A narrow retrieval engine scoped to proposal writing alone — no platform, no migration, no six-month rollout. Aimed at construction estimators, unbundling the one module people actually use.
In short: Retrieval-Powered Proposal Builder for Estimators is a retrieval engine aimed at construction estimators, covering proposal writing. It scores 78/100 on AltF Ideas, carried by moat (96) and held back by feasibility (42). Typical pricing is $3.7k–$78k per customer per year, with a first version reachable in six to twelve months for $29k–$96k.
Construction teams lose proposals rebuilt from scratch that are 80% identical. It is the kind of task that is too small to fund and too costly to ignore. It scales linearly with headcount, so growth makes it worse rather than better.
A retrieval engine that sits beside the existing system, reads what it already produces, and closes proposal writing. Revenue is per-outcome, which suits a buyer who wants the cost to track the value rather than the seat count.

Retrieval over private documents became cheap enough to run per query. Construction is growing at roughly 20% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
| A spreadsheet | The real incumbent in most of the market, and it is free |
| A generalist AI tool | No domain grounding, so output needs full human review |
Every customer wants their own edge cases encoded, so onboarding cost is the real constraint.
An idea you cannot act on is entertainment. Four concrete steps, wired to tools already running on AltFTool.
Score problem urgency, willingness to pay, and reachable audience size before writing any code.
→ AltF IdeaLabAsk how they handle this today and what it costs them. If nobody can quantify the pain, the demand score is optimistic.
→ Survey BuilderCheck availability, DNS, and email authentication in one pass so your first outreach lands in an inbox.
→ AltF DomainOpsStand up intake, the review queue, and billing before you build the clever part.
