We are radius.


We use all our skills and experience to make a good life possible for everyone.
We work with progressive civil society organizations, institutions and social movements and with all those who share our values: social justice, ecological sustainability, solidarity and the vision of a world in which a good life is possible for all.
Whether you are a large organization or a small grassroots group, we can help you develop well thought-out strategies, plan effective campaigns and tell powerful stories.

Our team

Manuel Grebenjak
he/she
Strategist and networker with an eye for the big picture. Manuel has more ideas than there are hours in a day and still always keeps an overview. OK, most of the time anyway.

Sarah Tanner
she/he
A campaigner with a heart and a project manager with a brain. With Sarah, no posting goes astray and no deadline is forgotten. At least not by us.

Stefan Holly
he/she
The financial expert in the team. Without Stefan, our coffers would be empty, as would our private accounts and fridges.

Veronika Winter
she/he
Climate activist and education expert. The soon-to-be doctor has many years of experience at university and on the streets. Not just on Fridays.

Joel Foramitti
he/she
He has a solution for everything: Joel develops digital tools for every possible application. He can usually explain them too.
Other club members
Our core team is part of a larger whole: Several association and founding members have been involved from the very beginning and have made a significant contribution to radius. They are still involved in the association today to varying degrees and their impulses have had a lasting impact on our development.
