What Underwater Hypoxic Blackout Prevention Inc does
Mission
To create public awareness of shallow water blackout, including the following:1. To ban prolonged breath-holding from pools unless one is safety-trained in freediving.2. For children to be raised under the knowledge that under water breath holding is dangerous and should not be encouraged.3. To have warning labels of the dangers of prolonged breath-holding and the dangers of under-water blackouts on all spearfishing equipment, advocating safety courses in freediving.4. Ideally, to have spearfishing licensed separately from saltwater fishing, similar to a hunting license, which requires a safety course.
As stated on its FY2024 Form 990.
Program
Organization carried out its mission by publicizing the causes and prevention of shallow water blackout, both by its website and in attendance at trade shows for aquatic equipment and events.

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 2023 to 2024, from $54k to $146k (+170%).
How it's funded, over time

From the IRS filings of UNDERWATER HYPOXIC BLACKOUT PREVENTION 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

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 UNDERWATER HYPOXIC BLACKOUT PREVENTION INC.
Largest funder’s share by year: 2017 49% · 2018 73% · 2020 100% · 2021 54% · 2022 31% · 2023 42% — 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
0% of UNDERWATER HYPOXIC BLACKOUT PREVENTION INC's funders are still giving 3 years after their first grant; 47% 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
69% of UNDERWATER HYPOXIC BLACKOUT PREVENTION INC'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 $67k that is directly attributable, 75% of it comes from funders outside Georgia, across 5 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $150k arriving through sponsors registered in 8 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.
