What Flux Foundation does
Mission
The mission of the Flux Foundation is to engage people in large-scale public art as a catalyst for education, empowerment, and collaboration.
As stated on its FY2025 Form 990.
Program
In 2025, FLUX supported the development of large-scale artworks through the use of our workshop infrastructure and the skillset of our team. We supported one organization as a fiscal sponsor, providing technical support and consultation to enable them to bring to life a large-scale collaborative artwork.

The program described on its FY2025 Form 990. Program spending in total: $80,692.
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 2021 to 2022, from $14k to $96k (+595%).
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 Flux Foundation’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. 5 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 5 funders, grant income rose $20k → $106k.
13 of 23 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 81% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $190k from one payer (the same organization on both sides, largest Flux Foundation). These are real filings, and they are not money Flux Foundation raised.
From the IRS filings of Flux Foundation’s funders (the co-funder graph). Association, not causation. 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 concentrated its funding is
Flux Foundation has a broad base — no single funder exceeds 17% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
81% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund Flux Foundation.
Largest funder’s share by year: 2017 50% · 2018 64% · 2019 69% · 2020 43% · 2021 49% · 2022 38% · 2023 69% — growing more concentrated.
“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
40% of Flux Foundation's funders are still giving 3 years after their first grant; 30% 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
81% of Flux Foundation's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $156k that is directly attributable, 61% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $658k arriving through sponsors registered in 11 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.
Against its field
Flux Foundation's revenue fell 59% between 2017 and 2025.
