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 2020 to 2021, from $303M to $894M (+195%).
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) — 13% 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: $17M from one payer (the payer shares this organization's board, largest Carl and Marilynn Thoma Foundation). These are real filings, and they are not money Carl & Marilynn Thoma Foundation raised.

Where its funders are
Carl & Marilynn Thoma Foundation draws 100% of its grant income from funders outside Texas, across 1 state in all.
Funder states come from each funder’s own filing. $30k 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.
