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 2022 to 2023, from $81M to $92M (+14%).
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: 2021 2% · 2022 6% · 2023 11% · 2025 0%. Grants only. Government contracts and fees sit inside program revenue.
4% of LANDMARK SCHOOL INC’s revenue is contributions — more earned-revenue than three-quarters of its peers (23% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 19 funders to 25 funders, grant income rose $445k → $741k.
16 of 63 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 79% 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 LANDMARK SCHOOL INC’s funders (the co-funder graph). Top 30 of 63 funders by total. 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
LANDMARK SCHOOL INC leans on a few funders — its largest provides 43% of grant income and the top three 66%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
79% 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 LANDMARK SCHOOL INC.
Largest funder’s share by year: 2017 31% · 2018 50% · 2019 85% · 2020 38% · 2021 27% · 2022 53% · 2023 26% — 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
46% of LANDMARK SCHOOL INC's funders are still giving 3 years after their first grant; 63% 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
79% of LANDMARK SCHOOL INC'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 $2.5M that is directly attributable, 80% of it comes from funders outside Massachusetts, across 17 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $9.3M 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.
