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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $893k to $427k (−52%).
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.
Government-grant reliance: 2017 18% · 2018 18% · 2019 18% · 2020 22% · 2021 37% · 2022 22% · 2023 15% · 2024 4% · 2025 11%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $1k → $40k.
2 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 4% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $10k 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. 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.
