Point a retrieval engine at proposal writing, and let people review output instead of producing it. Aimed at construction ops teams, starting from data the business already produces.
In short: Construction Proposal Builder is a retrieval engine aimed at construction ops managers, covering proposal writing. It scores 75/100 on AltF Ideas, carried by demand (96) and held back by feasibility (56). Typical pricing is $12k–$187k per customer per year, with a first version reachable in about a quarter for $15k–$51k.
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. Most operators assume this is simply the cost of doing business.
A narrow retrieval engine scoped to proposal writing alone — no platform, no migration, no six-month rollout. Revenue is managed service, 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 |
|---|---|
| An internal hire | Works until volume doubles, then breaks again |
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
| A generalist AI tool | No domain grounding, so output needs full human review |
Trust has to be earned before anyone lets this run unsupervised.
