ArangoDB

ArangoDB is an open-source database that offers a flexible data model for documents, graphs, and key values. The job it does: storing and querying application data reliably.

It makes the most sense for developers and data teams. They also list Big Data, Database and Open Source, so expect those to show up in the feature set. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

ArangoDB is based in San Mateo, California. Their site is arangodb.com.

Before you commit, look at managed options, backups, and scaling costs. A short pilot with your real data tells you more than any demo.
