A retrieval engine that sits beside the existing system, reads what it already produces, and closes RFP response. Aimed at construction estimators, finding what the inspector would find, first.
In short: RFP Responder for Construction, Run by Retrieval is a retrieval engine aimed at construction estimators, covering RFP response. It scores 73/100 on AltF Ideas, carried by demand (87) and held back by monetisation (54). Typical pricing is $4.1k–$87k per customer per year, with a first version reachable in about a quarter for $17k–$55k.
Construction teams lose a 200-question RFP answered by six people over a week. The work sits between two systems that were never designed to talk. The backlog only surfaces when a customer or an auditor finds it first.
A retrieval engine that handles RFP response end to end and hands a human the exceptions rather than the queue. Revenue is per-outcome, which suits a buyer who wants the cost to track the value rather than the seat count.

| Who | The gap |
|---|---|
| An internal hire | Works until volume doubles, then breaks again |
| 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.
