How to start a Proposal Tool That Protects Your Ideas business: plan and growth
An agency spent two days on a detailed proposal and the prospect simply implemented it with a cheaper freelancer: intellectual work stolen at the sales stage.
An owner can start “Proposal Tool That Protects Your Ideas” from a complaint people already posted. The offer, in one line: Show the full value of a proposal but gate implementation details behind a paid discovery phase, with view tracking. It is for freelancers and agencies. Charge a subscription, and test a price between $10 and $49 a month. Begin in more than one country. Buyers already talk about this in r/freelance. One thread gathered 82 votes and 63 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.

The offer, in our words
A proposal builder that shows the solution's value but hides the technical how-to behind a paid discovery step, with watermarks and document view tracking.
Score 3.65, 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
$1.5B a year
6.4M freelancers · 10% of Americans who freelanced in the past year
SAM Serviceable
$312M a year
1.3M freelancers · English-speaking, online
SOM Obtainable in 3 years
$3.1M a year
13,000 freelancers · 1% of the reachable segment in three years
What that means
13,000 freelancers at $20/mo = $3.1M ARR
Medium confidence · estimated Oct 2026
How we estimated this
- Base: 64,000,000 Americans who freelanced in the past year.
- Has the problem: 10% (assume 1 in 10 write proposals regularly).
- Revenue per freelancer: $240 per year ($20/mo).
- Reachable: 20% (English-speaking, online).
- 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 subscription. Raise it after three paid pilots, not before the first conversation.
Where do the first customers come from?
r/freelance is the clue. A related thread gathered 82 votes and 63 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.
When the business is the software itself, the specification lives on the founder site. PRD and build options
A two-week build starts at $10,000 on that site, after a $1,000 scoping fee.
