Join our Team

Join the OpenForests team and build together a more healthier future for all of us.



We believe that another world is possible. A world where human and nonhuman beings flourish alongside each other. A world where people are not masters of but part of what we call nature. For this to happen, we need a collective change of consciousness and to rebuild connectedness with the diversity of all life.

The ultimate goal is to give back voices to the people and give faces to their projects.

We empower people in making more biodiverse, resilient, social, and transparent forest projects.

Our story

How can we change the world?

In moments of deep friendship, we often discuss ideas of changing the world for the better. And this is the story of OpenForests and how it all started: in a tiny kitchen, late at night, we – Stefan, Patrick, and Alexander – sharing our concerns over the state of the world. Over injustices, politics, ethics, and the exploitation of nature.

Usually, the next morning one swallows down their idealism with a good cup of coffee and then back to business as usual.

But this time it was different!
