Key takeaways

Archstone Foundation funds work to improve health and social care for older adults in California, so fit depends on serving that population within California.
It operates by invitation only and does not accept unsolicited requests, so a speculative approach or letter of inquiry will not work; it is best to wait to be invited rather than trying to pitch directly.
Most grants are modest: half of its 187 grants across its last three filings were $25,000 or less, and its overall grant range sits between $50,000 and $100,000, so a request in that band is realistic, though its filings also show one award of $259,000, well above the usual range.
The foundation's giving is strongly relationship-led: in its latest filing, 78% of its grant dollars went to organisations it had already funded in prior filings, so returning partners dominate and new applicants are likely to find it highly competitive.
It does not fund capital campaigns, individuals, biomedical research, or political campaigns, voter registration drives or lobbying for specific legislation, and it will not fund organisations that discriminate on the basis of age, disability, race, colour, religion, gender, gender identity and expression, national origin, citizenship status, sexual orientation, or veteran status.

What they fund

Priority Areas

Archstone Foundation seeks to improve health and social care for older adults in California, especially those facing barriers to quality care. It grants to eligible California 501(c)(3) nonprofits, national organisations with a California footprint, and California state and local government entities. Its two aims are mobilising communities and amplifying older adults’ voices, and building the adaptability of organisations serving older adults. Under the first, it prioritises narrative change, grassroots organising and digital inclusion. Under the second, it supports organisational infrastructure, coalition building and flexible funding for small community-based organisations. Its approach is to partner with communities and strengthen older adults’ leadership, advocacy and civic engagement, while helping trusted organisations adapt and build networks.
