Mize 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 Mize Family Foundation’s FY2026 grant dollars went to Jefferson Community Foundation, 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 FY2023, the last year Mize Family Foundation named its own grantees at scale: 7 organizations, $250k. It is dated, not current.
Organizations named directly on the return
Amber years are those where most dollars went to a sponsor.
What it funded, over time
Every grant placed by its stated purpose and the recipient’s mission, by year, FY2017 to 2024.

Does the money reach high-need areas?
Each grant placed by the hardship in its grantee’s ZIP, against the area’s typical level.
US giving: 87% of grant dollars ($1.9M). The need read here covers only this US portion; the 13% that went abroad ($270k) is mapped below.
Its human-services grants (FY17–23, $80k) land where the poverty rate runs at 9%, against an area that typically sits at 9%. 44% of those dollars go to grantees based in above-average-need neighborhoods. Its grants spread fairly evenly across need levels.
How this is measured
Which US states its grants reach
Beyond the US: 13% of all-years giving ($270k)
6 countries, by the recipient’s country on the filing.
How this is measured
Where the work is directed
The same grants placed two ways: where each recipient sits, and where its stated purpose sends the money.
About 7% of Mize Family Foundation’s grant dollars are earmarked for a different county than the recipient’s own address.
How this is measured
Who it funds again
Organizations funded in more than one year, against those funded once.
25 repeat relationships: 13 still active in FY2023, 12 since wound down; 3 grantees were first funded in FY2023 (too recent to call). Read against FY2023, 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.

How this is measured
29 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. 29 of the 48 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.

How do I get to Mize Family Foundation?
Find your warmest path to Mize Family Foundation through trustees and officers whose names appear on both boards. Search for your organization and Plinth traces the shortest route it can evidence.
Each link is a name appearing on two organizations’ public IRS 990 filings, matched on that name and, where the filings support it, on location. A same-state match has geographic support, which is a second matching feature rather than confirmation that the two are one person; a cross-state one is the likeliest to be two people who share a name. Every hop shows its tier, low-confidence and distant paths are held back rather than guessed, and it is worth confirming the person before you use the introduction.
