What The Heart Foundation does
Mission
The Heart Foundation (thf) was created to save lives from heart disease by increasing awareness, educating the public, and supporting innovative research at smidt heart institute at cedars-sinai medical center in los angeles, california. Heart disease is a leading cause of death globally. The organization provides an invaluable service not only to southern california residents both also nationally and internationally by granting a substantial portion of its annual revenue to funding research for improved methods of heart disease prevention, detection, and treatment. Furthermore, thf helps individuals advocate for, monitor, and improve their own heart health by providing high-quality, engaging, and timely educational content through its website, social media platforms (tiktok, instagram, facebook, x), youtube channel, and blog. Thf's online efforts as well as its in-person events have attracted new followers and supporters to the organization; led to the establishment of relationships with key heart health experts, organizational partners, and influencers; and built an ever-growing community committed to heart health.
As stated on its FY2025 Form 990.

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 2024 to 2025, from $9.0M to $10M (+13%).

Who funds it, year by year
2017 → 2023: the base broadened from 4 funders to 20 funders, grant income rose $43k → $641k.
3 of 38 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 9% 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 THE HEART FOUNDATION’s funders (the co-funder graph). Top 30 of 38 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 HEART FOUNDATION has a broad base — no single funder exceeds 24% 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
Largest funder’s share by year: 2017 59% · 2018 38% · 2019 38% · 2020 79% · 2021 56% · 2022 42% · 2023 44% — 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
46% of THE HEART FOUNDATION's funders are still giving 3 years after their first grant; 42% 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
93% of THE HEART FOUNDATION's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $170k arriving through sponsors registered in 2 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.
