FoxyDB · The intelligence runtime

The knowledge graph built for the AI era.

An ontological layer that remembers everything, reacts instantly with action, infers new facts, and builds policy and governance into every decision. FoxyDB is the deterministic runtime under Foxy — the logic half of neurosymbolic.

tenant: yours

Remembers. Infers. Acts. Answers for it.

Infer new knowledge

OWL2 RL and Datalog materialization: facts nobody wrote down, derived the moment their premises land, kept current as data changes.

React instantly with action

Change-data-capture triggers fire reactive rules the moment the graph changes. Not a query engine you poll — a runtime that acts.

Policy in the substrate

Attribute-level policy, data lineage, and bitemporal history. Governance built in, not bolted on — every read and write answers to it.

Hosted or private

Single-tenant by default. Run it in our cloud or entirely inside yours; either way, your ontology and your data stay yours.

Your business, in languages that compute.

Open standards — RDF, OWL2, Datalog — not a proprietary schema. Like code, but for how your business thinks.

% fires the moment the premises hold — no polling

FoxyDB is the runtime under everything we ship.

It doesn’t ship alone — it ships inside Foxy, doing the remembering and the reasoning while the models do the talking.
