Nadine Gouba

HEAD OF AI & NEW TECHNOLOGIES PRACTICE

For 20 years, Nadine has supported executive teams and business lines in designing and leading major transformations. Her career, at the crossroads of business and technology, enables her to turn a strategic ambition into concrete change and to bring teams along in delivering it.
Involved early on in AI-driven transformation, she led, for a leading legal publisher, the design of the offering and the French market launch of a legal AI platform for legal and finance professionals. She ran this programme by bringing business, technology and data expertise together.
Beyond the launch, she supported the publisher's clients, notably corporate secretariats, legal departments and HR departments, in grasping what AI makes possible, identifying value-creating uses and assessing what they meant for their roles, practices and processes.
Today she continues this work with organisations that want to anticipate how AI will transform their professions and turn its potential into concrete, measurable results.
Her conviction: AI creates lasting value when it starts from business needs, changes practices in concrete ways and gives teams the means to take full part in the change.
