Guindo. Interaction Design Studio

About us

A guindo is a tree...

A guindo is a wild cherry, a very tall leafy tree that grows abundantly in the mountains of Palencia (Spain), where we usually spend summers at the family home.

...and a small design studio

Guindo is a design studio specialized in interaction design, founded by Carol Alonso and Sergi Sánchez Mancha. We adapt us on each project from the first stages of definition (research, analysis and conceptualization), information architecture / prototyping, to final design. We've been designing interfaces since late 90s, having worked in all kinds of environments and devices (desktop software, web, mobile, ATMs, tablets ...), doing collaborations with startups, consulting companies and large multinationals.

We are experts in providing design solutions in complex environments, mediating and agreeing on solutions between developers and product managers, which favor the consistency, maintenance, control and growth of digital products.

We tend to be a better fit in projects related to productivity environments, those in which optimizing tasks and improving user efficiency is key. We don't understand usability without design and viceversa. We enjoy working with care every detail.
