The Tt Foundation
Its FY2024 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 2024.
Where the money goes
Grants by size, and the largest recipients.
| Recipient | Amount |
|---|---|
| DIRECT RELIEF | $2,500 |
| MEDICAL AID FOR PALESTINIANS | $2,500 |
| WING LUKE MUSEUM | $2,500 |
| BALLARD HIGH SCHOOL PERFORMING ARTS | $2,500 |
| UNIVERSITY OF WASHINGTON | $700 |
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 (FY20–23, $5k) land where the poverty rate runs at 8%, against an area that typically sits at 10%. 0% of those dollars go to grantees based in above-average-need neighborhoods. Its grants skew toward lower-need ZIPs.

How this is measured
33 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. 33 of the 60 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.
