A narrow voice agent scoped to shift handover alone — no platform, no migration, no six-month rollout. Aimed at construction estimators, going after the low-value tail everyone else skips.
In short: Construction Handover Recorder on Voice is a voice agent aimed at construction estimators, covering shift handover. It scores 81/100 on AltF Ideas, carried by timing (97) and held back by monetisation (65). Typical pricing is $800–$9.0k per customer per year, with a first version reachable in about a month for $6.0k–$14k.
Construction teams lose a whiteboard that loses half of what the last crew knew. 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.
A voice agent that handles shift handover end to end and hands a human the exceptions rather than the queue. Revenue is flat saas, which suits a buyer who wants the cost to track the value rather than the seat count.

| Who | The gap |

| A generalist AI tool | No domain grounding, so output needs full human review |
| An internal hire | Works until volume doubles, then breaks again |
| The incumbent suite | Sells a platform; this job is one neglected module inside it |
The buying cycle is slower than the build, so runway assumptions matter more than code.
