Neo Technology develops Neo4j, a Java-based open source NoSQL graph database that has been instrumental in bringing the power of the social graph to customers such as Adobe, Cisco, and Deutsche Telekom. Neo4j is useful in searching social network data and establishing connections between data. It is useful for problems that require repeated network probing as the database uses nodes to store information, which is then linked. Neo4j has a broad ecosystem of partners and tens of thousands of successful deployments. It was listed as a Niche Player in Operational Database Management Systems by Gartner in 2014.
