Why Mavence?

"With more than 10 years of experience in government relations, from philanthropy to the private sector, I am convinced that choosing the person who will be able to embody your public affairs in the complex political and regulatory ecosystem makes all the difference when it comes to being heard and to creating effective alliances."

Corporate diplomacy and influence both require a sharp knowledge of stakeholders and a true understanding of what is at stake, experience that Thomas Grandmougin has built for himself within various organisations and working environments.

Successively responsible for public affairs in a trade association in Brussels and then in an NGO, he moved to a Top 10 Public Affairs firm in Paris before joining a large agrifood multinational and going on to lead a foundation for sustainable agriculture. In multiple roles and diverse portfolios, he has had the chance to work across various cultures and styles and to understand various strategies as well as honing the human skills necessary to lead and implement them.
