The organization over time
Each line starts at 100 in 2024, so what you read is the shape rather than the size: 150 means half as much again as 2024, 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 2024 to 2025, from $54k to $69k (+27%).
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. 1 of the last 2 reported years ran a deficit.

Who funds it, year by year
2021 → 2023: the base broadened from 3 funders to 4 funders, grant income rose $5k → $38k.
2 of 11 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 5% 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 SALTWATER CLASSROOM’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
SALTWATER CLASSROOM leans on a few funders — its largest provides 42% of grant income and the top three 73%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
60% 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 SALTWATER CLASSROOM.
Largest funder’s share by year: 2021 95% · 2022 100% · 2023 58% — diversifying over time.
“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
63% of SALTWATER CLASSROOM's grant income comes from Maine funders.
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.
