What Walden Foundation Inc does
Mission
Walden center and school is an independent , k-6 school where drama, music and art sit alongside traditional academic subjects as our core curriculum. Walden's philosophy of education incorporates the following principles (sch o):integrating arts and academics-artistic expression is an essential element of every child's education. Encouraging the whole child- children learn best when their academic, emotional, physical, and social needs are addressed concurrently. Seeing children as individuals- in designing and implementing curricula, we take an individualized approach in order to meet each child where he or she is developmentally. Teaching as a collective- the teachers run the school, which provides them with autonomy and flexibility in the classroom and direct participation in school-wide decision making. Our approach to learning encourages creativity, collaboration, and critical thinking as means to help children develop a lifelong love of learning, a strong sense of commmunity.
As stated on its FY2025 Form 990.

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 $4.2M to $4.4M (+5%).
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 8% · 2021 12% · 2022 11%. Grants only. Government contracts and fees sit inside program revenue.
1% of WALDEN FOUNDATION INC’s revenue is contributions — more earned-revenue than three-quarters of its peers (48% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base narrowed from 2 funders to 1 funder, grant income fell $10k → $174.
3 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 41% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
WALDEN FOUNDATION INC leans on a few funders — its largest provides 55% of grant income and the top three 94%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
41% 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 WALDEN FOUNDATION INC.
Largest funder’s share by year: 2017 75% · 2018 77% · 2019 100% · 2020 100% · 2021 68% · 2022 95% · 2023 100% — growing more concentrated.
“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.
Where its funders are
WALDEN FOUNDATION INC draws 93% of its grant income from funders outside California, across 2 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $26k 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.
