Sleeping Barber - A Marketing Podcast

What if almost everything we've been taught about advertising is built on a sales model from 1904?
In this Sharp Cut, we unpack six of marketing's most persistent myths—from "digital has no waste" to "last-click attribution tells us what works"—before rebuilding a simpler, evidence-based explanation of how advertising actually works.
Rather than relying on theory, we challenge these ideas using our own careers, practical examples, and decades of marketing science from Byron Sharp, Les Binet, James Hurman, Orlando Wood and others.
In this episode
Why digital isn't actually waste-free
Why targeting isn't enough
Why advertising isn't sales
Why creative matters more than many marketers believe
Why personalization has been oversold
Why ROAS isn't telling the full story
Why advertising is better understood as planting and harvesting

If you've ever struggled to explain marketing to your CFO—or even to yourself—this episode is for you.

What if marketing's biggest challenge isn't proving its value—but explaining it? Following our conversation with James Hurman, we reflect on one of the most practical frameworks we've encountered in years: Future Demand.
Rather than revisiting every topic from the interview, this Post-Pod explores what the ideas actually mean for marketers trying to influence leadership, defend budgets, and build long-term growth inside their organizations.
In this episode:
Why "future demand" may be better language than "brand awareness"
Why leadership teams naturally prioritize demand capture
The role of marketing during recessions - Why great campaigns wear in—not out
Why dashboards often tell an incomplete story
Objective truth vs. personal truth in marketing
How evidence-based marketing becomes repeatable inside organizations

If you've already listened to our interview with James Hurman, this conversation helps connect the dots between marketing theory and day-to-day practice.
Enjoy the show!

24:20 Final Reflections on James Hurman’s Book

Advertising doesn't work by persuading people to buy. It works by creating future demand. James Hurman returns to unpack his new book: why the funnel is the wrong model, how the biggest group of buyers isn't in the market yet, why green dashboards can hide a dying brand, and how to make the case for brand spend to a CFO who only sees this year.
There are two types of demand in any market: the small group ready to buy now, and the much larger group who will come in later. Most advertising pours everything into the first group, watches the dashboards turn green, and wonders why the business numbers stay red. James Hurman returns to The Sleeping Barber to explain the fix at the heart of his new book, Future Demand.
Marc, V, and James work through the two-part funnel that replaces the old model, the myth that great companies don't advertise, why Volvo's Epic Split kept paying off for a decade, and why ads wear in rather than wear out. They get practical on the boardroom case: share of voice, the five to ten percent rule, and how to reframe brand as future cash flow for a finance team. They close on AI: the book's Pocket Advisor app, and how language models lean on brand signals when they choose what to recommend.

Byron Sharp — Professor of Marketing Science, Director of the Ehrenberg-Bass Institute at the University of Adelaide, and author of How Brands Grow — joins us at Cannes fresh off his sold-out Bassey Theatre session with Mark Ritson (a thousand people queued to get in).
We dig into the five fundamentals he and Ritson agreed on and, more usefully, where the industry keeps getting them wrong. Byron explains why mental availability is not the same as brand awareness, why “search advertising” was a branding con that confuses purchase availability with memory-building, and why your media metrics are lying to you about reach.
Along the way: the retail-media gold rush (sorry, Marriott Media), the AI hype bubble he expects to pop, why Elsa buried every other Disney princess, and the “non-artificial intelligence” agent Ehrenberg-Bass is building to stop corporate AI from breaking marketing’s laws of physics.
A masterclass in thinking clearly about what your marketing money is actually supposed to do.
