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.
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 34% · 2018 41% · 2019 38% · 2020 50% · 2021 55% · 2022 58% · 2023 64% · 2024 54%. Grants only. Government contracts and fees sit inside program revenue.
92% of THE MASS MENTORING PARTNERSHIP INC’s revenue is contributions — more donation-reliant than the typical peer (61% for the typical peer).

From the IRS filings of THE MASS MENTORING PARTNERSHIP INC’s funders (the co-funder graph). Top 30 of 42 funders by total. 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
THE MASS MENTORING PARTNERSHIP INC has a broad base — no single funder exceeds 25% 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
69% 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 THE MASS MENTORING PARTNERSHIP INC.
Largest funder’s share by year: 2017 70% · 2018 35% · 2019 36% · 2020 27% · 2021 33% · 2022 25% · 2023 28% — 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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.3M arriving through sponsors registered in 6 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.
