Klarna is an e-commerce company that provides payment services for online stores. The company has more than 1200 employees. Most of them work at the Klarna HQ in central Stockholm. We created a branded environment inspired by Klarnas backbone: algorithms and code. Our work included wayfinding in the style of hyperlinks and interior patterns inspired by Processing. We also decorated individually themed conference rooms with handwritten algorithms and binary code reflected to create optical illusions.
