Neo4j, Inc. is a global graph intelligence company that provides technology for analyzing and managing connected data.

It is most known for creating the Neo4j Graph database, a graph database management system (GDBMS), which is implemented in Java and accessible from software written in other languages using the Cypher query language through a transactional HTTP endpoint, or through the binary "Bolt" protocol.

The company contributed to the development of the Graph Query Language (GQL), an ISO-standardized query language for property graphs, and is a founding member of the GraphQL Foundation, an open-source initiative under the Linux Foundation.

Graph database management systems, such as the Neo4j Graph Database, are used in artificial intelligence applications to represent and query relationships within connected data.

As of 2024, the company was valued at $2.2 billion with over 800 employees and 1,700 customers globally, with deployments across financial institutions, government, retailers, and technology companies. Neo4j has over 300 enterprise customers, including Adobe, Microsoft, Walmart, UBS, and Daimler Truck.
