The Team

Meet the in-house team

At Mistaek, we don’t just take our work seriously—we also know how to have fun. Meet my two assistants, who bring their unique energy to the studio every day:

Yoru

Yoru, Chief of Playful Inspiration

Always ready for a walk (or a brainstorming session), Yoru reminds us that creativity thrives when we take breaks and explore new perspectives (and she’s always on time in regards to this).

Yuki

Yuki, Director of Calm and Focus

A master of stillness, Yuki knows when it’s time to focus and when it’s time to add a spark of energy to every project. With a keen eye for detail, she ensures we keep our standards high.

A personalised approach, every time

At Mistaek, we believe that great design isn’t just about how things look, but how they work. It’s about crafting thoughtful solutions that drive growth and build connections. Simplicity and clarity are at the heart of everything we do, ensuring our work is as impactful as it is beautiful.

While I (André) personally lead every project, I collaborate with a trusted network of professionals to deliver the best results.

Together, we create brands that not only stand out but resonate deeply with audiences. You can learn more about our detailed process on the
