What Marin Promise Partnership does
Mission
Marin Promise Partnership is a county-wide collaboration focused on closing educational opportunity gaps in marin. We do this by aligning efforts across schools, nonprofits, and civic leaders, especially in high-need communities like the canal, marin city, novato, and west marin. By tracking equity data and supporting community-driven solutions, we help transform systems and ensure every child can thrive, no matter their race, background, or zip code.
As stated on its FY2025 Form 990.
Programs
Cross-functional partner support: Marin Promise Partnership's "cross-functional partner support" includes 3 critical components of its backbone identity, including its data, communications, and partner engagement functions. In its data function, Marin Promise Partnership's backbone team shares data (numbers and narratives) to coordinate services, set collective goals, hold each other accountable to results, and to learn and lead with integrity. Within its communications function, the backbone team works to foster a shared identity and a common agenda across the partnership by raising up mutually reinforcing activities and synergistic efforts that lead toward education equity. Lastly, within the partner engagement function, the backbone team regularly convenes a leadership team and board to ensure the partnership is, respectively, enacting its collaborative programmatic agenda and stewarding its resources for long-term sustainability.

The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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 $1.8M to $2.9M (+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: 2021 9% · 2022 5% · 2023 4% · 2024 4% · 2025 7%. Grants only. Government contracts and fees sit inside program revenue.
88% of MARIN PROMISE PARTNERSHIP’s revenue is contributions — more donation-reliant than the typical peer (48% for the typical peer).

Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 10 funders, grant income rose $5k → $1.3M.
8 of 23 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 51% 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 MARIN PROMISE PARTNERSHIP’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
MARIN PROMISE PARTNERSHIP leans on a few funders — its largest provides 36% of grant income and the top three 74%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
96% 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 MARIN PROMISE PARTNERSHIP.
Largest funder’s share by year: 2018 100% · 2020 50% · 2021 72% · 2022 50% · 2023 41% — 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
42% of MARIN PROMISE PARTNERSHIP's funders are still giving 2 years after their first grant; 61% 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
51% of MARIN PROMISE PARTNERSHIP'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 $3.7M that is directly attributable, 56% of it comes from funders outside California, across 6 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $3.8M arriving through sponsors registered in 7 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
MARIN PROMISE PARTNERSHIP's revenue fell 54% between 2021 and 2025.
