Neo4j

Neo4j builds graph databases, analytics, and AI tools that let developers and enterprises query connected data, investigate relationships, and supply context to AI applications. Neo4j Aura offers managed database, analytics, and agent tools; self-managed Graph Database and Graph Data Science products run within customers’ infrastructure. Native vector search complements knowledge graphs for AI retrieval. Neo4j completed its acquisition of GraphAware on August 5, 2026, adding Hume, an intelligence-analysis platform built on Neo4j for government agencies and other organizations.

Co-founded by Emil Eifrem, Johan Svensson, and Peter Neubauer, Neo4j remains led by CEO Eifrem. Its engineering roots lie in a content-management system whose connected data required complicated SQL queries. The team replaced its relational backend with native graph storage to address the cost of recursive joins. Its Cypher query language made connected data easier to create and query; the openCypher project opened the language to adoption across multiple graph database vendors in 2015.

In 2024, the company reported more than $200 million in annual recurring revenue, double its level three years earlier, and use by 84% of Fortune 100 companies and 58% of the Fortune 500. The same announcement disclosed $50 million in capital from Noteus Partners, reaffirming a $2 billion company valuation.
