What Semantic Web Company does

Semantic Web Company GmbH, founded in 2004 in Vienna, Austria, is a private provider of semantic web infrastructure technologies and knowledge graph solutions. The company builds the PoolParty Semantic Suite, a semantic middleware platform that enables enterprises to model taxonomies and ontologies, extract and annotate concepts from text, run semantic search and recommender systems, and expose knowledge graphs via SPARQL endpoints and REST APIs using W3C standards (SKOS, RDF). PoolParty for SharePoint and PoolParty Academy extend the platform into Microsoft SharePoint environments and certified e-learning, respectively.

SWC serves a global base of more than 150 enterprise and government customers across at least seven verticals, including Harvard Business School, Credit Suisse, Philips, Wolters Kluwer, the World Bank, Boehringer Ingelheim, Fluor, Oxford University Press, Health Direct, the United Nations, and (post-merger) Avalara. Revenue is generated through enterprise software licensing (subscription/recurring), consulting and integration services, and training services. Distribution is direct and enterprise field-sales led, supported by offices in Vienna, Boston, and London, the annual SEMANTiCS conference, and the PoolParty Academy developer community.

In October 2024, Semantic Web Company merged with Bulgaria-based Ontotext to form Graphwise, combining SWC's semantic AI expertise with Ontotext's graph database and text mining capabilities. The combined entity subsequently launched the Graph AI Suite in October 2025 and the GraphRAG technology in February 2026, targeting enterprises seeking to deploy LLMs in production with verifiable, low-hallucination answers. The company operates with 51-100 employees across Europe and North America.

Core offering

Semantic Web Company develops and licenses the PoolParty Semantic Suite, a semantic middleware platform that enterprises use to build, manage and query knowledge graphs, taxonomies and ontologies, augmented by consulting/integration services and training delivered through PoolParty Academy. Following its October 2024 merger with Ontotext (forming Graphwise), the offering has been extended with the Graph AI Suite and GraphRAG to provide an integrated graph database plus retrieval-augmented-generation stack for enterprise LLM deployments.

Product overview

Semantic Web Company offers the PoolParty Semantic Suite as its core product, a semantic middleware platform for enterprise knowledge graph applications. The platform integrates knowledge modelling, text extraction, semantic search, and recommendation capabilities via SPARQL endpoints. Add-on modules include PoolParty for SharePoint (SharePoint integration) and PoolParty Academy (e-learning). In October 2024, Semantic Web Company merged with Ontotext to form Graphwise, expanding the product portfolio to include GraphRAG and Graph AI Suite for AI-powered knowledge graph solutions.

Scale indicators5 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Collibra: Enterprise data intelligence and governance platform with data catalog, lineage, and metadata capabilities. Adjacent to PoolParty's semantic middleware in metadata management and data governance use cases, but operates at a broader and more horizontal scale.
• Neo4j: Leading native graph database vendor serving enterprise knowledge graph, fraud detection, and recommendation use cases. Broader platform incumbent with a much larger installed base; competes with SWC/Graphwise for graph-backed AI workloads but does not focus on semantic middleware for taxonomy/ontology management.
• Alation: Data catalog and metadata management vendor for enterprise data teams. Adjacent competitor in metadata and knowledge organization; less semantic-AI-native than PoolParty but competes for similar data governance budgets in regulated industries.

Emerging players

• TigerGraph: Graph database and analytics vendor focused on enterprise-scale graph ML and AI applications. Competes with Graphwise for graph-powered enterprise AI workloads, but with a proprietary (non-RDF) graph model versus SWC's W3C standards approach.
• Data.world: Cloud-native enterprise knowledge graph and data catalog platform built on W3C standards. Overlaps with PoolParty in knowledge graph and metadata cataloging use cases for data teams; competes more on modern cloud/SaaS GTM versus SWC's enterprise-led model.

Direct peers

• Stardog: Enterprise knowledge graph platform offering Stardog Studio and a W3C standards-based graph database with virtualized data access. Directly comparable to PoolParty in target buyer (large enterprises), semantic technology stack, and use cases around data integration and knowledge management.
• Ontotext: Graph database and text analytics vendor that merged with Semantic Web Company in October 2024 to form Graphwise. Historically the most direct peer — overlapping enterprise knowledge-graph customers, complementary technology stacks, and shared European market focus.
• Cambridge Semantics: Enterprise semantic graph and metadata management vendor (Anzo platform) serving financial services, life sciences, and government. Directly comparable to PoolParty on semantic knowledge graph use cases for data integration, governance, and analytics.
• Franz Inc. Provider of AllegroGraph, an RDF/SPARQL graph database, and Common Lisp-based AI tools serving enterprise knowledge graph and semantic AI workloads. Direct standards-based peer to PoolParty/Graphwise with overlapping semantic technology stack and enterprise customers.
• TopQuadrant: Vendor of TopBraid Enterprise Data Governance and semantic technology tools for taxonomy, ontology, and metadata management. Direct peer in the W3C-based enterprise semantic middleware category, with similar buyers in publishing, life sciences, and government.
