What Mariners Inn does
Mission
To provide 24-hour residential substance abuse treatment for adult homeless men in a professional, compassionate, and therapeutic environment conducive to reducing drug and alcohol addiction and promoting their return to health, independence, and increased self-worth.
As stated on its FY2025 Form 990.
Programs
The residential treatment program continued to service men who were homeless, at least 18 years of age, and chemically dependent by providing approximately 81 beds and up to 29 days of treatment.
$1,747,559 spent$86,743 earned by the program40% of program spendingThe recovery housing program provided a supportive, semi-independent living experience to men who successfully completed the residential treatment program. The men received living space and meals in a recovering community of sober men for a period of usually four months. The program also gave these men the opportunity to work on all aspects of their recovery from substance abuse and homelessness. Each individual worked on his own specific goals (I.e., his particular way of being self-sufficient), established with the assistance of the recovery housing staff.
$1,137,966 spent$56,485 earned by the program26% of program spendingThe extended residency program provided an alcohol-free and drug-free residential environment in which men were offered living space and meals in a recovering community for an initial period of up to two years. The program provided permanent housing for homeless men with disabilities and is based on the principles of the 12-step recovery model for substance abuse.

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 2022 to 2023, from $7.4M to $11M (+44%).
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: 2017 83% · 2018 82% · 2019 81% · 2020 72% · 2021 84% · 2022 39% · 2023 76% · 2024 85% · 2025 68%. Grants only. Government contracts and fees sit inside program revenue.
88% of MARINERS INN’s revenue is contributions — more donation-reliant than the typical peer (51% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 7 funders to 13 funders, grant income rose $39k → $637k.
9 of 41 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 11% 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 MARINERS INN’s funders (the co-funder graph). Top 30 of 41 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
MARINERS INN leans on a few funders — its largest provides 48% of grant income and the top three 60%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
29% 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 MARINERS INN.
Largest funder’s share by year: 2017 44% · 2018 33% · 2019 45% · 2020 46% · 2021 27% · 2022 71% · 2023 79% — growing more concentrated.
“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
45% of MARINERS INN's funders are still giving 3 years after their first grant; 46% 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
96% of MARINERS INN's grant income comes from Michigan funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $238k arriving through sponsors registered in 9 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.
