Hello, I Am Luka Duvnjak

Driven to be the reason why the world gets to experience and enjoy their favourite brands, daily.

A professional media strategist with a proven track record in the entertainment, beverages, technology, finance, medical and pharmaceutical industries.

About Me

I build brands with continuous mass media strategies that form, refresh and reinforce positive memory associations with audiences across the world.
Over the last 13 years, my career has taken me from humble beginnings as an amateur salesman in Johannesburg to a media professional in London having worked across a variety of global brands.
My current focus is developing and implementing media strategies that drive media consistency, effectiveness and brand love for global brands on a global scale.

Media Strategy

Getting your message in front of the right people at the right time is great. Making sure it drives the outcomes your business actually cares about is what really matters.

Audience Research

Everything starts with the audience. When you understand what people care about and how they consume media, your campaigns show up with relevance at the right moments.

Media Planning and Activation

From selecting the optimal media mix to negotiating placements and media buys, purposeful planning helps you meet your audience where they are.

A/B Testing

Using structured multi-cell lift experiments, I help brands test a variety of elements like audience, coverage, frequency, creative, and messaging to isolate what truly moves the needle for awareness, consideration, and intent.

Data Analysis and Reporting

Whether through concise reporting or deep-dive post-campaign analysis, I turn data into clear, actionable insight - simplifying decision-making and driving continuous improvement and long-term campaign success.
