Manifund is a philanthropic platform operated by Manifold for Charity, a US-registered 501(c)(3) nonprofit based in San Francisco. The platform enables donors to fund charitable projects through three core mechanisms: regranting (where expert regrantors independently allocate budgets to promising projects), impact certificates (allowing retroactive funding of completed work), and direct crowdfunding. Manifund focuses primarily on AI safety, AI governance, biosecurity, and other effective altruism cause areas, and has distributed millions of dollars in grants since launching in 2023. The organization also operates Mox, San Francisco's largest AI safety coworking and events space, and hosts Manifest, an annual festival for forecasting and prediction markets.

Theory of Change
Manifund believes that the AI safety funding ecosystem has critical gaps: traditional grantmaking is too slow, too committee-driven, and too risk-averse to fund the most promising early-stage work. By empowering individual expert regrantors with independent budgets and minimal bureaucratic overhead, Manifund enables fast, speculative grants that seed new projects and researchers before they have the track record required by larger funders. This hits-based approach, combined with full transparency (all grants, amounts, and regrantor rationales are public), creates a funding pipeline that can identify and support high-impact AI safety work at its earliest stages. Impact certificates further incentivize high-quality work by enabling retroactive funding, while the Mox coworking space builds community infrastructure that concentrates and connects AI safety researchers and organizations in San Francisco.
