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.
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 $203k to $503k (+148%).
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.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 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 narrowed from 2 funders to 1 funder, grant income fell $58k → $127.
5 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 95% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of Inside the Outdoors 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
Inside the Outdoors Foundation leans on a few funders — its largest provides 52% of grant income and the top three 84%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
99% 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 Inside the Outdoors Foundation.
Largest funder’s share by year: 2017 87% · 2018 60% · 2019 98% · 2020 55% · 2021 97% · 2022 98% · 2023 100% — 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.
Where its funders are
95% of Inside the Outdoors 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 $10k that is directly attributable, 100% of it comes from funders outside California, across 2 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $182k arriving through sponsors registered in 3 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.
