/ Overview
A vibrant brand, payment card and banking app for a fintech startup made for creative freelancers.
/01
The Challenge
Banking for freelancers is usually grey and serious. Prism wanted to feel like a creative tool, without losing the trust people need to hand over their money.
/02
Our Solution
We built a faceted, holographic identity that carries from the payment card to the app icon. The app and website use bold colour for moments of delight and stay calm wherever money is involved.
