Creating new behavior in a conservative sector is always a challenge — especially when it comes to how people manage and move their money. Swish, the Swedish mobile payment service, set out to redefine everyday transactions with speed, simplicity, and security. Since its launch in 2012, it has grown to over 6 million users, serving individuals, companies, and organizations alike.

As a UI designer on the project, I worked on crafting a user experience that was intuitive, trustworthy, and accessible from the very beginning. In a space where trust is everything, the interface needed to feel both familiar and future-forward — balancing innovation with reliability. This wasn’t about launching a one-time solution, but designing a scalable system that could support ongoing growth and changing user needs. Because today, brands are built continuously — and the campaign era is over.
