About Guillaume

Lead design and strategic design for useful, public interest services that move towards a more just society.

Designer, co-founder of Million Data_ Baby, Bloomr Impulse, and most recently joined TechforHope, a digital cooperative and commons.
100% of problems are human-made. Based on this observation, I use design to care for users and teams to get to the root of problems and solve them.

Ethics and design?

The design I advocate for and practice is ethical by nature: it respects living beings and the habitability of our planet.
I use it to serve the social and solidarity economy.
I teach at schools in the field of philosophy, ethics, and epistemology of design, integrating themes of "privacy by design", inclusion, eco-design, and digital economic and commons models.
I participate in the "inclusive design" working group of the Designers Éthiques association.

Management and team support

I greatly enjoy supporting the professional careers and development of students and designers through management focused on "caring for the person", taking into account invisible disabilities. I train and lecture on management, creativity, graphic facilitation, and organization.

Several parallel lives

I also work to protect soils, biodiversity, and natural resources through associative commitments and collective actions on the ground.
