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 2022 to 2023, from $137k to $198k (+44%).
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. 2 of the last 6 reported years ran a deficit.
Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 2 funders, grant income fell $5k → $1k.
3 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 35% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

the vertical line marks half of all grant income — 1 funder to its left
35% 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 BOULDER AUDUBON SOCIETY Boulder County Audubon Society.
Largest funder’s share by year: 2018 100% · 2019 67% · 2020 79% · 2021 53% · 2022 89% · 2023 94% — diversifying over time.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $40k 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.
