Neo4j – Open Source, Big Community
The development efforts on Neo4j began in 2000, when the co-founders, while on a project, encountered a graph problem that couldn’t be solved with relational databases. For the next 10 years, they continued developing and deploying Neo4j at various other organizations with similar requirements.
Finally in 2010, they decided to launch Neo4j version 1.0 as an open source graph database. Since then, Neo4j has quickly risen to become the most popular graph database in the world as rated by DB-Engines and by hundreds of thousands of Neo4j community members.
The Neo4j development team continued to enhance the product and reached another milestone with the release of Neo4j 2.0 in December 2013. Since its inception, Neo4j has been adopted globally by thousands of organizations ranging from startups to Fortune 500 companies.
