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.Chapters:00:00 - Welcome: Byron Sharp at Cannes, and why impact (not academic prestige) drives Ehrenberg-Bass01:39 - The “two festivals” of Cannes: creativity awards vs. the serious fringe; the sold-out Ritson session04:03 - What’s being sold to marketers on the Croisette — and the retail-media land grab (Marriott Media)05:26 - Fragmentation, monetizing inventory, and why ~80% of this year’s AI vendors will be gone07:02 -The five things Byron agreed with Ritson on10:21 - #1 Mental availability — and the critical mistake of confusing it with awareness12:27 - “You overestimate your reach”: fleeting exposures and inflated media metrics14:19 - Why calling it “search advertising” was a disservice: purchase vs. mental availability15:27 - #2 Distinctive brand assets — why a logo checkbox isn’t enough17:46 - #3 Consistency — everyone agrees, nobody does it18:50 - The “big idea,” category entry points, and the Frozen/Elsa problem21:42 - Inside the How Brands Grow executive program23:46 - “Non-artificial intelligence”: the AI agent Ehrenberg-Bass is building25:20 - Wrap

After five days, dozens of interviews, countless presentations, and conversations with some of marketing's brightest minds, one thing became clear:The future of marketing isn't about more technology. It's about better thinking.Throughout Cannes Lions 2026, we spoke with leaders from System1, WARC, Ehrenberg-Bass, Amazon Ads, Pinterest, and many of the industry's leading creative and effectiveness thinkers.In this final Cannes Cut, we reflect on the biggest themes that emerged throughout the week, including:Why simplicity continues to outperform complexityHow AI is settling into its rightful role as a tool—not a strategyThe growing danger of the efficiency trapWhy creativity remains one of the strongest commercial advantages a brand can buildThe return of long-term thinking, brand building, and strategic disciplineWe also sit down with David Tiltman (WARC) to discuss the Multiplier Effect Playbook, organisational barriers to effectiveness, why strategy is becoming more important than ever, and how marketers can bridge the gap between knowing what works and actually doing it.To close out the series, we head back onto the Croisette for one final edition of The Buzz Cut, featuring conversations with:Aaron Starkman (Rethink)Brendan Christie (Strategy Magazine)Ruxandra Papuc (AIN'T)Presented by System1.If you've enjoyed following our Cannes journey, thank you for joining us throughout the week.Chapters:00:00 - Introduction02:15 - Reflecting on an Incredible Week06:30 - Simplicity Wins11:05 - AI Finds Its Place16:10 - The Efficiency Trap21:45 - Why Brand Experience Matters26:10 - Is This the Best Time to Be a Marketer?30:30 - Interview: David Tiltman52:30 - Final Buzz Cut58:15 - Wrapping Up Cannes

Day 4 on the Croisette, and the Cannes Festival of Creativity is in full swing. The Cannes Cut series is proudly presented by System1.Vanessa Chin, VP Marketing at System1, opens with a live field dispatch: which campaigns are actually scoring at Cannes, what the new Creator Effectiveness Playbook says about briefing for emotional impact, and why Dunkin' took gold while Kit Kat posted one of the highest out-of-home scores System1 has ever recorded.She also tackles the question the industry keeps circling - is AI the creative revolution everyone promised, or just a better production tool?Then the feature interview.Orlando Wood, Chief Creative Officer at System1, argues that dull advertising is structural, not incidental.Media fragmentation, measurement frameworks calibrated for the wrong school of advertising, and rules-based creative thinking all work against artistry before a single brief is written. Drawing on advertising history from Toulouse-Lautrec to Bernbach, and neuroscience from Ian McGilchrist, Orlando maps the war between showmanship and salesmanship - and explains why applying one school's measurement philosophy to the other destroys the work.The episode closes with the Buzz Cut: the sights and sounds from the attendees. Ty Heath from LinkedIn shared her perspective on life inside the B2B Lions jury room, WARC APAC's Rica Facundo on the three ceilings of social, Hannah Riberdhal from Brand Marketing Sweden on what this year's Cannes sounds like compared to four years ago, and two Young Lions competitors fresh off a 24-hour brief.Timestamps0:00 Opening - Vanessa Chin (System1) on Cannes testing, AI, and the Creator Effectiveness Playbook12:23 Feature interview - Orlando Wood on why dull advertising is structural, not a talent problem23:06 Fluent devices, coherence vs consistency, and the living brand33:08 The history of showmanship and salesmanship - and why creators may be bringing artistry back37:11 Measuring creative: why salesmanship measurement destroys showmanship work40:10 Post Pod debrief41:18 Buzz Cut - Ty Heath (LinkedIn B2B Institute), Rica Facundo (WARC APAC), Hannah (Brand Marketing Sweden), Young LionsReferencesSystem1 https://system1group.com/Advertising Principles Explained (course with Sir John Hegarty) https://advertisingprinciplesexplained.com/System1 Creative Dividend Report https://system1group.com/the-creative-dividendSystem1 Creator Effectiveness Playbook https://system1group.com/the-creator-effectiveness-playbookLemon: How the Advertising Brain Turned Sour - Orlando Wood (book) https://system1group.com/lemonThanks for keeping us in your ears, stay sharp everyone.

Day three at Cannes Lions revealed something unexpected.Coming into the festival, many predicted AI would dominate every conversation.Instead, another topic has quietly taken centre stage:Creators.Not creator hype. Not influencer marketing. Creator effectiveness.Presented by System1, today's Cannes Cut explores one of the biggest conversations happening across the Croisette. Marc and Vassilis reflect on another packed day at Cannes, including the System1 Stars of the Show event featuring Andrew Tindall, Orlando Wood, Mark Ritson, Les Binet, Adam Morgan and many of the industry's leading thinkers.The featured interview is with Andrew Tindall, Chief Growth Officer at System1, who joins us to discuss the new Creator Effectiveness Playbook, developed in partnership with WPP and TikTok.One insight stood above the rest:Most creator campaigns aren't driving meaningful brand growth. A small "brilliant minority" are responsible for the majority of the impact.The conversation has evolved beyond follower counts and engagement rates. Instead, marketers are asking better questions:Does this creator genuinely fit the brand?How do creators build memory, not just engagement?Why does emotion still outperform optimisation?What role do distinctive brand assets play in creator content?And how do we stop treating creator marketing like a casino?We also bring back another edition of The Buzz Cut, hearing directly from marketers around the world, including Lauren Anderson (Amazon Ads), David Tiltman (WARC), Reno from Nikkei, and Vinnie from Leo São Paulo, sharing what's capturing their attention halfway through Cannes.In this episode:Highlights from System1's Stars of the ShowAndrew Tindall on the Creator Effectiveness PlaybookWhy only a small minority of creator campaigns drive real growthWhy brand fit matters more than follower countPinterest's positioning around quality engagementWhy AI feels more like infrastructure than the headline storyThe latest perspectives from marketers across the CroisetteThe rosé can wait.

This episode has been presented by System1.Everyone talks about the full funnel. Amazon has actually built it. Day 2 of the Sleeping Barber's Cannes Cut takes Marc and V from the Amazon port activation, a full marina-length brand experience housing a cafe, a speakeasy, 30 meeting rooms, and a stage headlined by Shaquille O'Neal and Oprah, to a sit-down interview with Lauren Anderson, US Head of the Brand Innovation Lab.Lauren explains what the 'canvas' framing actually means for advertisers: not a menu of placements to check, but a working-backwards discipline from brand objectives through to seamless customer handoffs. The Hellman's 'Mayo for a Melody' campaign, extending the Andy Sandberg Super Bowl spot into a Fire TV karaoke experience with QR-enabled purchase, is the clearest case study of how awareness converts to action without the usual clunky hand-off between platform teams.The conversation also covers creator partnerships (co-collaborators, not billboards), the messy middle of measurement (experiential value is real but long-horizon), and why the Brand Innovation Lab's ethos is restraint: not throwing every part of the canvas at a brief, but identifying what's most fit for purpose.Buzz Cut guests from the catamaran round out the episode: Esther Benzi (CMA President), Zach Grossman (Director of Sales, TikTok Canada), Neil Mohan of ClickHealth, and Jeanette from Hashtag Paid, all weighing in on creativity, measurement, and what it actually feels like when AI takes the backseat at Cannes.Chapters00:00 - Cannes 2025, another look05:13 - Amazon's Brand Activation at Cannes10:03 - bInsights from the Boat: Networking and Learning11:43 - Lauren Anderson and The Role of the Brand Innovation Lab19:59 - Campaigns that Connect: Hellman's and More31:36 - Esther Benzie32:52 - Zack Grossman34:26 - Neil Mohan37:17 - Jeanette Rees

This episode has been presented by System1.What happens when Byron Sharp, Mark Ritson, System1, creators, AI, and Cannes Lions all collide on Day One?In the first edition of our Cannes Cut series, presented by System1, Marc and V unpack the biggest themes emerging from Cannes Lions 2026, including why creativity is increasingly being judged through the lens of effectiveness, why marketers may be spreading budgets too thin, and why some of the industry's biggest thinkers are converging on a surprisingly small set of principles.Along the way, the guys sit down with Vanessa Chin (SVP Marketing, System1) to discuss creativity, creators, celebrities, emotional advertising, AI-generated campaigns, and why happiness and humour continue to outperform serious purpose-driven work.They also hit the Croisette to capture perspectives from attendees, founders, creators, publishers, and marketers about the trends shaping Cannes this year.In this episode:Why effectiveness has become the dominant conversation at CannesDavid Tiltman's "Fewer, Bigger, Better" frameworkThe five things Byron Sharp and Mark Ritson agree onMental availability and why awareness isn't enoughDistinctive brand assets and why logos alone don't cut itWhy sophisticated mass marketing still mattersThe case against purpose-led marketingHow creators are becoming marketing "super touchpoints"Why funny advertising continues to outperform serious advertisingThe role AI is actually playing in modern creative developmentSights and sounds from the CroisettePlus: exclusive insights from Vanessa Chin and conversations with marketers attending Cannes from around the world.The Rosé can wait.

What if the biggest problem in marketing isn't your message, your targeting, or your budget? What if it's the map you're using?For more than a century, marketers have relied on funnels, customer journeys, and pipeline stages to explain how people buy.The problem?People don't move in straight lines.In this Sharp Cut, Marc and Vassilis unpack why buying behaviour looks far more like a messy search pattern than a carefully planned journey. Drawing on research from Ehrenberg-Bass, Google, WPP, Oxford, James Hankins, Gartner, Bain, and the LinkedIn B2B Institute, they explore why most consumer decisions are made before shopping begins and why so many B2B deals stall after the buying process has already started.Along the way, they tackle the real purpose of the funnel, the limits of customer journey mapping, the hidden role of buying committees, and why the pipeline may be better at reporting decisions than helping people make them.In this episode:Why the traditional funnel continues to surviveWhat the Consumer Decision Journey got right—and wrongThe surprising finding that 84% of purchases favor brands consumers already lean towardWhy "good enough" beats "best" more often than marketers realizeThe difference between consumer and B2B buying behaviorHow buying committees create friction inside organizationsWhy 40-60% of qualified B2B deals end in no decisionThe pipeline's real purposeWhy probability may be a better model than journeysThe funnel is a useful reporting tool. It just isn't a very good theory of human behaviour.Takeaways:Success in marketing is often misrepresented as a straight line.The consumer decision journey is more complex than traditional models suggest.Buyers often choose brands they are already leaning towards before shopping.The funnel oversimplifies the buying process, leading to ineffective strategies.Fear of making the wrong decision can paralyze B2B buyers.Satisficing is a common behavior where buyers settle for 'good enough'.Mental and physical availability are crucial for influencing buyer decisions.The traditional funnel model is outdated and needs to be rethought.Understanding buyer behavior requires acknowledging the chaos of the decision-making process.Marketers should focus on building frameworks based on real consumer behavior rather than idealized models.Chapters:Chapters00:00 - Introduction02:48 - The Complexity of the Consumer Decision Journey06:06 - The Limitations of Traditional Marketing Models08:49 - Understanding Buyer Behavior and Decision-Making11:59 - Rethinking the Marketing Funnel14:57 - The Role of Fear in B2B Buying Decisions17:53 - Building a Better Marketing Framework

For years, Cannes Lions has been the home of creativity. This year, it feels like effectiveness is taking center stage.In this special Cannes preview edition of The Barber's Brief, Marc and Vassilis discuss what they're most excited to explore at Cannes Lions 2026.From the surprising reunion of Mark Ritson and Byron Sharp, to the growing influence of effectiveness research, creator marketing, AI, and measurement, this conversation explores the biggest questions facing modern marketers.The duo also shares details about their partnership with System1 and previews the conversations they'll be recording throughout the week with Orlando Wood, Andrew Tindall, Vanessa Chin, and many others.Plus, they break down one of last year's most creative Cannes winners: Hyundai's Night Fishing.In this episode:Why the Ritson & Sharp reunion mattersCan creativity still drive disproportionate growth?What happens to creativity in an AI-driven world?Are marketers measuring the wrong things?The difference between Cannes' Palais and the FringeWhat System1 is teaching marketers about effectivenessHyundai's Cannes-winning film experiment, Night FishingOh and our theme this year?

Most marketers think great creative comes from better talent. Karen Pearce made a different case.In this Post Pod discussion, Marc and Vassilis reflect on their conversation with Karen Pearce, Partner at Rethink and one of the leaders behind some of the most awarded creative work in the world.The discussion explores why creativity often dies inside organizations before it ever reaches the market, how criticism can become a cultural trap, and why the best creative teams focus on finding sparks rather than flaws.They unpack Rethink's CRAFTS framework, the importance of psychological safety, the role of strong client-agency relationships, and why great ideas should start with human truths rather than channels.If you've ever wondered why some organizations consistently produce breakthrough work while others struggle to move beyond safe ideas, this conversation is for you.In this episode:Why creativity shouldn't feel scaryThe danger of rewarding criticism over contributionHow Rethink's CRAFTS framework shapes better ideasWhy relationships matter more than process aloneThe importance of psychological safety in creative teamsWhy ideas should come before channelsThe hidden systems behind award-winning creative workChapters00:00 - Introduction01:42 - Rethinking Marketing Culture04:21 - The Role of Creativity in Marketing06:58 - The Importance of Effective Creative09:53 - Expanding Creative Horizons11:33 - The Value of Independence in Agencies13:39 - Building Strong Client Relationships16:40 - Harnessing Human Truths for Creativity19:24 - Frameworks for Creative Success22:30 The Significance of Briefs in Marketing24:46 Consistency and Success in Creative Work

Most people assume award-winning creative work is a high-wire act: brilliant, risky, and impossible to repeat. Karen Pearce of Rethink makes the opposite case. Fresh off Ad Age's 2026 Agency of the Year and ADWEEK's 2025 Independent Agency of the Year, and as the most-awarded independent agency in the world last year, Rethink keeps producing famous, business-moving work on purpose.Recorded as a Cannes Lions lead-up, this conversation gets into the machinery behind the run. Karen explains why independence lets Rethink protect creative standards instead of chasing scale, why the client's real job is finding sparks rather than poking holes, and how the CRAFTS framework gives a whole agency a shared language for what good looks like. Karen walks us through the Heinz philosophy that every ad is a product ad, the go-then-grow approach that turns big swings into low-risk reps, and why, going into Cannes, she expects a reclaiming of human craft in an AI-flooded market.The through-line: bold creative shouldn't feel scary. Build the right system and the right partnership, and the work that wins awards is the same work that drives the business.Timestamps00:00 Find the sparks, not the holes02:08 What's behind the run: independence and the receipts05:48 Why great creative shouldn't feel scary09:12 Builders vs hole-pokers: the client's real job14:27 Famous brands outperform business metrics19:17 AI, human craft, and the IKEA sleep talkers22:42 CRAFTS: a shared language for great work30:57 Heinz: every ad is a product ad36:24 Go then grow: getting your reps in44:17 Idea first: when media becomes the creativeReferencesRethink: rethinkideas.comKaren Pearce: LinkedIn https://www.linkedin.com/in/karengpearce/Rethink's Book: The Business of Creativity Referenced campaigns: IKEA “U Up” and IKEA organizer / Skittles out-of-home; Heinz “Looks Familiar” and the keystone ketchup pouch; Destination Canada; Coinbase craft-led film; Epitaph “garbage media” dumpster billboardsAnthropic “Keep Thinking” campaign for Claude, by Mother Awards context: Ad Age 2026 Agency of the Year
