSE initial public offering.
The company's risk engine, which processes over 10,000 unique data points per transaction in milliseconds, ensures that the credit losses associated with these zero-interest loans remain within acceptable thresholds, typically hovering around 2.5% to 3.0% of total gross merchandise volume, a figure that is meticulously managed through dynamic underwriting algorithms that adjust approval rates in real-time based on macroeconomic indicators and individual consumer repayment behavior. By integrating savings, budgeting, and AI-driven shopping discovery into a single application, Klarna is attempting to create the sticky, high-engagement user base necessary to compete with the incumbent tech giants that threaten to marginalize its core payments business. To counter these threats, Klarna has aggressively repositioned itself as a 'super app' for financial management, integrating price tracking, shopping rewards, and savings accounts to increase daily active engagement and reduce its reliance on the volatile e-commerce checkout funnel. The balance sheet has been fundamentally de-risked, with the company's liquidity coverage ratio exceeding 150% and its tier 1 capital ratio well above the regulatory minimums required by the Swedish Financial Supervisory Authority, ensuring that the bank can withstand a severe macroeconomic stress scenario without requiring external capital injections.
Additionally, the company's aggressive push into full-service digital banking, including savings accounts and branded credit cards, exposes it to traditional banking risks, including interest rate volatility, liquidity coverage ratio requirements, and the operational complexities of managing a diversified balance sheet in a high-rate environment. The transition from a lightly regulated technology company to a heavily supervised financial institution requires a fundamental cultural and operational shift, demanding the recruitment of seasoned banking executives, the implementation of legacy-grade risk management systems, and the navigation of a complex web of cross-border regulatory frameworks that vary significantly between the UK, the EU, and the US. Klarna's early and aggressive integration of machine learning for real-time fraud detection and credit underwriting has resulted in a proprietary risk model that processes millions of micro-transactions daily, continuously refining its approval algorithms with a depth of behavioral data that traditional banks, constrained by legacy infrastructure and batch-processing systems, simply cannot access or analyze with the same velocity. Klarna's risk engine evaluates over 10,000 unique data points per transaction, including device fingerprinting, browsing behavior, historical repayment patterns, and real-time macroeconomic indicators, allowing it to approve or decline a loan in under 200 milliseconds with a level of accuracy that minimizes fraud losses while maximizing approval rates for creditworthy consumers.
Sebastian Siemiatkowski has served as Klarna's chief executive since co-founding the company in 2005, making him one of fintech's longest-tenured founder-CEOs at roughly two decades. He steered Klarna through its 2022 near-collapse and its 2025 New York Stock Exchange debut valuing the company at over $17 billion.
In early 2024 Siemiatkowski deployed an AI customer-service assistant that handled 2.3 million chats in its first month, work he equated to about 700 full-time agents. He paired the rollout with a freeze on most hiring, publicly arguing that AI could let Klarna do more with a shrinking workforce.
After leaning heavily on AI, Siemiatkowski acknowledged in 2025 that over-automating support had hurt quality and moved to reintroduce human agents for complex issues. The reversal followed consumer-satisfaction data showing shoppers still preferred people for difficult disputes, tempering the earlier claim that AI could replace 700 agents.
Klarna became an early flagship customer of OpenAI, launching an OpenAI-powered AI assistant in February 2024 that Siemiatkowski held up as proof of the technology's cost impact. He credited the system with driving a projected profit improvement worth tens of millions of dollars through reduced support and operating expenses.
Facing the valuation crash, Siemiatkowski ordered two rounds of layoffs in 2022 totaling roughly 20% of staff, a decision he described as agonizing given many employees held now-worthless options. The cuts reset Klarna's cost base and helped deliver the company's first $21 million annual profit in 2024.
