A narrow anomaly detector scoped to margin monitoring alone — no platform, no migration, no six-month rollout. Aimed at construction estimators, holding service constant on a smaller team.
In short: Automated Margin Watch for Construction is an anomaly detector aimed at construction estimators, covering margin monitoring. It scores 72/100 on AltF Ideas, carried by open field (84) and held back by moat (50). Typical pricing is $900–$9.0k per customer per year, with a first version reachable in about a month for $6.0k–$17k.
Construction teams lose discovering a product went underwater a quarter late. 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 an anomaly detector at margin monitoring, and let people review output instead of producing it. Revenue is flat saas, which suits a buyer who wants the cost to track the value rather than the seat count.

Streaming detection became practical without a dedicated data platform. 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 vertical competitor | Priced and scoped for enterprise accounts, not this segment |
| An internal hire | Works until volume doubles, then breaks again |
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
Accuracy is unforgiving here — one wrong output costs more than the subscription.
