Julia and André sit together with Tim Ceuppens, CMO of the Belgian brand Pit&Pit, to uncover the surprising truth about why most data presentations fail.

In this episode, Tim shares how he turned boring, ineffective reporting meetings into compelling business discussions - by transforming the way we tell stories with data. From Pixar story structures to Jurassic Park analogies and real-life corporate lessons, Tim delivers an insightful, entertaining, and incredibly practical masterclass on data storytelling.

You’ll also learn how cognitive biases hijack our dashboards, why too many numbers destroy clarity, and how to present results in a way that actually drives decisions. And yes, you’ll never watch a Pixar movie the same way again.

But what makes her stand out is her radical view of experimentation as a truth-seeking mechanism - one that can disrupt hierarchies, challenge egos, and even drive change in toxic company cultures.

Key Highlights:

• Lucia’s first experiment at age 11: selling clay bracelets online

• Why she left journalism for CRO - and how both seek truth

• How introverts can leverage data to amplify their voice at work

• The concept of “Collaboration Bonus” and how diverse teams outperform
