A voice agent that sits beside the existing system, reads what it already produces, and closes shift handover. Aimed at construction estimators, finding what the inspector would find, first.

Construction teams lose a whiteboard that loses half of what the last crew knew. It is the kind of task that is too small to fund and too costly to ignore. The error rate is tolerated because measuring it would cost more than the errors.
A narrow voice agent scoped to shift handover alone — no platform, no migration, no six-month rollout. Revenue is managed service, which suits a buyer who wants the cost to track the value rather than the seat count.
