The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 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.
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: 2020 86% · 2021 88% · 2022 87% · 2023 78% · 2024 79% · 2025 69%. Grants only. Government contracts and fees sit inside program revenue.
99% of INTERVAL HOUSE’s revenue is contributions — more reliant on donations than three-quarters of its peers (21% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 18 funders to 30 funders, grant income rose $282k → $607k.
15 of 60 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 18% 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 INTERVAL HOUSE’s funders (the co-funder graph). Top 30 of 60 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
INTERVAL HOUSE has a broad base — no single funder exceeds 20% of grant income, and it takes 5 funders to reach half.
the vertical line marks half of all grant income — 5 funders to its left
37% 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 INTERVAL HOUSE.
Largest funder’s share by year: 2017 28% · 2018 29% · 2019 31% · 2020 22% · 2021 25% · 2022 17% · 2023 13% — 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
59% of INTERVAL HOUSE's funders are still giving 3 years after their first grant; 62% 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
97% of INTERVAL HOUSE's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $773k arriving through sponsors registered in 11 statesis 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.
