This page re-scores the corpus using a weighting tuned for developers: moat 24%, demand 22%, money 18%. The same six signals, weighted for a different situation.
A reconciliation engine that sits beside the existing system, reads what it already produces, and closes reconciliation. Aimed at manufacturing ops teams, replacing the spreadsheet that currently holds it together.
A workflow engine that handles renewal management end to end and hands a human the exceptions rather than the queue. Aimed at manufacturing maintenance leads, surfacing the exposure nobody has priced.
A retrieval engine that handles customer support end to end and hands a human the exceptions rather than the queue. Aimed at energy compliance leads, at a tenth of what the enterprise suite charges.
A document parser that handles contract analysis end to end and hands a human the exceptions rather than the queue. Aimed at energy asset managers, closing the loop while everyone is asleep.
Point an anomaly detector at renewal management, and let people review output instead of producing it. Aimed at manufacturing quality teams, unbundling the one module people actually use.
