What MIO Frontiers does
Mission
Church planting among the least evangelized peoples of the world through recruiting, training, sending, and serving field workers.
As stated on its FY2020 Form 990.
Program
The mission of Frontiers is to plant churches that lead to movements among the least evangelized people of the world. Expenses are related to various functions of carrying on this work during the current year. These expenses include training, recruiting, preparing, and supporting the work of the fieldworkers. Some of the various events and programs include: - Candidate School: Event held twice to three times a year to evaluate and train potential fieldworkers.- Recruiting Events: Mobilization events held in the US to identify potential candidates for overseas fieldwork.- Member Care Events: Events held to debrief and improve the spiritual health of fieldworkers who have experienced life-changing events. - Training: Region specific training for fieldworkers.- Church-Based Team Events - Events held to prepare church-based teams for the transition to the field.

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 2019 to 2020, from $18M to $21M (+15%).
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.
99% of MIO Frontiers’s revenue is contributions — more reliant on donations than three-quarters of its peers (84% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 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
2017 → 2023: the base broadened from 30 funders to 58 funders, grant income rose $1.2M → $3.2M.
44 of 148 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 78% 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 MIO Frontiers’s funders (the co-funder graph). Top 30 of 148 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
MIO Frontiers has a broad base — no single funder exceeds 26% 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
86% 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 MIO Frontiers.
Largest funder’s share by year: 2017 23% · 2018 44% · 2019 45% · 2020 31% · 2021 29% · 2022 23% · 2023 24% — broadly stable.
“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
51% of MIO Frontiers's funders are still giving 3 years after their first grant; 60% 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
78% of MIO Frontiers'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 $4.9M that is directly attributable, 89% of it comes from funders outside Arizona, across 31 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $17M arriving through sponsors registered in 24 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.
