What Knox Blocks Foundation does
Mission
Our mission is to provide and support resources, research and education to families in need and to child loss families.
As stated on its FY2025 Form 990.
Programs
Knox blocks is partnered with owlet baby care providing a health and wellness monitor to families across the country. As the infant wears the owlet while they sleep it provides parents with peace of mind. Knox blocks has provided over 8,000 monitors to families in all 50 states. Today there is still no cure or full understanding of sids (sudden infant death syndrome). We are passionate about finding the end to sids. We work closely with robert's project out of boston children's hospital to help provide funding for their research. We believe this incredible team of world's best researchers, doctors and scientists will one day find the answers and the ending to sids.
$162,810 spentof which $143,095 as grants$21,821 earned by the program49% of program spendingKnowing how important it is to have eyes on your infant at all times we also know this isn't possible. Especially in a daycare environment. Because of this we have launched the green glow project, providing all licensed and registered daycare centers and in-home providers with owlets for all infants in their care in the state of iowa. We currently have owlets placed in half the counties in iowa and 600 infants are being monitoredwhile they sleep each day.
Every year wehold our annual nursery of hope. We provide infant loss families with a tree to plant in honor of their little one that left this world too soon. We have created a little forest in memory of these angels at hickory hills park in iowa. We provide this special day and place at no cost to the families. To date we have over 100 trees planted in honor of these babies.
$5,207 spent$1,000 earned by the program2% of program spendingIn partnership with many other organizations and parent-led nonprofits from around the world, Knox Blocks Foundation plans to raise money during the month of october in honor of sids awareness month to help dr. Harrington continue her groundbreaking research. Last year, dr. Harrington made a breakthrough in her research. Her lab identified that the enzyme butyrylcholinesterase was significantly lower in babies who died of sids. We need your help to fund the next phase of her teams research which will focus on identifying more biomarkers that will enable us to know which babies are indeed at a higher risk of sids, opening new avenues for research into specific interventions. The next phase of her research could change the course of the more than 3,000 families who are impacted by sids each year.

The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $138k to $384k (+178%).
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.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 8 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
2017 → 2023: the base broadened from 1 funder to 2 funders, grant income fell $1k → $647.
2 of 9 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 27% 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 KNOX BLOCKS FOUNDATION’s funders (the co-funder graph). Top 8 of 9 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
KNOX BLOCKS FOUNDATION leans on a few funders — its largest provides 62% of grant income and the top three 93%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
27% 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 KNOX BLOCKS FOUNDATION.
Largest funder’s share by year: 2017 100% · 2019 91% · 2020 91% · 2021 97% · 2022 58% · 2023 61% — 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
29% of KNOX BLOCKS FOUNDATION's funders are still giving 3 years after their first grant; 22% 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
KNOX BLOCKS FOUNDATION draws 92% of its grant income from funders outside Iowa, across 4 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $22k 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.
