Séverine Duprat


After completing my Master in Journalism and Communication at Université Libre de Bruxelles,

I undertook communication roles for a number of high-tech companies. I also worked as a journalist and PR consultant. Following a two-year stint in a design agency, I went on to found my own agency, Bliss Communication, in 2005. In 2011, I decided to join forces with Upgrade, an agency owned by Jacques Ost, to form double-id. I split my working time between Brussels and Montpellier. I have a genuine passion for communication, specialising in corporate culture and inbound marketing.

Jacques Ost


After completing a Master's degree in economics (Brussels), I began my career as a business development officer in the graphic arts and

printing sector. I managed several key accounts and advertising agencies until 1990, when I was appointed as Managing Director of a photo-engraving company that specialised in art books

and high-end photo retouching. I founded Upgrade in 1995 and spent the next 15 years growing the business from a production office to a full-service communication agency. In 2011, I joined forces with Séverine Duprat to found double-id.
