Quantone uses technology derived from intelligence gathering services to allow for deeply connected data, storing information on not only artists and their recorded works, but also the relationships between them.

In 2015 Quantone added music recommendations to their product range, announcing a collaboration with IBM's cognitive computing platform, Watson.

A musicologist by training, Stein worked as a programmer for the New York County District Attorney’s office, designing intelligence-gathering systems for law enforcement.
