KeyCrime is an innovative startup with a strong social impact, operating in the public safety domain. It helps Law Enforcement Agencies to Digitally Transform their Investigation Lifecycle through the advanced Data Acquisition methods and sophisticated "predictive crime analysis" algorithms that make up the KeyCrime delia(r) Suite. Founded by Mario Venturi after a long experience in the Italian State Police and currently the company's President, KeyCrime aims to support police forces around the world in guaranteeing order and security in the cities we live. For this purpose, KeyCrime has developed and made available the delia(R) Suite (acronym of “dynamic evolving learning integrated algorytm”), a crime analysis’ software that, thanks to the interaction between human and artificial intelligence, is able to support police officers in the processes of "conclusive reasoning" and "decison making", in order to implement specific actions of prevention and law enforcement. delia is the most advanced crime analysis software in the world today. It does not base its analytical philosophy on mathematics nor on statistics, but on the typical investigative approach of officers, whose effectiveness is implemented through exper systems, artificial intelligence and machine learning techniques and technologies which exponentially increase its efficiency. delia(R)’s field trial has been effected by the Italian State Police in the city of Milan to fight robberies, with significant outcomes and positive effects for both the citizens and Police Officers of Milan. These results have been validated by an independent body, the Faculty of Economics at Essex University, and by the National Bureau of Economic Research in Boston.
