Ontotext
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.

Payhawk
Payhawk is a Sofia-founded fintech company focused on spend management for multi-entity businesses. The platform combines corporate cards, expense controls, reimbursements, accounts payable workflows, and accounting integrations into one system designed for finance teams that need real-time visibility over company spending. That matters because expense management becomes significantly more complex once a business expands across countries, currencies, and legal entities. Payhawk's strength is in turning those fragmented workflows into a more controlled operational system that links employee spending directly to approval logic and ERP records. In the European startup ecosystem, Payhawk is notable both as a major Bulgarian success story and as an example of enterprise fintech that sells into sophisticated finance organizations rather than only SMB card use cases. It therefore sits close to travel, procurement, and financial operations infrastructure, making it a useful link between SaaS workflow tooling and regulated finance systems.
