Neo4j
Neo4j is a Graph Databases company founded in 2007 and based in San Mateo, United States. It has raised $630M in total funding, most recently a Growth in 2024 at a $2B valuation.
Neo4j is the company that created the graph database category, formally founded in 2007 in Malmö, Sweden (CEO Emil Eifrem sketched the property graph model on a flight to Mumbai in 2000) and headquartered in San Mateo, California since 2011. Its native graph engine stores relationships as first-class citizens, and its Cypher query language became the foundation of GQL, the first new ISO database-language standard since SQL, ratified in 2024. The company holds roughly 44% of the graph DBMS market and counts 84% of the Fortune 100 as users, surpassed $200M in annual recurring revenue in November 2024 after doubling ARR in three years, and says it is tracking toward positive cash flow. It raised a $390M Series F in 2021 — then the largest private database investment ever — at a valuation above $2B, reaffirmed by a $50M Noteus Partners investment in November 2024, and is widely viewed as a Nasdaq IPO candidate whenever the window opens. Generative AI has become its strongest tailwind, with cloud revenue up fivefold in three years as enterprises adopt knowledge graphs and GraphRAG to ground LLMs in explainable, connected context. In June 2026 Neo4j moved up the stack, agreeing to acquire intelligence-analysis vendor GraphAware (maker of the Hume platform, built on Neo4j) to launch a government-focused alternative to Palantir Gotham, with the deal expected to close in Q3 2026 pending regulatory approval.
Neo4j invented and still leads the graph database category, and the AI wave has made it strategic infrastructure: knowledge graphs and GraphRAG are the emerging answer to LLM hallucination, and with a 44% market share, the Cypher-derived ISO GQL standard, and 84% of the Fortune 100 on its platform, Neo4j is the default graph layer of the new data stack.
