Micro-Crowdfunding for Classroom Supplies is a startup idea for teachers, parents, and local communities. A school ran out of printer paper because of budget cuts: not equipment, just basic consumables without which the school literally can't print. A thread in r/Teachers drew 66 upvotes and 60 comments between Sep 14, 2026 – Oct 14, 2026. People get by with DonorsChoose, Amazon wish lists, and PTA fundraising, and that still leaves this job open. Hotness is 2.75, Simmering. Real but moderate pain. Price-sensitive audience. The thread drew 66 upvotes and 60 comments. Crowded with decent tools. A 1-2 week mvp. A first version is weekend-easy, about 2 weeks, priced as a fee on each transaction and charged as a fee on each transaction. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Market size · estimate
How big this could get
A bottom-up estimate for Micro-Crowdfunding for Classroom Supplies: real customer counts × a realistic price. Not a forecast.
$76M a year
1.9M teachers · 50% of US public school teachers
$22.8M a year
570,000 teachers · US public schools that allow it
$228K a year
5,700 teachers · 1% of the reachable segment in three years
What that means
5,700 teachers a year × ~$40 = $228K a year in revenue
Medium confidenceHow we estimated this
- Base: 3,760,000 US public school teachers.
- Has the problem: 50% (most teachers buy supplies with their own money; assume half would raise funds).
- Revenue per teacher: $40 per year (8% fee on ~$500 raised a year).
- Reachable: 30% (US public schools that allow it).
- Three-year capture: 1% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Is this idea already taken?
People already use DonorsChoose, Amazon wish lists, PTA fundraising. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Weekend-easy. A tight MVP is about 2 weeks (2 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is teachers, parents, and local communities. Charge a fee on each transaction, and test a price as a fee on each transaction. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
