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 2024 to 2025, from $268k to $805k (+200%).
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 7% · 2018 4% · 2019 4% · 2020 51% · 2021 16% · 2022 35% · 2023 8% · 2024 12% · 2025 4%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2017 → 2023: the base broadened from 4 funders to 6 funders, grant income fell $261k → $86k.
4 of 13 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 14% 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 TEMPESTA DI MARE INC’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
TEMPESTA DI MARE INC has a broad base — no single funder exceeds 27% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
40% 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 TEMPESTA DI MARE INC.
Largest funder’s share by year: 2017 81% · 2018 42% · 2019 31% · 2020 82% · 2021 47% · 2022 57% · 2023 44% — diversifying over time.
“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.

60% of TEMPESTA DI MARE INC's funders are still giving 3 years after their first grant; 69% 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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $220k 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.
