A narrow retrieval engine scoped to RFP response alone — no platform, no migration, no six-month rollout. Aimed at construction estimators, holding service constant on a smaller team.
In short: RFP Responder Built for Estimators is a retrieval engine aimed at construction estimators, covering RFP response. It scores 72/100 on AltF Ideas, carried by monetisation (97) and held back by feasibility (27). Typical pricing is $4.2k–$90k per customer per year, with a first version reachable in six to twelve months for $42k–$113k.
Construction teams lose a 200-question RFP answered by six people over a week. A typical construction operation runs this on people, memory, and a shared spreadsheet. The backlog only surfaces when a customer or an auditor finds it first.
Point a retrieval engine at RFP response, and let people review output instead of producing it. 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 |
|---|---|
| A generalist AI tool | No domain grounding, so output needs full human review |
| An internal hire | Works until volume doubles, then breaks again |
| A vertical competitor | Priced and scoped for enterprise accounts, not this segment |
The incumbent is a person, and displacing a person is a change-management problem.
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.
