Case Study: Banca Sella unifies its design system for web and app banking with Belka

Banca Sella cuts app widgets from 120 variants to 17 with Belka

Banca Sella, an Italian bank with a strong focus on digital services, faced a challenge with its design workflow. The bank's design team lacked a unified standard for their component libraries, leading to inefficiencies and inconsistency between their web and mobile app designs. They partnered with the vendor Belka to optimize their process, which included a migration to Figma.

Belka implemented a solution that involved migrating all design assets to Figma and building two streamlined, multi-theme libraries for the app and website. This drastically reduced component variants; for example, app tiles were simplified from over 250 variants to just five core components. Belka also established a clear workflow method for the team to maintain the system. The result is a solid, scalable design system that allowed Banca Sella to easily adapt for new projects, significantly lightening the maintenance effort.
