A world made better by design.

Koos uses design to improve peoples lives and transform the way teams work

What we do and how

We believe design can change the world. And to prove it, we are using design to help organizations and institutions around the world to make positive change. We’ve helped redesign financial systems to care for people in debt and medical centers to become more patient-friendly.

We aim for services that help people and planet. Because we want to be the first global design agency 100% committed to positive change.


How we define positive impact.

Who we are

We believe design can change the world, so we’ve curated a multidisciplinary team to match our ambitions: service designers and UX’ers, yes, but also data scientists, organizational designers, process facilitators, and more. With headquarters in Amsterdam, Lisboa and roots in the renowned Delft University of Technology, we enjoy our tools and methods almost as much as having fun along the way.

Who we work with

We work with organizations in any industry or field, but we prefer to collaborate with clients who share our vision for a world made better by design. From the circular economy, to financial inclusion, to accessible mobility, we’re enthusiastic about projects that improve not just the lives of customers, but also society and the planet.
