A narrow retrieval engine scoped to compliance audit alone — no platform, no migration, no six-month rollout. Aimed at rail maintenance leads, writing down what only one person knows.
In short: Retrieval Compliance Auditor for Rail is a retrieval engine aimed at rail maintenance leads, covering compliance audit. It scores 70/100 on AltF Ideas, carried by moat (97) and held back by demand (29). Typical pricing is $11k–$172k per customer per year, with a first version reachable in about a quarter for $16k–$51k.
Rail teams lose an audit prepared in a two-week panic every year. A typical rail operation runs this on people, memory, and a shared spreadsheet. Whoever knows how it works becomes a single point of failure.
Point a retrieval engine at compliance audit, and let people review output instead of producing it. 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. 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 |
|---|---|
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
| 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 |
Every customer wants their own edge cases encoded, so onboarding cost is the real constraint.
