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 2023 to 2024, from $23M to $37M (+59%).
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 90% · 2018 90% · 2019 85% · 2020 80% · 2021 90% · 2022 93% · 2023 94% · 2024 92% · 2025 91%. Grants only. Government contracts and fees sit inside program revenue.
92% of SAGE INTERNATIONAL SCHOOL OF BOISE’s revenue is contributions — more donation-reliant than the typical peer (23% for the typical peer).

Who funds it, year by year

3 of 9 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.
From the IRS filings of SAGE INTERNATIONAL SCHOOL OF BOISE’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
SAGE INTERNATIONAL SCHOOL OF BOISE leans on a few funders — its largest provides 64% of grant income and the top three 99%; 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 SAGE INTERNATIONAL SCHOOL OF BOISE.
Largest funder’s share by year: 2018 100% · 2019 100% · 2020 83% · 2021 69% · 2022 36% · 2023 50% — 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
67% of SAGE INTERNATIONAL SCHOOL OF BOISE's funders are still giving 3 years after their first grant; 56% 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
SAGE INTERNATIONAL SCHOOL OF BOISE draws 99% of its grant income from funders outside Idaho, across 3 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $423k 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.
