Our Story

Siren was formed during advanced Data Science research in the area of the Semantic Web.

Dr. Giovanni Tummarello and Dr. Renaud Delbru led a team of over 30 researchers in the National University of Ireland, Galway, in collaboration with Massachusetts Institute of Technology (MIT). This research focused on how to derive meaning out of data with a particular focus on search.

Siren became a product company in 2016 and has since been successfully deployed in the areas of Law Enforcement and Intelligence, Cyber Security, Fraud & Internal Threats.
