Point a workflow engine at vendor management, and let people review output instead of producing it. Aimed at manufacturing plant supervisors, replacing the spreadsheet that currently holds it together.
Point a document parser at claims & appeals, and let people review output instead of producing it. Aimed at manufacturing maintenance leads, unbundling the one module people actually use.
A document parser that handles warranty & returns end to end and hands a human the exceptions rather than the queue. Aimed at energy ops teams, proving value before anyone signs anything.
A narrow anomaly detector scoped to reconciliation alone — no platform, no migration, no six-month rollout. Aimed at energy ops teams, unbundling the one module people actually use.
A document parser that sits beside the existing system, reads what it already produces, and closes invoicing. Aimed at energy asset managers, built for one person, not a department.
Point a document parser at reporting & analytics, and let people review output instead of producing it. Aimed at waste management ops teams, unbundling the one module people actually use.
A document parser that sits beside the existing system, reads what it already produces, and closes compliance audit. Aimed at manufacturing plant supervisors, going after the low-value tail everyone else skips.
Manufacturing/Managed service/$11k ACV/~1 month
Point a retrieval engine at grant & funding tracking, and let people review output instead of producing it. Aimed at manufacturing ops teams, so the work stops following people home.
