Overview
Natixis Interépargne is a French financial services platform for retirement savings. Users had to bounce between 2 separate websites (consumer side + business side) with completely different UIs. I was embedded Product Designer as consultant, 2 years (Jan 2022 – Dec 2023).
Challenge
Users trying to simulate retirement savings were lost — inconsistent navigation, conflicting information, high drop-off before reaching savings products. But the real constraint: RGAA compliance (French accessibility standard, stricter than WCAG 2.1). Can't just redesign; must meet legal requirements.
Objective: −25% drop-off rate + 100% RGAA compliance + migrate 200+ components from legacy tools (Sketch/InVision) to a scalable system (Figma).
Approach
Unified two broken websites : Users bounced between conflicting UIs. Decision: one cohesive journey instead of separate silos.
Made accessibility the constraint : RGAA compliance from day 1, not last. Result: better design for everyone.
Made the calculator transparent : Users didn't trust black box math. Showed assumptions, step-by-step calculation. Trust went from 15% → 50%.
Migrated smartly : Audited 200 components, consolidated to 120 true components by removing redundancies.
Built governance : System docs explained "why," not just "what." Prevented regression.
