What Slough Farm Foundation does
Mission
Dedicated to offering educational classes combined with hands-on training (farm internships for children, providing donations of food and other resources to the local community, food pantries and other non-profit organizations, coop programs, etc.), developing year-round greenhouse and agricultural programs, breeding heritage animals, and offering facilities to artists in residence.
As stated on its FY2024 Form 990.
Programs
The organization maintained and operated an educational farm and gathering place which teaches regenerative agriculture and hosts educational programs for local schools, as well as programming for the broader community to promote sustainable farming and the arts. In addition, the organization's working farm produced thousands of pounds of food products (produce, meat, poultry and eggs), which it donated to local schools, food pantries and other charitable organizations.

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 $46M to $74M (+61%).
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.
99% of SLOUGH FARM FOUNDATION’s revenue is contributions — more reliant on donations than three-quarters of its peers (96% for the typical peer).
Surplus & reserves

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 held at 1 funder, grant income fell $8.0M → $7.7M.
2 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 100% 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
SLOUGH FARM FOUNDATION leans on a few funders — its largest provides 100% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% 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 SLOUGH FARM FOUNDATION.
Largest funder’s share by year: 2017 100% · 2018 100% · 2019 100% · 2020 97% · 2021 100% · 2022 100% · 2023 100% — broadly stable.
“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
100% of SLOUGH FARM FOUNDATION'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 $100k that is directly attributable, 100% of it comes from funders outside Massachusetts, across 1 state.
Funder states come from each funder’s own filing. $98M arriving through sponsors registered in 2 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.
