Headquarters evidence
Ontotext is headquartered in Sofia, Bulgaria.
The research candidate suggested 'EU headquarters', but its exact quote could not be reproduced from the cited current source; the claim remains unpromoted.
Evidence boundaries
Organisation listings identify a reviewed canonical record. Headquarters is independent of incorporation, registered offices, ownership, hosting and runtime. Model listings show an association in the source register; they do not by themselves establish model creation, current API availability, hosting location or infrastructure ownership.

Profile note
Bulgaria's oldest and best-known semantic-AI company (founded 2000). Not an LLM lab: it supplies the knowledge-graph substrate for GraphRAG — broad LLM compatibility, no-code RAG chat in GraphDB Workbench, LangChain NL querying, MCP support for agentic AI, and precision entity linking pitched as hallucination control. Note the corporate change: the product now sits under the Graphwise brand (Vienna/Sofia/New York) following the Semantic Web Company merger. Enterprise pricing is gated.
