What Anti Entropy does
Mission
Provided operations consulting and support to various high-impact, not-for-profit organizations.
As stated on its FY2025 Form 990.
Programs
On its FY2025 return the organization reported a significant change in how it conducts a program.
Anti Entropy significantly scaled up its fiscal sponsorship service to nascent nonprofit projects that align with the mission of Anti Entropy, with several new projects added during the year. In addition, Anti Entropy provided less operations consulting and system implementation services to outside organizations.
Its own explanation, from Schedule O of that return (Part III, line 3).

The organization over time
Each line starts at 100 in 2022, so what you read is the shape rather than the size: 150 means half as much again as 2022, 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 $232k to $2.3M (+889%).
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.
100% of ANTI ENTROPY’s revenue is contributions — more reliant on donations than three-quarters of its peers (61% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 4 reported years ran a deficit.

Leadership and staff
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
Grant support over time, funder by funder — shade shows the grant size each year.
2 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 49% 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 ANTI ENTROPY’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
ANTI ENTROPY leans on a few funders — its largest provides 51% 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 ANTI ENTROPY.
“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
ANTI ENTROPY draws 100% of its grant income from funders outside Texas, across 1 state in all.
Funder states come from each funder’s own filing. $216k 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.
Against its field
ANTI ENTROPY runs a healthier operating margin than three-quarters of the 2,127 community improvement nonprofits its size.
