Ontotext

Startup · Sofia, Bulgaria

Ontotext is a Sofia-based semantic-technology company that builds GraphDB, one of the leading commercial RDF-native graph databases, together with a suite of text-analysis and knowledge-graph tools used by media organizations, pharmaceutical companies, intelligence agencies, and financial institutions to turn unstructured content into structured, queryable knowledge. The BBC famously used Ontotext's semantic platform to power its 2010 World Cup and 2012 Olympics sites — one of the earliest high-profile production deployments of a knowledge graph at a major media brand — and the company has since expanded into clinical research, drug discovery, and enterprise retrieval-augmented generation (RAG) pipelines where graph-structured knowledge is paired with LLMs. Founded in 2000 as a spin-off from Sirma Group, Ontotext is a rare example of a deep, patient, deep-tech European knowledge-engineering company that predated the current AI wave and is now a load-bearing piece of several enterprise RAG stacks.
