The Corlytics team is a unique combination of legal and regulatory experts, proven securities and risk practitioners, leading data scientists and seasoned technologists

John Byrne is founder and CEO of Corlytics, responsible for setting the company’s vision and strategy.

He is a serial entrepreneur in the financial technology sector, John has built and sold a number of global technology based enterprises. He co-founded one of the first campus companies in Ireland in 1985 in the energy technology sector and built Information Mosaic in 1997, a global player in the securities software industry which was sold to Markit in 2015.

Corlytics was formed in 2013 and today is the global leader in regulatory risk intelligence.
