It scores 75/100 on AltF Ideas, carried by moat (89) and held back by feasibility (31). Typical pricing is $6.9k–$138k per customer per year, with a first version reachable in six to twelve months for $41k–$100k.
Construction teams lose discovering a product went underwater a quarter late. The work sits between two systems that were never designed to talk. The error rate is tolerated because measuring it would cost more than the errors.
Margin monitoring handled by an anomaly detector, with a human signing rather than writing. Revenue is take-rate, 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 generalist AI tool | No domain grounding, so output needs full human review |
| A vertical competitor | Priced and scoped for enterprise accounts, not this segment |
| An internal hire | Works until volume doubles, then breaks again |
Integrations with the incumbent system of record are undocumented and gatekept.
