What Hammer Museum Inc does
Mission
Hammer Museum
As stated on its FY2020 Form 990-EZ.
Program
The world's first museum dedicated to preserving the history of the world's first tool, the hammer.
The first program described on its most recent Form 990-EZ.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2018 to 2019, from $40k to $30k (−26%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
100% of Hammer Museum Inc’s revenue is contributions — more reliant on donations than three-quarters of its peers (78% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 4 reported years ran a deficit.
Who funds it, year by year
2017 → 2023: the base narrowed from 3 funders to 1 funder, grant income fell $48k → $16.
2 of 11 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 2% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
Hammer Museum Inc leans on a few funders — its largest provides 52% of grant income and the top three 85%; half comes from just 1 funder.

“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
0% of Hammer Museum Inc's funders are still giving 3 years after their first grant; 18% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
Hammer Museum Inc draws 91% of its grant income from funders outside Alaska, across 6 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $6k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

Hammer Museum Inc's revenue fell 71% between 2017 and 2020.
