A practical guide to international foundation grants for global development, human rights, climate, and humanitarian work, who funds it, and how to approach them.

When most U.S.-based nonprofits think about international funding, they think about USAID. But international foundations, U.S.-based private foundations that fund global work, plus non-U.S. foundations granting internationally, are a substantial parallel funding universe that operates very differently from government funders.

For organizations working on global development, human rights, climate, humanitarian response, education, health, and many other international causes, international foundation funding is often more flexible, faster, and more relationship-driven than government money.

This guide covers how international foundation funding works and how to find and win it.

TL;DR: Quick Answers

What are international foundation grants? Foundation grants that support work in countries outside the funder’s home country.
Who offers them? U.S.-based private foundations with international programs (Gates, Hewlett, Ford, Open Society, Mott, MacArthur, and many others), plus European, Asian, and other non-U.S. foundations.
What do they fund? Global development, public health, climate and environment, human rights, education, women’s and girls’ programs, humanitarian response, and many others.
How do they differ from USAID? Generally faster, less compliance-heavy, more flexible, and more relationship-driven.

How International Foundation Funding Works

International foundation grants follow standard private and public foundation conventions: the foundation publishes priorities, applicants apply (or are invited), and decisions flow through staff and board review.

Several distinctive features matter:

Geography is explicit. International foundations focus on specific countries, regions, or themes. A funder focused on West Africa is not a fit for Southeast Asia. Match geography precisely, see funder research.

Many require U.S. fiscal sponsorship or equivalency determination for non-U.S. organizations. The IRS rules around international grantmaking add layers; many funders will only grant to U.S. 501(c)(3)s or to non-U.S. organizations that meet “equivalency determination” or “expenditure responsibility” requirements.

Local leadership is increasingly prioritized. As in USAID, international foundations have shifted toward funding local organizations directly or through local partners.

Relationships matter. International philanthropy is small relative to the work; program officers and field staff know the actors. Long-term relationships drive renewals.

Major International Foundation Funders

A non-exhaustive sample of U.S.-based foundations with significant international programs:

Bill & Melinda Gates Foundation. Global health, agriculture, development, education.
Ford Foundation. Human rights, justice, civic engagement, gender equity.
Open Society Foundations. Democracy, justice, human rights, public health.
John D. and Catherine T. MacArthur Foundation. Specific global initiatives.
William and Flora Hewlett Foundation. Global development, education, climate.
Charles Stewart Mott Foundation. Civil society, environment, and other international programs.
The Rockefeller Foundation. Health, food, climate, jobs.
Bloomberg Philanthropies. Global public health and others.
Wellspring Philanthropic Fund and other family/anonymous donors.

Non-U.S. funders to know about depending on field:

European foundations (Wellcome Trust, Robert Bosch Stiftung, King Baudouin Foundation, and many country-level funders).
Asian foundations (Tata Trusts, Nippon Foundation, and others).
Multilateral and bilateral mechanisms, while not foundations, run grant-like programs (e.g., GAVI, Global Fund, UN agencies, EU programs).

How to Find International Foundations

990 research. U.S. foundations doing international work file 990-PFs listing international grants.
Council on Foundations Global and Inside Philanthropy publications track international funders.
Peer organizations. Other international NGOs in your region or field know the active funders.
In-country networks. Local NGO associations and field-coordination bodies know who funds what.
Grant databases that include international funders.

How to Win International Foundation Grants

1. Match priorities precisely. International foundations are often issue- and geography-specific. Sending a global-health proposal to a climate funder wastes time.

2. Lead with local partnership where credible. Like USAID, foundations increasingly prioritize work with local organizations in the lead.

3. Address fiscal pathways. If you’re a U.S. organization granting to international partners, explain the fiscal arrangement, equivalency determination, expenditure responsibility, or fiscal sponsorship.

4. Show real on-the-ground knowledge. Reviewers can tell the difference between a proposal informed by lived experience in a region and a generic global pitch.

5. Plan for reporting and evaluation. International funders increasingly value rigorous monitoring, evaluation, and learning.

6. Build long-term relationships. International philanthropy rewards trust and continuity.

Where International Foundations Fit in Your Strategy

For organizations doing international work, international foundations sit alongside USAID, multilateral agencies, corporate giving with international interest, and individual major donors in your 12-month grant strategy. Foundations often provide faster, more flexible funding that complements slow but large government awards.

How Grantboost Helps

International foundations are dispersed and often invisible without dedicated research. Grantboost scans funding sources continuously and surfaces scored, mission-matched opportunities across U.S. and international funders, so global-funder prospects appear alongside USAID, corporate, and foundation prospects in one pipeline.

Drafts come back in your organization’s voice (see training AI on your past proposals), structured for each funder, whether a U.S. global-health funder, a European climate funder, or a local in-country sub-grant program.
