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.
Balance sheet
Total assets at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $9k to $0 (−100%).
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 2 reported years ran a deficit.
Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 3 funders, grant income rose $7k → $30k.
From the IRS filings of STARS’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
STARS leans on a few funders — its largest provides 75% of grant income and the top three 90%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
Largest funder’s share by year: 2017 62% · 2018 80% · 2019 82% · 2020 93% · 2021 91% · 2022 46% · 2023 83% — 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.
How long its funders stay
43% of STARS's funders are still giving 3 years after their first grant; 45% give in more than one year at all.
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.
Where its funders are
99% of STARS's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. 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.

These figures are read directly from IRS Form 990 / 990-PF e-file XML: this organization’s own return for FY2023 (financials across 2022–2023), and the filings of 11 funders that report grants to it. “On record” means captured in the filings we have parsed — a funder that does not e-file, or whose grant detail is not itemized, will not appear. Filings run roughly 12–24 months behind. Trends on this page end at FY2023, the last fiscal year that has finished arriving; later years are shown and marked, and move no figure.
