A retrieval engine that sits beside the existing system, reads what it already produces, and closes knowledge capture. Aimed at construction owner-operators, taking the phone queue off a human entirely.
Point a document parser at quoting & estimating, and let people review output instead of producing it. Aimed at construction project managers, unbundling the one module people actually use.
Asset tracking handled by an anomaly detector, with a human signing rather than writing. Aimed at construction owner-operators, closing the loop while everyone is asleep.
Construction/Usage-based/$2.5k ACV/~1 month
A retrieval engine that handles proposal writing end to end and hands a human the exceptions rather than the queue. Aimed at construction estimators, charging only when it actually works.
Construction/Managed service/$11k ACV/~1 quarter
A narrow document parser scoped to claims & appeals alone — no platform, no migration, no six-month rollout. Aimed at construction estimators, going after the low-value tail everyone else skips.
Construction/Per-project/$3.4k ACV/~1 quarter
A retrieval engine that sits beside the existing system, reads what it already produces, and closes risk assessment. Aimed at construction estimators, going after the low-value tail everyone else skips.

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.
Construction/Flat SaaS/$800 ACV/~1 month
Intake & triage handled by a document parser, with a human signing rather than writing. Aimed at construction estimators, finding what the inspector would find, first.
Construction/Managed service/$11k ACV/~1 quarter
Point an autonomous agent at collections, and let people review output instead of producing it. Aimed at construction project managers, catching the error before it becomes a change order.
Construction/Seat SaaS/$1.0k ACV/6-12 months
Collections handled by a forecasting model, with a human signing rather than writing. Aimed at construction project managers, holding service constant on a smaller team.
Construction/Usage-based/$2.6k ACV/~1 quarter
A forecasting model that sits beside the existing system, reads what it already produces, and closes renewal management. Aimed at construction project managers, so the work stops following people home.
A vision model that handles compliance audit end to end and hands a human the exceptions rather than the queue. Aimed at construction project managers, finding what the inspector would find, first.
A narrow document parser scoped to compliance audit alone — no platform, no migration, no six-month rollout. Aimed at construction project managers, charging only when it actually works.
Construction/Per-outcome/$4.1k ACV/Weekend
