A workflow engine that sits beside the existing system, reads what it already produces, and closes grant & funding tracking. Aimed at manufacturing plant supervisors, taking the phone queue off a human entirely.
An anomaly detector that handles maintenance planning end to end and hands a human the exceptions rather than the queue. Aimed at manufacturing ops teams, catching the error before it becomes a change order.
Training & competency handled by a forecasting model, with a human signing rather than writing. Aimed at energy ops teams, closing the loop while everyone is asleep.
Reporting & analytics handled by a reconciliation engine, with a human signing rather than writing. Aimed at solar project managers, starting from data the business already produces.
A narrow reconciliation engine scoped to invoicing alone — no platform, no migration, no six-month rollout. Aimed at hospitality general managers, built for one person, not a department.
Point a document parser at grant & funding tracking, and let people review output instead of producing it. Aimed at manufacturing plant supervisors, closing the loop while everyone is asleep.

Manufacturing/Per-outcome/$5.1k ACV/~1 quarter
A narrow optimisation engine scoped to maintenance planning alone — no platform, no migration, no six-month rollout. Aimed at manufacturing ops teams, surfacing the exposure nobody has priced.
A forecasting model that sits beside the existing system, reads what it already produces, and closes renewal management. Aimed at manufacturing ops teams, charging only when it actually works.

Energy/Usage-based/$2.3k ACV/Weekend
A retrieval engine that sits beside the existing system, reads what it already produces, and closes contract analysis. Aimed at energy asset managers, starting from data the business already produces.
Energy/Per-outcome/$4.4k ACV/~1 month
A forecasting model that handles quoting & estimating end to end and hands a human the exceptions rather than the queue. Aimed at energy asset managers, unbundling the one module people actually use.
Energy/Seat SaaS/$1.2k ACV/~1 month
Solar/Seat SaaS/$1.0k ACV/~1 month
