Who we are
Klarna’s mission is to free people from all the meaningless time spent managing money and purchases, so they can do more of what they love. Every day at Klarna we help consumers, merchants, and partners to explore just how smoooth the modern purchase experience can be. Our position at the crossroads of payments, consumer financing, ecommerce and banking means we are uniquely positioned to do this. There is no label for what we do.
Klarna was born in Stockholm in 2005 and today has 2000 employees working across Europe and the US. We currently serve 60 million consumers, work together with 90,000 merchants and process more than a million payment transactions a day. We are growing at 40% year on year and our investors include Visa, Atomico, Sequoia Capital, Permira and Bestseller group/ Anders Holsch Povlsen. We have strong partnerships with some of the world’s leading brands, such as ASOS, IKEA, Adidas, Zara, Lufthansa and Spotify.

Ever wondered why banking is so customer unfriendly? The UX is a nightmare, modern features with quick logins and integrations seem non-existent. Feature rollouts take months and that’s just not smoooth.
At Klarna we aim to fix that. We want to create a banking offer that is both a pleasure to use as a consumer and one that you as a developer can use for your Fintech startup. Starting a new bank? Use our platform. Want to launch your own credit card? Use our platform. We do all the heavy lifting for you, providing a secure and compliant set of APIs which allow developers to focus on adding value through building their own financial products and services
By being based on a modern architecture in the cloud, utilizing tools such as Erlang, Haskell, Clojure and Scala combined with a serverless architecture -- we will deliver on that expectation.
We're expanding several of our financial platform engineering teams; scaling up the backend of Klarna Checkout and ensuring our highly available purchase accepting system can handle ever increasing traffic volumes. We're always adding functionality into our payment processing systems and building a modern banking platform.
