Proposal Tool That Protects Your Ideas is a startup idea for freelancers and agencies. 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. A thread in r/freelance drew 82 upvotes and 63 comments between Sep 14, 2026 – Oct 14, 2026. People get by with PandaDoc, Proposify, and DocSend, and that still leaves this job open. Hotness is 3.65, Hot. Strong pain. Clear willingness to pay. The thread drew 82 upvotes and 63 comments. Gaps in existing tools. A few weeks of work. A first version is a moderate amount of work, about 3–4 weeks, priced between $10 and $49 a month and charged as a subscription. 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.

A way through
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.
MVP scope
- Give freelancers and agencies a way to do this in one sitting: Show the full value of a proposal but gate implementation details behind a paid discovery phase, with view tracking.
- Persist the result and show it again after a reload.
- State the empty case when there is nothing to show yet, with one next step.
- Charge later with a subscription, between $10 and $49 a month. The free path must finish the core job once.
- Ship the web app only. Leave PandaDoc to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use PandaDoc, Proposify, DocSend. 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?
Moderate. A tight MVP is about 3 weeks (3–4 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 freelancers and agencies. Charge a subscription, and test a price between $10 and $49 a month. 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.
