UX/UI Design
Interfaces that convert
and that last.
We don't design to make things look good. We design to make them work. Research, strategy, UI — in that order. Always.

Our scope.
UX Audit
We analyze what's blocking users before touching anything. User journeys, heuristics, friction points — identified and prioritized.
Wireframes & Architecture
Information first. We structure before we style. Every wireframe is a decision, not a sketch.
High-Fidelity UI
Interfaces that reflect the level of your product. Figma, components, states, mobile-first responsive.
Design System
A coherent system your teams can evolve without us. Variables, components, full documentation.
Prototype & Testing
We test before we ship. Interactive Figma prototypes, user sessions when the project calls for it.
Figma Handoff
Clean, annotated documentation, ready for dev. Zero ambiguity. Zero unanswered questions.
How it works.
Deep dive into your product, your users, your business goals. We don't start designing before we understand. (1-2 weeks)
Information architecture, user flows, wireframes validated together. Unlimited iterations. (1-2 weeks)
High-fidelity design, components, states. We iterate until it's right — not approximately right. (2-4 weeks)
Interactive prototype on the main flows. We test, we adjust. (1 week)
Annotated Figma file, design system, technical specs. Dev has nothing left to ask. (1 week)

FAQ
Do you deliver in English?
Yes. We work in both English and French. All deliverables are available in both languages. Most of our enterprise clients are English-speaking.
Do you work on existing projects?
Yes. Auditing an existing product, partial or full redesign — we adapt to where you are. No need to start from zero to do good work.
How many iteration rounds are included?
As many as needed for the result to be right. We don't count the back-and-forths — we count the results.
Do you work with our internal dev teams?
Yes, it's even preferable. We adapt the Figma handoff to your stack's conventions and can run handoff sessions with your devs.
Do you deliver mobile design too?
Always. Mobile-first is our default approach, not an add-on.
