Senior Consultant - Transformation

AION Consulting is the Liberated Company in strategy consulting.

AION Consulting is a dynamic, independent strategy advisory group, operating through offices in Brussels, Paris, Luxembourg, Lyon, and Nantes. We specialise in strategy and operational consulting, serving startups, large companies and SMEs. We help these organisations enhance their operational strategies, processes, and performance through tailored consulting services.

Our expertise spans key industries, including Energy, Pharmaceuticals, Digital, Institutions, and Financial Services.

At AION Consulting, we believe in new ways of working based on decentralised management in which responsibilities and decision-making powers are distributed throughout self-organising teams rather than being vested in a classic management hierarchy.
