DeltaStream

DeltaStream is a real-time stream processing platform that includes streaming analytics and database features. Put simply, it is about storing and querying application data reliably.

Who is it for? Mostly developers and data teams. They also list Database, so expect those to show up in the feature set. They are a small team, 11 to 50 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

DeltaStream is based in San Mateo, California. More on deltastream.io.

Things worth asking about: managed options, backups, and scaling costs. Ask for a trial on your own data, not a canned demo.
