Read this first · the figures below need context
100% of Porter E & Helenmae Thompson Foundation’s FY2023 grant dollars went to Greater Horizons, not to grantees.
Its money now reaches organizations through that sponsor, which does not report who recommended each grant. FY2023 names 0 organizations directly, so a portfolio cannot be read from it. Everything below is therefore FY2021, the last year Porter E & Helenmae Thompson Foundation named its own grantees at scale: 16 organizations, $237k. It is dated, not current.

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 (FY17–21, $169k) land where the poverty rate runs at 9%, against an area that typically sits at 8%. 100% of those dollars go to grantees based in above-average-need neighborhoods. Most of its grants land in higher-need ZIPs.

How this is measured
20 grantees tracked through their own filings, 2017–2025.
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 2025, not grant rows in a single year, so this will not match the grant count on the cover. 20 of the 28 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.
