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 2024 to 2025, from $559k to $851k (+52%).
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.
Government-grant reliance: 2017 3% · 2018 4% · 2019 2% · 2021 1% · 2022 13% · 2023 9% · 2024 2% · 2025 4%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 5 funders to 11 funders, grant income rose $9k → $84k.
7 of 30 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 65% 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 Music Mountain Incorporated’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
Music Mountain Incorporated leans on a few funders — its largest provides 47% of grant income and the top three 69%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
74% 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 Music Mountain Incorporated.
Largest funder’s share by year: 2017 55% · 2018 40% · 2019 26% · 2020 89% · 2021 51% · 2022 27% · 2023 27% — 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.
How long its funders stay
22% of Music Mountain Incorporated's funders are still giving 3 years after their first grant; 60% 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
65% of Music Mountain Incorporated'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 $228k that is directly attributable, 59% of it comes from funders outside Connecticut, across 9 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $430k arriving through sponsors registered in 4 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.
Government funding Music Mountain Incorporated receives
