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.

03Who funds it

Who funds it, year by year

2017 → 2023: the base broadened from 6 funders to 7 funders, grant income rose $74k → $78k.

8 of 22 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 88% 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 EPILEPSY SOCIETY OF SAN DIEGO COUNTY’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.

EPILEPSY SOCIETY OF SAN DIEGO COUNTY leans on a few funders — its largest provides 57% of grant income and the top three 83%; half comes from just 1 funder.

the vertical line marks half of all grant income — 1 funder to its left

88% 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 EPILEPSY SOCIETY OF SAN DIEGO COUNTY.

first grant+1y+2y+3y+4y+5y+6y

Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.

Funder states come from each funder’s own filing. $666k arriving through sponsors registered in 7 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.
