Point a retrieval engine at RFP response, and let people review output instead of producing it. Aimed at rail ops teams, holding service constant on a smaller team.
In short: Rail RFP Responder on Retrieval is a retrieval engine aimed at rail ops managers, covering RFP response. It scores 71/100 on AltF Ideas, carried by moat (96) and held back by demand (31). Typical pricing is $800–$16k per customer per year, with a first version reachable in a weekend for $2.0k–$7.0k.
Rail teams lose a 200-question RFP answered by six people over a week. A typical rail operation runs this on people, memory, and a shared spreadsheet. It scales linearly with headcount, so growth makes it worse rather than better.
A retrieval engine that handles RFP response end to end and hands a human the exceptions rather than the queue. Revenue is seat saas, 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. Rail is growing at roughly 10% 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 |
| A generalist AI tool | No domain grounding, so output needs full human review |
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
Accuracy is unforgiving here — one wrong output costs more than the subscription.
