Point a reconciliation engine at margin monitoring, and let people review output instead of producing it. Aimed at construction project managers, at a tenth of what the enterprise suite charges.
Point a classifier at lead qualification, and let people review output instead of producing it. Aimed at construction ops teams, starting from data the business already produces.
Point a document parser at compliance audit, and let people review output instead of producing it. Aimed at construction owner-operators, at a tenth of what the enterprise suite charges.
Permit & licence tracking handled by a change monitor, with a human signing rather than writing. Aimed at construction estimators, unbundling the one module people actually use.
Point an anomaly detector at inventory planning, and let people review output instead of producing it. Aimed at architecture project architects, taking the phone queue off a human entirely.
A narrow document parser scoped to intake & triage alone — no platform, no migration, no six-month rollout. Aimed at real estate property managers, holding service constant on a smaller team.
Point a forecasting model at margin monitoring, and let people review output instead of producing it. Aimed at property management owner-operators, finding what the inspector would find, first.
Point a document parser at pricing, and let people review output instead of producing it. Aimed at construction project managers, unbundling the one module people actually use.
