Programs
School Based Mentoring - Sonoma Valley Mentoring Alliance maintained eight mentoring centers located on public school campuses in the Sonoma Valley Unified School District (4 elementary schools, 2 middle schools and 1 high school). These centers provide oversight and assistance to our one-on-one mentoring matches between an adult mentor and a youth mentee (grades K-12) during the nine months of the school year. In the year ended June 30, 2025, these centers provided services to approximately 300 mentor-mentee matches.

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 2024 to 2025, from $898k to $1.8M (+96%).
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 6% · 2022 7% · 2025 5%. Grants only. Government contracts and fees sit inside program revenue.
96% of Sonoma Valley Mentoring Alliance’s revenue is contributions — more reliant on donations than three-quarters of its peers (48% for the typical peer).
Surplus & reserves

14 of 47 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 43% 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 Sonoma Valley Mentoring Alliance’s funders (the co-funder graph). Top 30 of 47 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
Sonoma Valley Mentoring Alliance has a broad base — no single funder exceeds 18% 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
45% 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 Sonoma Valley Mentoring Alliance.
Largest funder’s share by year: 2017 24% · 2018 29% · 2019 24% · 2020 18% · 2021 19% · 2022 25% · 2023 20% — 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
61% of Sonoma Valley Mentoring Alliance's funders are still giving 3 years after their first grant; 66% 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
72% of Sonoma Valley Mentoring Alliance's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.5M arriving through sponsors registered in 10 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.
