What we do
Four disciplines, one team
UX/UI design
User research, journeys, mock-ups and interactive prototypes, design systems: interfaces that are simple to use and ready for development, including e-commerce on Magento and Hyvä.
Art direction and brand identity
Moodboards, logo, graphic charter, illustrations, motion design: a consistent visual identity, from the website to the trade-fair stand.
Web design and integration
Responsive, accessible (WCAG) and fast websites, integrated pixel-perfect on WordPress, Drupal or Magento.
Digital strategy
Positioning, benchmark, roadmap: we frame the project with you before drawing the first screen.
Our approach
What drives our work
AI as a design accelerator
AI speeds up research synthesis, screen variants and the roll-out of content and visuals. Our designers stay in charge of every choice.
Test on a real prototype
With AI, an idea becomes a working prototype on your data in a few weeks: you decide on results, not on mock-ups.
Research first
Audit, interviews, usage analysis: the best UX decisions are made before the first wireframe, AI or not.
Design systems ready for code
Documented components, Figma files and specs: what is designed is what gets built, on Magento, Symfony, React Native or Drupal.

FAQ
Your questions about the studio
What products do you design UX/UI for?
E-commerce sites (Magento, Hyvä, PrestaShop, Sylius), mobile apps, back-offices and business tools, SaaS platforms. The more technical the product, the more a joint design and development team makes the difference.
How long does a design project take?
It depends on the scope, which we define with you before starting. For Yummix, design sprints validated the full user journey in 10 days, before a single line of code.
Do you also handle development?
Yes: designers and developers work in the same agency. The designs take technical constraints into account from day one, and what is designed is what is delivered.
Can you work with our development team?
Yes. We deliver documented Figma files, component by component, that your developers or your provider can pick up with no ambiguity.
Where is the team based?
Our designers work in Lyon (France) and Hanoi (Vietnam): one team covering European and Asia-Pacific time zones.
