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 2019 to 2020, from $4.5M to $6.0M (+33%).
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: 2021 11% · 2022 11% · 2023 19% · 2024 9% · 2025 2%. Grants only. Government contracts and fees sit inside program revenue.
48% of HART SQUARE FOUNDATION INC’s revenue is contributions — about as donation-reliant as the typical peer (87% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

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
2017 → 2023: the base broadened from 3 funders to 21 funders, grant income rose $78k → $267k.
9 of 35 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 24% 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 HART SQUARE FOUNDATION INC’s funders (the co-funder graph). Top 30 of 35 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
HART SQUARE FOUNDATION INC has a broad base — no single funder exceeds 16% 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
26% 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 HART SQUARE FOUNDATION INC.
Largest funder’s share by year: 2017 64% · 2018 76% · 2019 100% · 2020 37% · 2021 37% · 2022 27% · 2023 21% — 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
30% of HART SQUARE FOUNDATION INC's funders are still giving 3 years after their first grant; 63% 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
88% of HART SQUARE FOUNDATION INC's grant income comes from North Carolina funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $299k 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.
Against its field
HART SQUARE FOUNDATION INC's funding base is broadening — from 3 funders to 21 as grant income climbed.
