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 2019 to 2020, from $556k to $1.1M (+101%).
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: 2018 22% · 2019 1% · 2020 4% · 2021 13% · 2022 13% · 2023 18% · 2024 20%. Grants only. Government contracts and fees sit inside program revenue.
95% of WEST MARIN COMMUNITY SERVICES’s revenue is contributions — more donation-reliant than the typical peer (82% for the typical peer).

The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 5 funders to 15 funders, grant income rose $72k → $594k.
9 of 29 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 39% 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 WEST MARIN COMMUNITY SERVICES’s funders (the co-funder graph). Top 28 of 29 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
WEST MARIN COMMUNITY SERVICES leans on a few funders — its largest provides 36% of grant income and the top three 79%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
81% 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 WEST MARIN COMMUNITY SERVICES.
Largest funder’s share by year: 2017 69% · 2018 72% · 2019 52% · 2020 55% · 2021 41% · 2022 62% · 2023 39% — 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
50% of WEST MARIN COMMUNITY SERVICES's funders are still giving 3 years after their first grant; 52% 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
WEST MARIN COMMUNITY SERVICES draws 58% of its grant income from funders outside California, across 4 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.7M arriving through sponsors registered in 6 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.
Against its field
WEST MARIN COMMUNITY SERVICES holds deeper cash reserves than three-quarters of the 1,504 philanthropy nonprofits its size.
