Previously, she has worked as a web developer, a systems administrator, and a research assistant who studied the politics of hackers and opensource. She has facilitated safety workshops at events all over the world with social justice organisations, foundations, and small nonprofits.

Martin has been working in philanthropy and philanthropy networks long enough to realise that we all need to work together for meaningful or even systemic change – and that trust, openness and a willingness to step into discomfort are crucial elements of this path.
He has served (and is still serving) as Executive Director of Renewable Freedom Foundation, he is a member of Leap Collective, PEX and #VertrauenMachtWirkung, an alumnus of the Global Engagement Lab, and has supported EDGE Funders Alliance and other networks and initiatives inside and outside the philanthropic sector. He co-founded and co-led the Center for the Cultivation of Technology, a host organisation for open source and tech for social change projects, and is especially interested in the intersections of issues, approaches and solutions.
He holds a PhD in History and Culture from the University of Cambridge and MAs in similar fields of the humanities where imagination meets analysis.
Martin is unsure about the usefulness of bios and invites anyone who has read this far to contact him and chat about philanthropy, social change, activism, care, community health, organising – or obscure fiction and food.

Susan Treadwell, Deputy Director of the Open Society Initiative for Europe, passed away in November 2020 after a long battle with cancer. 

Susan was an Ariadne member from the network’s earliest days and served on the Advisory Board from 2017.  She was a lively presence at all of our events, both onstage and off, and could usually be found by following the sound of her infectious laugh.  Always ready with a question or thoughtful observation, she challenged us to do better and think bigger while helping to create a warm and welcoming community wherever she went.

During her 17 years at OSF, she was a champion of human rights and gender and racial justice movements across Europe and proved herself time and again to be a visionary and strategic thinker. 

With Susan’s passing, we have lost a great mind and a bright light in the human rights and philanthropic sector.
