Yousign Design System

About the Project

As Yousign scaled its product offerings and team, the need for a unified design system became critical. The project aimed to create a comprehensive design system that would streamline development, ensure consistency, and improve the overall user experience across all Yousign products.

Yousign Design System overview

The Challenge

We faced several key challenges in building the design system:

  • Multiple product teams with different tech stacks
  • Legacy components and inconsistent styling
  • Need for accessibility compliance
  • Complex signature flow requirements
  • International market considerations
Legacy component variationsDesign inconsistencies

Research & Discovery

Our research phase included extensive analysis of existing components, user needs, and development workflows. We conducted:

  • Comprehensive component audit across all products
  • Interviews with designers, developers, and product managers
  • Analysis of development bottlenecks and pain points
  • Review of accessibility requirements and compliance needs
