What Prairie STEM does
Mission
Prairie STEM is a nebraska not-for-profit corporation dedicated to encouraging k through 12th grade learners to investigate and follow technical career paths by sponsoring engaging and hands-on activities in the classroom and learning activities outside the classroom.
As stated on its FY2024 Form 990.
Programs
Virtual stem kits - this program includes a set of expanding lessons and materials that are offered to students, teachers and parents. A box of a set number of lessons and activities is provided along with instructions on how to utilize the items contained in the box. The students may use the stem kit on their own at home or teachers may provide stem kits to an entire classroom as a group activity.

The classroom teacher is present at all lessons learning as the students learn. As part of a school-wide plan, all teachers participate in professional development (pd) activities as arranged by the school coordinator or principal. This pd is offered during grade-level planning time, after school or on district pd days. The overarching goal is to have the school adopt the use of current trends in technology as an engaging tool for content delivery.

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 2018 to 2019, from $300k to $205k (−31%).
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.
78% of PRAIRIE STEM’s revenue is contributions — more donation-reliant than the typical peer (57% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 7 reported years ran a deficit.

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
2018 → 2023: the base broadened from 1 funder to 5 funders, grant income fell $255k → $145k.
3 of 9 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 2% 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 PRAIRIE STEM’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
PRAIRIE STEM leans on a few funders — its largest provides 69% of grant income and the top three 97%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
Largest funder’s share by year: 2018 100% · 2019 100% · 2020 99% · 2021 66% · 2022 52% · 2023 69% — 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
67% of PRAIRIE STEM's funders are still giving 2 years after their first grant; 44% 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
100% of PRAIRIE STEM's grant income comes from Nebraska funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $46k arriving through sponsors registered in 3 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.
Against its field
PRAIRIE STEM's revenue grew 43% between 2017 and 2024.
