The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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 2019 to 2020, from $249k to $729k (+193%).
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.
100% of TANGO2 RESEARCH FOUNDATION INCORPORATED’s revenue is contributions — more reliant on donations than three-quarters of its peers (83% for the typical peer).

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
2020 → 2023: the base broadened from 4 funders to 8 funders, grant income fell $479k → $61k.
8 of 15 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 96% 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 TANGO2 RESEARCH FOUNDATION INCORPORATED’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
TANGO2 RESEARCH FOUNDATION INCORPORATED leans on a few funders — its largest provides 38% of grant income and the top three 83%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
99% 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 TANGO2 RESEARCH FOUNDATION INCORPORATED.
Largest funder’s share by year: 2020 97% · 2021 66% · 2022 60% · 2023 37% — 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.
How long its funders stay
50% of TANGO2 RESEARCH FOUNDATION INCORPORATED's funders are still giving 3 years after their first grant; 73% 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
96% of TANGO2 RESEARCH FOUNDATION INCORPORATED's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $72k that is directly attributable, 100% of it comes from funders outside Connecticut, across 5 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.6M 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. 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.
