Commerzbank
Redesigning the banking app for growth
Problem
Commerzbank, Germany’s second-largest bank, needed to overhaul its service and digital channels to stay competitive in an increasingly digital financial landscape. The challenge was to redesign the banking app with a focus on four key pillars: enhancing customer focus, providing an outstanding user experience, embracing technology-forward practices for scalability, and enabling self-service options to drive sales and user engagement.
Solution
At Neugelb, I worked primarily on the Commerzbank banking app. My role involved leading the UX & UI design efforts, ensuring alignment between user needs, business objectives, and technical limitations. I also managed the design system to ensure scalability and smooth implementation as the project grew. Additionally, I helped establish collaborative processes within the design team, which expanded from 4 to over 80 employees across various disciplines.
Design
The app’s design was centered around simplicity and ease of use, ensuring accessibility for a wide range of users, from 18+ students to busy 45+ year-old parents. We respected Commerzbank’s brand identity while also exploring the integration with its subsidiary, Comdirect. The goal was to create an intuitive, visually appealing interface that made banking easy for all.
Impact
The relaunch of the Commerzbank Banking App in 2019 was a success, reaching over 2 million users. The design system we developed laid the groundwork for a mobile app team of 13+ designers, enabling scalable contributions and a unified experience. The new app also opened up new revenue streams and significantly increased self-service engagement for the bank.
