What Zazuko does
Zazuko GmbH is a privately held, owner-managed consulting firm headquartered in Biel/Bienne, Switzerland, specializing in Semantic Web, Linked Data, and Knowledge Graph technologies. The company helps large enterprises — notably La Mobilière, a major Swiss insurer — design and implement RDF-based data architectures, including tailor-made Enterprise Data Catalogs that federate metadata from relational databases, spreadsheets, and other sources into queryable knowledge graphs. Beyond consulting and embedded development, Zazuko sells training programs to upskill client engineering teams and offers on-request commercial support for its open-source products.
Its technology stack is grounded in W3C open standards: RDF, SPARQL, and the JavaScript-based RDF/JS toolchain. The company maintains a portfolio of open-source assets including Trifid (a lightweight Linked Data server and proxy), the Zazuko Prefix Server (a public REST API for RDF namespace resolution), and JavaScript libraries such as @zazuko/rdf-vocabularies, d3-sparql, and openlayers-elements. Zazuko's CTO Thomas Bergwinkl co-chairs the W3C RDF JavaScript Libraries Community Group, and several employees contribute to RDF/JS specifications, giving the firm standards-level influence disproportionate to its small headcount (1-10 employees).
Zazuko monetizes primarily through professional services engagements and training, with a secondary, smaller revenue stream from commercial support contracts on its open-source products. Distribution mixes direct enterprise sales for consulting with self-serve developer adoption via GitHub and NPM. The company is independently owned with no disclosed parent, no institutional investors, and only minor non-dilutive grants (Venture Kick in 2010, ODINE in 2016) in its capital history.
