Rio Vista Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation states that it does not accept unsolicited requests, so an organisation without an invitation should not send a cold proposal.
- Its grants mostly fall between $50,000 and $500,000, with a median of $100,000, and half of its 34 grants to organisations across its recent filings were $100,000 or less, so a request near that level fits its record.
- The largest grant was $2,600,000, so that band is typical rather than a ceiling.
- Climate solutions is a theme drawn from its grants, and 37% of its latest-filing grant dollars to organisations went to organisations it had also funded in earlier filings, so returning recipients form a meaningful share.
- The filing states no geographic focus; its grants have mainly gone to Missouri and California, but that describes past giving, not who may apply.

Priority Areas
Rio Vista Foundation’s grants go mainly to charitable organisations, including community organisations, universities and research bodies, arts and cultural organisations, and policy organisations. The recorded purposes include general operating support, activating community power to redesign education, health and justice systems for equity, and catalysing climate-solution ecosystems. Other projects concern climate and carbon-removal research, education, artistic programming, cultural institutions, public amenities and scientific research. This is a mixed portfolio: it combines broad support for recipients’ charitable purposes with funding for defined programmes, research and capital projects. Most grant dollars have gone to organisations in Missouri, with grants also reaching other states and outside the United States.
