Quantum4D

Quantum4D offers a visual information solution for the identification of trends, relationships, and anomalies in large real-time data. The job it does: building software for you when nothing off the shelf fits.

Who is it for? Mostly companies with a specific process to automate. 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.

Quantum4D is based in San Francisco, California. You can read more at quantum4d.com.

If you have worked with Quantum4D, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
