Read this first · the figures below need context
90% of Stamps Family Charitable Foundation Inc’s FY2024 grant dollars went to The Chicago Community Trust, not to grantees.
Its money now reaches organizations through that sponsor, which does not report who recommended each grant. FY2024 names 8 organizations directly, so a portfolio cannot be read from it. Everything below is therefore FY2022, the last year Stamps Family Charitable Foundation Inc named its own grantees at scale: 7 organizations, $24k. It is dated, not current.
Organizations named directly on the return
Amber years are those where most dollars went to a sponsor.
What you funded, over time
Every grant placed by its stated purpose and the recipient’s mission, by year — across FY2017–2024.
Where the money goes
Your grants by size, and where they go.
| Recipient | Amount |
|---|---|
| NYU Langone Health - J Harris Breast Cancer Community Outreach Fund | $5,000 |
| Action Against Hunger | $5,000 |
| Baptist Health South Florida Foundation Inc | $5,000 |
| The Children's Movement Of Florida | $5,000 |
| Alzheimer's Association | $1,000 |
| Miami Children's Museum | $1,000 |
| University of Miami | $1,000 |
| Bonefish And Tarpon Unlimited | $500 |
| Vermont Public | $40 |
Do your dollars go where the need is?
Each grant placed by the hardship in its grantee’s ZIP, then read against the area’s typical level.
Your human-services grants (FY17–24, $203k) land where the poverty rate runs at 16%, against an area that typically sits at 11%. 98% of those dollars go to grantees based in above-average-need neighborhoods. Most of your grants land in higher-need ZIPs.
Matched: human-services grants are those whose grantee’s IRS cause code is Human Services. Placed by people below the poverty linein the grantee’s ZIP, averaged from the tracts in that ZIP; grantee ZIP can differ from where services are delivered.
Which US states your grants reach
US grants placed by each grantee’s ZIP, which can differ from where services are actually delivered. Need from public data — U.S. Census/ACS, CDC PLACES, Eviction Lab, USDA — shown as context about the area, never attributed to your giving.
Who you back again
Which organizations you funded more than once, and which you funded a single time. Each grantee is matched to its own filings.
And the relationships you keep tend to grow: grantees you re-up on have seen median revenue of +64% since the first grant, against +56% for the ones you funded once.
32 repeat relationships — 6 still active in FY2022, 26 since wound down; 16 grantees were first funded in FY2022 (too recent to call). Read against FY2022, 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.

New vs renewed · share of each year
In FY2024, 83% of grant dollars renewed an existing relationship; $321k went to new ones.
Where new relationships form · theme of each grantee’s first grant
First-time = a grantee’s first year in your filing window; renewed = funded in an earlier year too. As a portfolio matures the renewed share naturally climbs — once funded, an org stays “renewable” — so the signal is the years that buck it (a new-grantee intake wave). The earliest year is left-censored: relationships that predate the data read as “new.” Theme is the grantee’s IRS cause.

Repeat = funded in two or more distinct years; growth and survival are read from each grantee’s own subsequent IRS filings.
The map has a center of gravity: the average direction from the rest of the sector toward the organizations the foundation funds — the shape of its giving. Scoring every nonprofit along that direction surfaces the ones that look most like the portfolio. These are the closest matchesthat aren’t grantees — a resemblance in what they say they do, not a recommendation.

For reference, the grantee most central to the portfolio’s shape is Georgia Tech Foundation Inc and the most unlike its peers is Bella Mente Quantum Racing Association. Resemblance is measured on each organization’s own IRS 990 mission text; it reflects how work is described, not its quality or impact.
For each theme you fund, this compares how the sector’s money is shifting with how your own giving is shifting.
Sector change and giving change are each shown relative to their own range, growing (right) or shrinking (left); both normalized, so inflation isn’t mistaken for growth.
Your grantees are a median of 42 years old; the field is 20. You back the established end — and your money leans older still.
The field is 18% startups (under 5 years old) — 2% of your grantees by number, and just 0% of your money.
The orgs you fund almost never close — 0.0% lost their exemption, against 12% of the field you don’t fund.
Age = years since IRS exemption (a founding proxy). “Closed” = auto-revocation for 3 years of non-filing — a floor on closure, not proof, and bigger established orgs lapse least. Association, not causation.
60 grantees tracked through their own filings, 2017–2025.
Each one resolved to its own IRS returns and tracked year by year — your grant beside their revenue from every source. Association, dated; never a causal claim.
Counted here: distinct organizations you funded across 2017–2025, not grant rows in a single year — so this will not match the grant count on the cover. 60 of the 105 grantees resolved in that span have returns of their own we could reconcile; the rest are funded organizations whose filings we could not track year by year.

The grantmakers whose grantees overlap with yours far more than size alone predicts. Each orbits closer the stronger the alignment; the arcs between them show where they also fund each other. Here it reads as a tightly interlocked camp — most of these funders back each other's grantees too.

Affinity is a Gamma-Poisson posterior co-funding rate, re-centered on the typical rate, so thin evidence shrinks toward no signal. A research starting point: overlap is association, not proof of shared intent.
Government reliance of your grantees
Every dot is one organization Stamps Family Charitable Foundation Inc funds. Left–right is the share of its income from government; up–down is the share from you. Bigger dots raise more. Filter to federal, a single department, or state — and drag the year to watch it move.
- Florida Keys Childrens Shelter Inc — 19% of income from government
- Dana-Farber Cancer Institute Inc — 7% of income from government
- University of Miami — 5% of income from government
- Barry University Inc — 1% of income from government
- Miami Children's Museum Inc Fka Miami Youth Museum — 0% of income from government
- New World Symphony Inc — 0% of income from government
- Miami Lighthouse for the Blind and Visually Impaired Inc — 0% of income from government
- Vermont Public Co — 0% of income from government
- Pan-Massachusetts Challenge Inc — 0% of income from government
- Chapman Partnership Inc — 0% of income from government
Government income is each org’s traced federal awards (USASpending — grants and contracts) plus state payments (open checkbooks) as a share of its total revenue (IRS Form 990); the self-reported government-grant line (990 line 1e) is carried for cross-check: a grantee that reports government grants we could not trace to a source is left off the chart rather than shown as receiving none. An association, not a claim that your grant caused the public funding. Coverage is precision-first — a floor, not a census; state records exist for 9 states, so a grantee outside them shows no state figure (dimmed) rather than a false zero. Federal award amounts are obligations, which can span years, so a single-year share is indicative. 990 filings lag 12–24 months.

How do I get to Stamps Family Charitable Foundation Inc?
Find your warmest path to Stamps Family Charitable Foundation Inc 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.
