Jean-Christophe LAISSY


At Veolia since 2015 as SVP, Global Chief Information Officer, in charge of enbaling the Digital Transformation for the Group, I report to the COO, being member of the Veolia Management Board.

My Business School qualification, combined with strong Digital skills, enable me to lead and steer large, international and complex organizations, always focused on business alignment, customer service and quality. After 25 years working in IT & Digital department for Fortune 500 companies, such as ArcelorMittal, Renault-Nissan, Thales, Alstom and now Veolia, I am very aware about what is at stake about Digital Transformation. I am convinced that IT department is now one of the business of a compagny and cannot be considered anymore as just another support function. This is currently the major shift we have to face and Big Data Analytics is the answer to tackle those challenges.

I began my career in 1993 at ArcelorMittal where I held various responsibilities over a 7 year period, among which was a 3 year stint in Barcelona in the commercial subsidiary UGINE Iberica. Then, I joined Renault in 2000, running the intranet/Business to Employee program, being head of the CIO Office in charge of communication, marketing and relationship with Nissan, and at last VP IT Group infrastructures & operations. In 2009 at Thales, I was appointed as Group CTO, before joining Alstom in 2012 as Deputy Group CIO.
