Ariadne is a European peer-to-peer network of more than 600 funders and philanthropists who support social change and human rights

We envision a future in which philanthropy is at the service of the movements, communities, and individuals it supports, bringing its resources to equitable partnerships.

In our network, we create spaces for joint reflection and learnings, help build trusted relationships among funders, and foster creative collaboration in the philanthropy sector to help build this future.

  • What we do

    Ariadne enables funders to achieve more together than they can individually, by providing access to community-created tools and a supportive network of colleagues.
