the other nonprofit in this space is the Effective Institutions Project, which was linked in Zvi’s 2025 nonprofits roundup:
They report that they are advising multiple major donors, and would welcome the opportunity to advise additional major donors. I haven’t had the opportunity to review their donation advisory work, but what I have seen in other areas gives me confidence. They specialize in advising donors who have brad interests across multiple areas, and they list AI safety, global health, democracy and (peace and security).
from the same post, re: SFF and the S-Process:
SFF does not accept donations but they are interested in partnerships with people or institutions who are interested in participating as a Funder in a future S-Process round. The minimum requirement for contributing as a Funder to a round is $250k. They are particularly interested in forming partnerships with American donors to help address funding gaps in 501(c)(4)’s and other political organizations.
This is a good choice if you’re looking to go large and not looking to ultimately funnel towards relatively small funding opportunities or individuals.
