Started in radio at fifteen. Spent 30 years helping media leaders make calls they can defend.
Operator first. Adviser second. What follows is the role-by-role, market-by-market record — for press, procurement, and anyone who wants the full picture before a first call.
Samuel Zniber. Walked into a French radio newsroom in 1985, at fifteen years old — NRJ Group, France. Moved through production, on-air work, and leadership positions fast — building a rare combination of creative instinct and operational discipline that would define everything to come.
One principle from those early years still drives the work: the best decisions in audio come from understanding both sides — what people feel, and what the numbers actually say.
Inside the world’s biggest audio companies.
Operator roles at RTL Group and Lagardère Active in France, Chrysalis in the UK, and ARN iHeartMedia in Australia. Strategic-advisor work since has covered France, Spain, Portugal, Denmark, Finland, Brazil, Canada, the United States, South Africa, and others — 30+ markets in total.
That range gives him something most advisers don’t have: a practical understanding of how audience and customer behaviour shifts by culture, platform, and moment, and how strong brands stay consistent while still evolving.
Building the tools he wished he’d had.
Today, Samuel is the Founder and CEO of MusicDatak, a France-based SaaS platform that helps radio teams figure out what listeners actually enjoy, what makes them stay, and what drives them away. MusicDatak supports stations in more than 20 countries.
In parallel, he leads MediaDatak, where his team builds pre-launch simulations that let broadcasters, podcast networks, and television providers test content, formats, and campaigns in realistic environments — before going live.
Both tools share a philosophy: test the move before you spend the money. No personal data collection. No vanity dashboards. Just honest signal about what will work and what won’t.

The career, compressed.
On-air at NRJ Group, then production, then leadership
Walked into a French radio newsroom at fifteen — NRJ Group, France. Moved through production and on-air work into programming leadership. Learned the job on the microphone side before ever writing a strategy memo.
Programming & content leadership
Music, format, and talent decisions across European and Atlantic markets. Regular speaker since at Radiodays Europe and Radiodays Asia.
Group operator roles
Senior operator at Lagardère and RTL Group in France, Chrysalis in the UK, and ARN iHeartMedia in Australia. Format rollouts, M&A integration, turnarounds, and multi-market launches — done from the inside, with a P&L on his name.
Advisory practice
Decision Sprints, 90-Day Programs, and board retainers for CEOs, chairs, and owner-operators of media businesses — France, Spain, Portugal, Denmark, Finland, Brazil, the US, Canada, Australia, South Africa. Clients stay confidential; references shared after a fit call.
Founder, MusicDatak & MediaDatak
Simulation platforms built so a Sprint decision can be tested against how real listeners and readers would respond, before the first euro of rollout is spent. Research collaboration with François Pachet (former Spotify Creator Tech Research Lab).
Executive education. International perspective.
Samuel has completed executive programs at Harvard Business School (Harvard & Bertelsmann Executive Program, one of 40 selected from Bertelsmann, owner of RTL Group and M6), Columbia Business School (Digital Marketing Strategy), HEC Paris (Managing Across Cultures), and UCLA Anderson School of Management.
A regular speaker at Radiodays Europe and Radiodays Asia, Samuel is known for turning complex data on audiences, users, and customers into plain-language strategy that teams can act on immediately.
If it doesn’t work on Monday morning, it doesn’t matter how good it looks in a slide.
20 minutes. No pitch. Bring the decision in front of you; I’ll bring the three things I’d test first.
