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: 2020 0% · 2021 0% · 2022 0% · 2023 0% · 2024 1% · 2025 1%. Grants only. Government contracts and fees sit inside program revenue.
22% of PRX Inc’s revenue is contributions — more earned-revenue than three-quarters of its peers (58% for the typical peer).
Surplus & reserves

Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 8 funders, grant income rose $11k → $814k.
12 of 18 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 35% 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: $3.0M from 7 payers (the payer shares this organization's board, largest Silicon Valley Community Foundation). These are real filings, and they are not money PRX Inc raised.
From the IRS filings of PRX 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
PRX Inc leans on a few funders — its largest provides 62% of grant income and the top three 84%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% 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 PRX Inc.
Largest funder’s share by year: 2017 99% · 2018 100% · 2019 88% · 2020 92% · 2021 44% · 2022 57% · 2023 35% — 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
67% of PRX Inc's funders are still giving 3 years after their first grant; 56% 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
PRX Inc draws 100% of its grant income from funders outside Massachusetts, across 6 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $3.2M arriving through sponsors registered in 11 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.
