About us

«When you lack a tool, craft it!».

IMG_2135After being a research scientist, a teacher and a software developer, I became a journalist 27 years ago as a staff member of french journals like SVM, Le Monde and Liberation. As a freelancer since 2007, I’ve worked for varied print media in Switzerland (Le Temps), France (Science & Vie, La Recherche, Alternatives Internationales, Tout Comprendre) and French-German  Arte Future. I was editor in chief of La Terre au carré, a french daily program broadcasted on France Inter public radio in 2019-2020, before I left to work again as a freelancer.

The evolution of journalism and the newspaper crisis makes everyday more essential the issue of working efficiency, whether you are a freelancer or not. That’s why, after having designed a journalist-dedicated word processor in 2003, I started to create the mobility tools that were missing.

After 33 months of nightly development, and intensive tests in my daily work, I am very proud to present my  first applications: Qwaz Audio for iPhone and Qwaz Pro for iPad will seduce journalists and many other professionals. These two softwares will continuously evolve, with one catchphrase: work more efficiently and write better!
