What American Institute of Mathematics does
Mission
The institute was founded with the primary goal of identifying and solving important mathematical problems.
As stated on its FY2024 Form 990.
Programs
Aim research conference center (arcc): a model for collaborative researcharcc hosts focused workshops in all areas of the mathematical sciences. Arcc focused workshops are distinguished by their emphasis on a specific mathematical goal, such as making progress on a significant unsolved problem, understanding the proof of an important new result, or examining the convergence of two distinct areas of mathematics.aim focused workshops provide an ideal forum for a team of researchers working together to map out strategies, set priorities, work toward a solution, and set in place a framework for progress on important mathematical problems. The leaders in each field are involved in the planning of the workshops, and junior scientists and graduate students are active participants. Special attention is devoted to facilitate collaborations which include women, minorities, and researchers at primarily undergraduate institutions.the purpose of aim's research program called squares (structured quartet research ensembles) is to allow a dedicated group of four to six mathematicians to spend a week at aim in pasadena, california with the possibility of returning in following years. A square…
$3,527,622 spent85% of program spendingDirected grants:the following directed grants were active during the year:1. Collaborative research: aim & icerm research experience for undergraduate faculty (reuf)enabling more americans to earn undergraduate degrees in science, technology, engineering and mathematics (stem) is important to improving american innovation capabilities. Participating in research as undergraduates improves retention in stem majors and encourages students to pursue graduate degrees. Faculty at colleges and universities that focus on undergraduate education are critical to this mission, yet in many cases such faculty receive little support to do research with the students they teach or continue their own research, and doctoral programs often fail to train their graduates to mentor undergraduate research. To address this need, the American Institute of Mathematics and the institute for computational and experimental research in mathematics conducted a series of four annual research experiences for undergraduate faculty (reuf) workshops during the summers of 2021, 2022, 2023 and 2024. Progress continued through the year by the pi.2. Collaborative research: utmost: undergraduate teaching in mathematics…

Math festivals & math outreach projectsvarious activities and projects that support locally organized events that inspire k-12 students to expore mathematics through collaborative, creative problem-solving.5. A distributed learning environment for the mathematics of climate and sustainabilitythe research project focus will be on the mathematics needed for understanding our climate, its impacts and will help address the pressing issues of adaptation and sustainability in light of inevitable changes. Through this program, four cohorts of students will be trained in the mathematics underlying te all-important societal and scientific issues emanating from climate and sustainability. This will span a five-year period and encompass four intensive week-long summer camps.each cohort will consist of seven graduate and three undergarduate students. They will be trained in collaborative team-work that will prepare them well for a career in any scientific endeavor involving mathematical investigation. Each year will include online training to prepare the students for the summer camp and ongoing focus research groups during the subsequent academic year, during which…
The 3 programs described on its FY2024 Form 990, listed largest first by expense. Program spending in total: $4,125,980.
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.
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 $1.7M to $3.1M (+83%).
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 82% · 2018 69% · 2019 58% · 2020 70% · 2021 73% · 2022 86% · 2023 91% · 2024 86%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 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 3 funders to 6 funders, grant income fell $432k → $317k.
8 of 22 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 45% 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 AMERICAN INSTITUTE OF MATHEMATICS’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
AMERICAN INSTITUTE OF MATHEMATICS leans on a few funders — its largest provides 41% of grant income and the top three 84%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
52% 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 AMERICAN INSTITUTE OF MATHEMATICS.
Largest funder’s share by year: 2017 89% · 2018 56% · 2019 77% · 2020 30% · 2021 51% · 2022 98% · 2023 87% — 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
27% of AMERICAN INSTITUTE OF MATHEMATICS's funders are still giving 3 years after their first grant; 55% 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
67% of AMERICAN INSTITUTE OF MATHEMATICS's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $2.4M 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.

Federal grants vs contracts are distinguished; state line items keep their reported category. Matched by name + geography (the BMF), so coverage is partial and precision-first.
