About Yann

My obsession: creating the perfect match between YOU and your AUDIENCE by putting DESIGN at the service of your BUSINESS.

Lead designer for VESTIAIRE COLLECTIVE for 6 years, I built and led the team that created the user experience for a French platform that became a global leader in circular fashion. Driven by an entrepreneurial spirit, I then co-founded AGUA BLANCA, a committed marketplace where I was responsible for all user experience and branding product aspects. Currently Head of Design at the agency Galadrim, I lead a team of 7 designers and am directly involved in the agency's key projects (SAAS, AI, Business platforms, Apps...) from pre-sales to discovery and delivery phases.

Today, my motivation is to build, with you and your teams, and for your users, an innovative, consistent, and effective experience.

I CAN HELP YOU IF:

💡 you are looking for a partner to help you shape your ideas FROM THE DECK STAGE
📱 you want a UX/UI FOR YOUR WEBSITE/SAAS/APP that truly addresses your business challenges: co-design workshops, wireframes, AI prototypes, design systems, user testing...
🎯 you want to create or revamp your VISUAL IDENTITY
🚀 you are looking for someone to SUPPORT AND HELP YOUR design and product teams grow.

My rules for building with you are simple:
1. Listen to you, listen to you, listen to you... talk about your project.
2. Identify, analyze, and understand the keys to your business (customer journey, data...).
3. Iterate with you to build the most relevant solutions for your brand.
