Maÿlis d'Haultfoeuille
People often remember me for the unconventional umlaut on the “y” (“trémas” → umlaut in English). A small detail that makes it memorable — and reflects the approach I bring to every project.
I’m a Paris-based digital designer with experience in regulated industries like healthtech and automotive, in creative projects with independant businesses. I bring a versatile approach that spans product, interaction, and digital experiences, combining technical expertise with strategic thinking.

Having worked in Geneva and Munich, I bring a cross-cultural perspective shaped by diverse business practices and design sensibilities. Collaboration and clear communication are central to my process, ensuring your project stays cohesive, differentiated, and strong over the long term.
With roots in both graphic design and virtual reality, I create projects that deliver visual impact and the “wow” of immersive experiences. I combine traditional brand media with hands-on work in game engines to make your communication strategy stand out.
HOW CAN MIXED-REALITY BENEFIT YOUR BUSINESS?
Mixed-reality now goes beyond games — it powers product showcases, surgical guidance tools, and educational experiences that truly engage and inform.
