Ideal Applicant
Medium-to-large civil society organizations, academic institutions, fiscal-sponsorship projects, or field hubs whose work advances democracy, human rights, public-interest research, or movement infrastructure and that are visible within relevant networks.
Good Fit
- • Clear programmatic alignment with democracy, human rights, civic engagement, or related policy/research priorities.
- • Existing visibility or partnerships in the Open Society/field networks (national or international).
- • Capacity to absorb multi-year or multi-million dollar core or program support.
- • Track record of convening, research, litigation, narrative change, or field-building work.
- • Fiscal sponsorship or partnership arrangements that allow participation in larger donor collaborations.
Geography
Observed grants in the latest year reached recipients across roughly 99 distinct states/regions and include many international locations, demonstrating a broad national and global footprint despite a sizable share of dollars flowing to New York.
Recipient Variety
The latest year shows 430 distinct recipients and hundreds of grants spanning universities, international NGOs, fiscally sponsored projects, and grassroots funds, indicating a very broad and diverse recipient set for the foundation's scale.
New Applicants
Direct evidence shows many new grantees in the latest year (222), but the funder signals that it funds only preselected applicants and does not maintain an open proposal intake, so unfamiliar organizations are unlikely to access funding through a public application process.
