What Lets Go Compost does
Mission
Let's go compost is a 501(c)(3) non-profit dedicated to making composting free and accessible throughout the united states. Our mission is to revolutionize waste management, reduce landfill waste, and combat harmful greenhouse gas emissions.
As stated on its FY2025 Form 990-EZ.
Program
Let's Go Compost provides standardized composting kits paired with standards-aligned curriculum to educational institutions nationwide. The program integrates soil science, waste reduction, climate literacy, and circular economy principles into daily instruction through hands-on composting systems. Educators and program leaders receive materials, lesson plans, signage, and implementation guidance. During 2025, the organization expanded beyond K-12 schools to serve libraries, museums, Girl Scout troops, and other community educational groups. Participants receive composting kits, worms, and bins, along with access to free downloadable curriculum.

The organization over time
Each line starts at 100 in 2024, so what you read is the shape rather than the size: 150 means half as much again as 2024, 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 $37k to $65k (+77%).
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.
78% of LETS GO COMPOST’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 2 reported years ran a deficit.

Who funds it, year by year
Grant support over time, funder by funder — shade shows the grant size each year.
1 of 8 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 2% 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 LETS GO COMPOST’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
LETS GO COMPOST leans on a few funders — its largest provides 52% of grant income and the top three 78%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
“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
LETS GO COMPOST draws 100% of its grant income from funders outside Arizona, across 7 states in all.
Funder states come from each funder’s own filing. $2k arriving through sponsors registered in 1 state 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.
