What End Overdose does
Mission
Our mission is to prevent overdose deaths through free education, naloxone distribution, and community-based outreach.
As stated on its FY2024 Form 990.
Program
End Overdose operates as a single, unified program one integrated model for overdose prevention delivered through 59 distinct components organized into 11 service categories.This unified program centers on four core functions. First, training and certification: an online education platform offers five free courses (including a game-based certification for younger audiences), supplemented by in-person training delivered to bars and nightclubs, treatment centers, colleges, corporations, and public health departments, and supported by a nationwide chapter network of high school, college, city, and state chapters. Second, access and distribution: a mail-order system provides free naloxone, fentanyl test strips, and educational materials to all 50 states and U.S. territories. Third, public awareness: the organization reaches audiences through festival and mass-event activations (1,000+ events per year), mass digital campaigns, extensive media collaborations and press outreach, strategic partnerships (including TAO Group, Insomniac, and Deloitte), artist collaborations, and coordinated state and federal messaging campaigns. Fourth, equity and infrastructure: a language initiative is…

The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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 2023 to 2024, from $21k to $54k (+154%).
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: 2023 9% · 2024 1%. Grants only. Government contracts and fees sit inside program revenue.
96% of END OVERDOSE’s revenue is contributions — more reliant on donations than three-quarters of its peers (51% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 4 reported years ran a deficit.

Leadership and staff
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
2022 → 2023: the base broadened from 5 funders to 9 funders, grant income rose $39k → $70k.
5 of 17 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 71% 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 END OVERDOSE’s funders (the co-funder graph). Top 16 of 17 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
END OVERDOSE leans on a few funders — its largest provides 48% of grant income and the top three 67%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
76% 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 END OVERDOSE.
Largest funder’s share by year: 2022 49% · 2023 29% — 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.
Where its funders are
71% of END OVERDOSE's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $54k that is directly attributable, 70% of it comes from funders outside California, across 7 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $129k arriving through sponsors registered in 5 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.
