Its FY2025 filing reports that it funds preselected organizations and did not take unsolicited requests; check the foundation's own site before ruling it out.
What it funded, over time
Every grant placed by its stated purpose and the recipient’s mission, by year, FY2017 to 2025.
Where the money goes
Grants by size, and the largest recipients.
| Recipient | Amount |
|---|---|
| UNIVERSITY OF IOWA CENTER FOR MACULAR DEGENERATION RESEARCH FUND | $6,978 |
| LUTHERAN HOUR MINISTRIES | $2,000 |
| LUTHERAN CENTER FOR THE PERFORMAING ARTS | $1,025 |

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 (FY21–21, $500) land where the poverty rate runs at 14%, against an area that typically sits at 10%. 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
17 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. 17 of the 49 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.
Where the money sits, by cause and then by grantee
