A voice agent that handles inspection end to end and hands a human the exceptions rather than the queue. Aimed at hvac & plumbing field supervisors, charging only when it actually works.
In short: Inspection Assistant Built for Field Supervisors is a voice agent aimed at hvac & plumbing field supervisors, covering inspection. It scores 74/100 on AltF Ideas, carried by demand (95) and held back by open field (39). Typical pricing is $3.2k–$68k per customer per year, with a first version reachable in about a quarter for $14k–$46k.
HVAC & plumbing teams lose inspections written up twice — once on paper, once at night. A typical hvac & plumbing operation runs this on people, memory, and a shared spreadsheet. It scales linearly with headcount, so growth makes it worse rather than better.
Point a voice agent at inspection, and let people review output instead of producing it. Revenue is per-outcome, 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 offshore back office | Cheaper per hour, but does not scale down to the tail |
| An internal hire | Works until volume doubles, then breaks again |
The incumbent is a person, and displacing a person is a change-management problem.
