Case Study

Banking on a better Tomorrow

Digital Banking

Tomorrow offers a sustainable mobile banking experience that enables its users to achieve a positive impact with their money. The users’ deposits are invested in sustainable projects, including renewable energies and social housing developments and for every euro a user pays with their Tomorrow card, Tomorrow protects 1 m² of rainforest from deforestation. Premium “Zero” users can even offset their carbon footprint entirely. Kitted out with the full suite of banking features, Tomorrow combines a state-of-the-art user experience with a sustainable philosophy.


To make their vision of a platform for ethical finance a reality, Tomorrow knew that at the center of their proposition they needed to offer a fully-fledged bank account. This would act as the central hub to which further value-added services around sustainable investing could then be added. This, however, was no easy feat:

  1. To offer a basic bank account and card, the German regulator demands a banking license. However, due to the immense operational effort and sunk costs required for getting a banking license, Tomorrow looked for a licensed provider that could shoulder these burdens.
  2. Further, Tomorrow needed to move quickly. The European mobile banking market was getting increasingly crowded and new features were being launched at a rapid rate. Tomorrow was in search of a partner that was on eye-level in terms of technological capability and speed.
  3. Finally, the partner of choice needed to accommodate Tomorrow’s unique brand – not just in terms of design, but also in terms of infrastructure. After all, Tomorrow wanted to offer features that allowed for investments with positive social and environmental impact.
