An owner can start “Medical Bill Dispute for Services You Never Consented To” from a complaint people already posted. The offer, in one line: Ready legal wording, by state, to fight bills for ambulances and consults someone else ordered. It is for patients and consumers. Charge a fee when the job succeeds, and test a price between $10 and $49 a month. Begin in the United States. Buyers already talk about this in r/personalfinance. One thread gathered 292 votes and 151 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.

Who would pay

Patients and consumers. Start in the United States, and charge a fee when the job succeeds, testing a price between $10 and $49 a month.

The thread above is the public complaint this business can learn from. Verbatim quotes are not invented. Further sources, when a later report adds them, stay with the evidence.

What buyers use today

  • Patient advocates
  • Resolve
  • Goodbill

The offer, in our words

A dispute tool for medical bills for non-consented services (third-party-called ambulances, unrequested consults) with ready legal wording by state insurance law.

Score 3.95, Hot. Pain, willingness to pay, demand, and the gap in current options drive it. We are not scoring how fast you can code.

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

$1.3B a year

10M patients · 10% of US adults with health care debt

SAM Serviceable

$125M a year

1M patients · US, online

SOM Obtainable in 3 years

$1.3M a year

10,000 patients · 1% of the reachable segment in three years

What that means

10,000 patients a year × ~$125 = $1.2M a year in revenue

Low confidence · estimated Oct 2026

How we estimated this
  1. Base: 100,000,000 US adults with health care debt.
  2. Has the problem: 10% (assume 1 in 10 has a bill for care they did not agree to).
  3. Revenue per patient: $125 per year (25% success fee on ~$500 saved).
  4. Reachable: 10% (US, online).
  5. 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 $10–49 a month.

How should I price it?

Test a price between $10 and $49 a month, charged as a fee when the job succeeds. Raise it after three paid pilots, not before the first conversation.

Where do the first customers come from?

r/personalfinance is the clue. A related thread gathered 292 votes and 151 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. Open the founder version

A two-week build starts at $10,000 on that site, after a $1,000 scoping fee.
