## About

The JoMiJo Foundation is a private, tax-exempt family foundation based in San Rafael, California, founded and led by brothers Jonathan, Michael, and Joshua Frieman. The foundation's capital originates from the Frieman family and is directed entirely toward grassroots organizations working for social change. Jonathan Frieman, the foundation's president and most visible principal, is an attorney and activist known for a series of legal challenges aimed at corporate influence in American elections — a stance that directly informs the foundation's grantmaking priorities. JoMiJo's funding flows to small, community-level advocacy groups rather than large, branded nonprofits. The foundation has maintained ties to organizations including the Sierra Club's Corporate Accountability Network and the Shareholder Action Task Force, reflecting a strategy that blends traditional grantmaking with activist shareholder engagement. Geographic focus skews local to Marin County and the broader Bay Area, though some grantees operate nationally. The foundation does not deploy capital into for-profit ventures, fund commitments, or recoverable grants — it is a pure grantmaking entity. Operations are intentionally spare. The foundation lists its address as a residential property at 170 Oak Drive in San Rafael, with no known staff beyond the three founding brothers. Jonathan Frieman also serves on the advisory board of Teen Talking Circles and participates in Sustainable San Rafael and the Democratic Central Committee of Marin — affiliations that double as sourcing channels for grantee identification and political alignment. No separate investment committee or external manager structure is publicly documented. JoMiJo's structural differentiator is the tight coupling between its founder's personal legal activism and the foundation's mission. Most family foundations separate the grantmaking identity from the founder's extracurricular litigation; here, they are the same project. The foundation operates without a website or public-facing annual report, making its grantmaking activity largely opaque except through Jonathan Frieman's public court filings and political activity — a transparency posture that is itself a statement about accountability.
