We help you define, optimize and design the interface for your product

About us

We are Carol Alonso, Sergio Sanchez & Marià Codina, a small team of interaction designers based in Barcelona (Spain) with a wide experience in international projects.

We can help you better define and design your product, from conceptual prototypes to visual design, applying user-centered design methodology and our experience (we've been designing graphical user interfaces since 1998).

We feel lucky to work on something that excites us.
