Prometheux is building the ontology-native infrastructure for operational AI. Reliable AI in enterprise faces two major problems:1. The model problem: Frontier models are probabilistic, unpredictably expensive, slow, and un-auditable for regulated industries. They are compilations of averages that don't understand your unique business logic — your competitive advantage.2. The data problem: Enterprise data is fragmented and means nothing without context. Multiple disconnected systems with inconsistent business definitions and siloed operational knowledge, pieced together by static dashboards and brittle pipelines.Prometheux turns business logic into executable ontologies that process data wherever it lives — across databases, warehouses, and cloud platforms — without migrations or duplication.
