Castner Family Foundation
Its FY2026 filing reports that it funds preselected organizations and did not take unsolicited requests; check the foundation's own site before ruling it out.
Read this first · the figures below need context
100% of Castner Family Foundation’s FY2026 grant dollars went to Renaissance Charitable Foundation Inc, not to grantees.
Its money now reaches organizations through that sponsor, which does not report who recommended each grant. FY2026 names 0 organizations directly, so a portfolio cannot be read from it. Everything below is therefore FY2025, the last year Castner Family Foundation named its own grantees at scale: 11 organizations, $7k. It is dated, not current.
Organizations named directly on the return
Amber years are those where most dollars went to a sponsor.

Does the money reach high-need areas?
Each grant placed by the hardship in its grantee’s ZIP, against the area’s typical level.
Its human-services grants (FY23–23, $100) land where the poverty rate runs at 4%, against an area that typically sits at 11%. 0% of those dollars go to grantees based in above-average-need neighborhoods. Its grants skew toward lower-need ZIPs.

Who it funds again
Organizations funded in more than one year, against those funded once.
Grantees it renews have grown median revenue +82% since the first grant, against +11% for those funded once.
7 repeat relationships: 2 still active in FY2025, 5 since wound down; 11 grantees were first funded in FY2025 (too recent to call). Read against FY2025, the last year this funder named its own grantees directly; its giving has since run through a sponsor, which reports no donor behind each grant.

17 grantees tracked through their own filings, 2017–2026.
Each grant beside the grantee’s revenue from every source, year by year.
How this is measured
Counted here: distinct organizations funded across 2017 to 2026, not grant rows in a single year, so this will not match the grant count on the cover. 17 of the 44 grantees resolved in that span have returns of their own we could reconcile.
Each grantee is resolved to its own IRS returns. Association, dated; never a causal claim.

Co-funders
Grantmakers whose grantees overlap with this funder’s far more than size alone predicts. Closer means stronger alignment; arcs show where they also fund each other. Here they form a tightly interlocked group: most of these funders back each other's grantees too.
