Johan Longueville

Co-founder & partner

Born in Bruges, the loveliest town in the western hemisphere and supporter of Blauw-Zwart, the best football club in Belgium.

At the start of his carreer, Johan works as an audiologist in the hospital St.Rembert in Torhout, but soon joins the farmaceutical world, where he fills a vacancy as a hospital representative at Farmitalia Carlo Erba. The small Italian company develops anthracyclines, the cornerstone of cancer treatment for many years. Johan will always stay in oncology, although other, bigger companies continuously buy the company … Last one: Pfizer! With all kinds of functions over all these years: sales, marketing, even some European experiences …

In 2013, Johan starts a new career as an independent consultant in oncology at Astellas, where gets the responsibility to successfully build an oncology team from scratch to launch enzalutamide in prostate cancer. Great years.

Six years later, in 2019, a new opportunity knocks on the door: Johan becomes chief editor of the Belgian Oncology and Hematology News, the most-read Belgian journal in that domain. This function extends when Corona has a major influence on medical communication. Webinars, virtual congresses, and digital congress reporting altered the world of live congress and meeting attendance and print reporting.

In 2022, Johan finds some friends with the same ideas on medical communication. And of course Media Arena, a new studio, ready to organise top quality hybrid meetings. Why not start a new company? Setting new standards? Staying young? Let's go for it. Here is MediMix.

When not working, it's quizzing time. For 15 years, Johan is the captain of one of the top teams in the Flamish quiz landscape: Les Têtes Brullées.

And, of course, Johan is very proud of his two daughters. Even more proud of his two granddaughters. So please don't call him on a Wednesday afternoon.

Christophe Vandenbussche

Co-founder & partner

Bitten by sound and image, and in particular by the power of video to not only tell stories, but also show them, Christophe began his studies of Journalism at the Hogeschool West-Vlaanderen in 1998. And because practice is the best school of learning, he started working as a freelance journalist at the regional television station WTV in 1999, parallel to his studies. It was during this period that he interviewed Iron Lady Margaret Thatcher, among others. 

After graduation, the hunger for stronger technical knowledge grew bigger and bigger. And at Avid Belux, Christophe was given the opportunity, as a rookie in the world of editing, to get to know the Belgian landscape of production companies and television stations. And, of course, to drastically increase his editing skills. 

This resulted in a collaboration with Concentra Media in 2004. With the relaunch of the regional television channel Kanaal 3, a technical profile was required to run the channel operationally. But at the same time, this profile had to be able to implement a new way of making news: the video journalist. A one-man crew that interviews, films and edits. Even the BBC came to Dendermonde to see how it was done.

In 2005 the need arose within the Concentra Group for an Antwerp branch of the in-house production house Havana. Christophe decided to head the branch and built a team responsible for various programs and corporate productions. 

And in the middle of 2006 the time came: Christophe takes the step of starting his own production company: The Video Factory. Based on the principle of the video journalist. Regional television and corporate productions will remain the core business for the first few years.

In 2011, a collaboration with Mevipro is established. It is Christophe's first encounter with the medical and pharmaceutical world. It is the beginning of countless foreign congress visits and numerous productions with medical content. In 2018, Christophe continues this way of working in a new partnership: Roularta HealthCare. And in the meantime, other organizations in the healthcare sector have become regular customers. 

In 2019, The Video Factory gets a rebranding and becomes Cmore. Future-proof, with an updated strategy. Untill ... the corona virus. A game changer. Thanks to his technical knowledge, Christophe knows how to quickly switch to anything related to virtual meetings. In 2020, 2021 and 2022 Cmore conducts more than 1,200 virtual and hybrid events.

With that experience, and a firm belief that hybrid meetings are the future, Christophe is writing the blueprint for Media Arena. And during the summer of 2022, Media Arena becomes a reality. 

In the second half of 2022, circumstances ensure that three people are aligned when it comes to communication in the medical field. It is the birth of MediMix. One face, one clear proposition, and above all: a clear commitment to the customer. And for that commitment, Christophe is happy to stand by, day and night.
