  23. 23. "Neo4j continues to dominate the graph database market.” “69% of enterprises have, or are planning to implement graphs over next 12 months” October, 2017 “The most widely stated reason in the survey for selecting Neo4j was to drive innovation” February, 2018 Critical Capabilities for DBMA “In fact, the rapid rise of Neo4j and other graph technologies may signal that data connectedness is indeed a separate paradigm from the model consolidation happening across the rest of the NoSQL landscape.” March, 2018 Analysts See Unique Benefits of Graphs "Neo4j is the clear market leader in the graph space. It has the most users, it uses a widely adopted language that is much easier than Gremlin and in many respects, it has consistently been a lot more innovative than its competitors.” “It is the Oracle or SQL Server of the graph database world.” March, 2019 "Our research suggests that graph databases have the best chance to survive and thrive as a distinct category (versus the other NoSQL models) because connected data applications present serious performance problems that only a specialized graph DB can solve.” March, 2019
