What Semantic Partners does
Semantic Partners is a UK-headquartered professional services consultancy specialising in knowledge graph and ontology engineering for enterprise customers. Founded in 2021 by Dan Collier, John Placek, and Lance Paine, the firm designs and deploys formal semantic models built on W3C standards (OWL, RDF, SHACL, SKOS, SPARQL) and implements them on a technology-agnostic basis across five partner platforms: Stardog, GraphDB, RDFox, Fluree, and eccenca Corporate Memory. To date the firm reports 50+ enterprise ontologies built and 100M+ triples under management across 12 industries including financial services, pharma, manufacturing, government, automotive, telecommunications, and retail. Named customers include Siemens, UBS, GSK, HSBC, BMW, Rolls-Royce, NatWest, BT, DNB, and Allianz.
The company delivers through eight core services covering ontology strategy and advisory, formal ontology engineering, end-to-end knowledge graph build and implementation, semantic AI architecture, governance frameworks, vendor selection, and AI systems integration, supported by four instructor-led training programmes (Introduction to Knowledge Graphs, Advanced Knowledge Graphs, Ontology Design, and Advanced SHACL). Its commercial model combines multi-year consulting engagements with channel resale and recurring maintenance, supplemented by an emerging training catalogue. Distribution is anchored on direct enterprise field sales augmented by a structured partner ecosystem: a 2024 EMEA channel partnership with Altair for data analytics and knowledge graph resale; strategic alliances with metaphacts, eccenca, Fluree, Squirro, and the SFIA Foundation; implementation partnerships with systems integrators (Cognizant, Coforge, Credera, Computacenter, Matogen, Adorsys, ZS); and an academic collaboration with the University of Malta.
Operational signals — a 97% staff retention rate, a large PhD-heavy engineering bench, recent productised releases (SFIA 9 in RDF, Advanced SHACL), accelerated partnership cadence through 2024–2025, and Cyber Essentials Plus plus Siemens RapidMiner Expert Partner credentials — indicate a maturing, premium-positioning consultancy scaling through channel leverage and reusable IP rather than large headcount expansion.
