We turn scattered knowledge into AI you control.
We help institutions and enterprises unify the knowledge trapped in their documents and systems, and run AI on it inside an environment they control.
About sDEN
Sovereign AI engineering for the enterprise
sDEN is a sovereign platform connecting documents, systems and experts through a governed knowledge graph. Private, explainable AI uses that shared context to answer with sources, inside an environment you control.
Fragmented knowledge becomes grounded answers, governed data sets and expert-validated records that your teams and systems can use. The evidence stays attached, so people can check the information behind a decision.
The challenge: fragmented enterprise knowledge
Knowledge is scattered across file shares, document repositories, PLM, QMS, ERP and mailboxes. Engineering, quality, legal and leadership teams struggle to find the right source, trust an AI answer and assemble evidence for compliance. Copying information into generic tools or relying on uncited answers leaves the connections unresolved, slowing decisions and exposing sensitive knowledge.Knowledge is scattered across file shares, document repositories, PLM, QMS, ERP and mailboxes.

Our solution: governed knowledge graph and explainable AI
sDEN links documents, parts, projects, suppliers, people and access rules in a governed knowledge graph, showing what is known, where it comes from and who has reviewed it. AI enriches records with source-linked metadata, experts validate what decisions depend on, and answers cite the path they took. Teams find knowledge by meaning and act with evidence.sDEN links documents, parts, projects, suppliers, people and access rules in a governed knowledge graph, showing what is known, where it comes from and who has reviewed it.
