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.

Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $9.8B to $10.9B (+11%).
How it's funded, over time

Who funds it, year by year
2017 → 2023: the base broadened from 17 funders to 22 funders, grant income fell $7.3M → $4.8M.
22 of 104 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 23% 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: $2.7B from 7 payers (the payer shares this organization's board, largest Mass General Brigham Incorporated & Affiliates Group Return). These are real filings, and they are not money MASS GENERAL BRIGHAM INCORPORATED raised.

MASS GENERAL BRIGHAM INCORPORATED has a broad base — no single funder exceeds 19% of grant income, and it takes 5 funders to reach half.
the vertical line marks half of all grant income — 5 funders to its left
50% 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 MASS GENERAL BRIGHAM INCORPORATED.
Largest funder’s share by year: 2017 42% · 2018 59% · 2019 68% · 2020 25% · 2021 44% · 2022 22% · 2023 31% — 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
23% of MASS GENERAL BRIGHAM INCORPORATED's funders are still giving 3 years after their first grant; 44% 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. $8.3M arriving through sponsors registered in 13 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.
