Klarna is the Swedish payments and shopping company best known for its buy-now-pay-later product. Founded in Stockholm in 2005 by Sebastian Siemiatkowski, Niklas Adalberth and Victor Jacobsson, Klarna went public on the NYSE in 2025 and operates a Lisbon product development centre that anchors its Iberian engineering and operations footprint.
Klarna entered Portugal in 2022 with the launch of its Pay-in-3 product for Portuguese consumers and the announcement of a Lisbon-based product development hub. The company sized the initial Lisbon ambition at up to 500 employees over several years, focused on engineers, product managers, designers and analysts working on Klarna’s global product surface area — not on a Portugal-specific country team.
The Lisbon hub forms part of the broader engineering footprint Klarna operates outside Sweden, alongside Berlin, Madrid and London. After a 2022 funding reset and a workforce reduction announced by CEO Sebastian Siemiatkowski, the Lisbon trajectory slowed compared with the original 500-headcount target, but remained a strategic site through Klarna’s recovery and 2025 NYSE listing. Klarna’s Pay-in-3 product is live with Portuguese merchants, embedded in checkout flows alongside Klarna’s other payment methods.
Klarna is one of the most recognisable Swedish consumer-tech brands, and its decision to anchor a product engineering hub in Lisbon validated Portugal as a senior engineering location for Nordic fintechs — not just a back-office or BPO destination. For NorthSouth HQ readers, Klarna sits inside a small but strategic cluster of Nordic-headquartered fintechs that have used Lisbon as a European technical scale-out hub. Klarna’s 2025 NYSE listing puts the Portuguese operation on a public-company reporting cycle for the first time.
