What Manifund does
Manifund (legally “Manifold for Charity”, EIN 88-3668801) is a U.S. 501(c)(3) public charity that operates a software-mediated, transparency-first grantmaking and regranting platform for charitable projects, with an emphasis on AI safety and effective-altruism-aligned cause areas. Its core product model lets donors (and, in some rounds, “investors”) fund projects through structured mechanisms—most notably “regranting” (delegating budgets to independent expert regrantors) and “impact certificates” / impact-market-style prize rounds—while also making proposals, evaluations, and finances largely public on the platform.
Strategically, Manifund positions itself as infrastructure for faster and more specialized grant decisions: rather than running grantmaking only through a centralized team, it scales evaluation and allocation by recruiting expert individuals as regrantors and by running prize-style rounds where funders can participate in allocating funds to projects. The organization also publishes operational research and tooling in adjacent “funding intelligence” areas, such as Trace (a database intended to make tracking of AI-safety funding more comprehensive) and ongoing newsletter-style reporting about funders and funding dynamics.
