About us


In Extenso Tourism, Culture and Hospitality is the consulting arm of the In Extenso group, one of the leading chartered accountants in France.

Our department employs 20 full-time consultants in Paris, Bordeaux, Nantes, Cannes and Caen.

Specialised in the areas of tourism, culture and hospitality, our team provides public and private industry players in France and abroad with strategic consulting services and project roll-out assistance.

Our consultants’ expertise deals specifically with each area (Culture, Tourism, Hospitality). However, we value the interchange between each, so that every project and client can benefit from the sum of our competencies.

Because each project is unique, IE TCH puts together customised, multidisciplinary teams comprising regular, specialised partners : architects, landscapers, scenographers, museographers, lawyers, urban planners, economists, engineering and design firms, along with experts in live shows, contemporary art, the Arts, sustainable development, river and maritime tourism, mountain sports, nature activities, lodging, leisure and sports facilities, etc.

Assembling these various skills is a strategic challenge which enables us to propose operational assistance founded on highly specific expertise in very particular areas.
