How to start a Evidence Vault for Teacher Employment Disputes business: plan and growth
A teacher receives a written reprimand with two false accusations alongside two true ones and doesn't know whether or how to contest it. Nothing was logged as it happened.
An owner can start “Evidence Vault for Teacher Employment Disputes” from a complaint people already posted. The offer, in one line: Timestamped incident logging plus templates to formally contest a reprimand under union rules. It is for teachers and union members. Charge a subscription, and test a price under $10 a month. Begin in the United States. Buyers already talk about this in r/Teachers. One thread gathered 34 votes and 84 replies across Sep 14, 2026 – Oct 14, 2026. Use that room to meet the first twenty buyers. Do not export it, and do not republish the posts. The idea, the evidence, and the market estimate on this page are free to read. Two paid prompts finish the job: one drafts the offer, the price, and a ninety-day calendar; the other drafts a month of conversations and proof. One credit unlocks both. A software specification is not on this site. When the company is the product itself, a single link further down opens the founder library.

Market size
An estimate, built from the bottom up: real customer counts × a realistic price. It shows the size of the prize, not a forecast.
TAM Total addressable
$36M a year
750,000 teachers · 20% of US public school teachers
SAM Serviceable
$10.6M a year
220,000 teachers · reachable through teacher communities
SOM Obtainable in 3 years
$106K a year
2,200 teachers · 1% of the reachable segment in three years
What that means
2,200 teachers at $4/mo = $106K ARR
Low confidence · estimated Oct 2026
How we estimated this
- Base: 3,760,000 US public school teachers.
- Has the problem: 20% (assume 1 in 5 want a private record of workplace issues).
- Revenue per teacher: $48 per year ($4/mo).
- Reachable: 30% (reachable through teacher communities).
- Three-year capture: 1% of the reachable segment.
TAM is customers with the problem × revenue per customer. SAM is the part a new business can reach. SOM is a cautious three-year share of SAM. The bars use a log scale. A share marked “assume” is our judgment, not a measurement.

Questions
How much money do I need to start?
Enough to talk to buyers and deliver the offer once. A service version can start with a written process and a way to take payment. A software version is a larger bet and is not required to test the price. The band to test is Under $10 a month.
How should I price it?
Test a price under $10 a month, charged as a subscription. Raise it after three paid pilots, not before the first conversation.
Where do the first customers come from?
r/Teachers is the clue. A related thread gathered 34 votes and 84 replies. Show up there, follow the room's rules, and ask for conversations. Do not scrape it.
Do I need to write code?
No. The prompts on this page draft a plan and a month of growth. Code is a later choice. The founder site linked once below is where the build document lives, if you want it.
A separate site sells the agent build document and can build the product. Read the agent PRD
A two-week build starts at $10,000 on that site, after a $1,000 scoping fee.
