Guest Factor offers consulting & interim management in marketing and sales for hospitality and leisure brands.

High-tech communication with integration of new marketing tools as well as high touch service / experience form the basis of a method in which the guest plays the key role. This way companies and their guests are brought closer together.

My know-how of industry contacts and know-how inner working help to give a front-row seat to understand business.

Together we take on the challenge to realize business growth by identifying, creating and delivering customer value.


For this purpose, the need-oriented business and marketing model 'Relationship truths' by hotelier Chip Conley is used. This model helps to make the most of the true potential of all stakeholders, creating brand loyalty and long-term relationships.

My broad expertise and insight from the hotel and entertainment industry in Belgium and abroad guarantee the development and implementation of an effective and sustainable strategy based on the company culture. 


Guests become brand ambassadors and you welcome guests that make you happy.
