ASTS Foundation

What ASTS Foundation does

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 2021 to 2022, from $24M to $20M (−16%).

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.

Surplus & reserves

Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 8 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.

The chief executive listed changed between the FY2023 and FY2024 filings.

Who funds it, year by year

2017 → 2023: the base narrowed from 3 funders to 2 funders, grant income fell $139k → $133k.

3 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 69% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

Left out of every figure on this page: $288k from one payer (the payer shares this organization's board, largest American Society of Transplant Surgeons). These are real filings, and they are not money ASTS Foundation raised.

From the IRS filings of ASTS Foundation’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

ASTS Foundation leans on a few funders — its largest provides 55% of grant income and the top three 98%; half comes from just 1 funder.

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 ASTS Foundation.

Largest funder’s share by year: 2017 89% · 2018 100% · 2019 92% · 2020 100% · 2021 77% · 2022 100% · 2023 94% — 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

69% of ASTS 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 $153k that is directly attributable, 100% of it comes from funders outside Virginia, across 1 state.

Funder states come from each funder’s own filing. $340k 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.
