A narrow retrieval engine scoped to risk assessment alone — no platform, no migration, no six-month rollout. Aimed at hvac & plumbing dispatchers, charging only when it actually works.
In short: HVAC & plumbing Risk Scorer is a retrieval engine aimed at hvac & plumbing dispatchers, covering risk assessment. It scores 73/100 on AltF Ideas, carried by demand (95) and held back by open field (29). Typical pricing is $1.0k–$20k per customer per year, with a first version reachable in six to twelve months for $31k–$68k.
HVAC & plumbing teams lose risk scored by whoever is free that afternoon. Nobody owns this process, which is exactly why it keeps breaking. The error rate is tolerated because measuring it would cost more than the errors.
Point a retrieval engine at risk assessment, and let people review output instead of producing it. 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. HVAC & plumbing is growing at roughly 16% a year, and this job has not been re-tooled since it was designed around paper.
| Who | The gap |
|---|---|
| An offshore back office | Cheaper per hour, but does not scale down to the tail |
| A spreadsheet | The real incumbent in most of the market, and it is free |
| An internal hire | Works until volume doubles, then breaks again |
Accuracy is unforgiving here — one wrong output costs more than the subscription.
