Portrait de Yasmine Maachi

Yasmine is working hard on her bio. Meanwhile here is some lorem ipsum: ulla vitae elit libero, a pharetra augue. Aenean lacinia bibendum nulla sed consectetur. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Maecenas faucibus mollis interdum.

François Defossez

Chief Consulting Officer

Chief Consulting Officer

Portrait de François Defossez

Distributing Adobe and Apple throughout Africa and the french overseas territories is great, but in the end François got tired of lying on the beach, and ended up missing Paris's periphique (motorway). So he moved on to to PubliAtis, creating SaaS CMS systems to develop the distribution of the press in France. In 2011, Francois launched himself as an entrepreneur when he created the website ArtyWalrus.com, which he sold in 2013.

Head of Tunisia Office

Portrait de Arij Housseini

With over 10 years of Executive and Management experiences, Arij is both a THINKER and a DOER in all the digital marketing and IT projects she handles. First at Nextedia (SEO & Search Manager) then at Digital Developers (Digital Strategy Key Account Manager), she has proved her dual technical and marketing skills. In 2015, she joined CosaVostra as Head of the Tunisia Office.

Ines Berbeche

Chef de projet

Chef de projet

Portrait de Ines Berbeche

Hired by chance (yes it is possible), Ines is a rather unusual hybrid. After almost a year of working together, no one could give you the exact title of her position (in the best possible sense). Project management, content writing, Marketing, Design or even administrative and HR– she never refuses a mission. It is enough to ask her ''kindly''. Her touchstones: intellectual curiosity and continuous learning.
