Zennström Philanthropies was founded in 2007 by Niklas and Catherine Zennström. Its mission is to support and engage with organisations that fight for human rights, work to stop climate change and encourage entrepreneurship in order to protect our natural environment and allow those who live in it to realize their full potential.

We believe that the issues we focus on require a collaborative approach. One in which NGOs, funders, governments and individuals work together to achieve action and change. In forming partnerships and making investments, Zennström Philanthropies will seek organisations with strong leadership and that have the ability to scale their work and sustain their impact over the long-term period.

While we are always interested in learning more about the issues, the work, or the impact in our areas of focus, we are unable to accept unsolicited grant applications. Please note, any unsolicited application will not be considered.
