5 lessons from Cannes on staying close to your audience

For years, marketers have talked about being consumer-centric. But if Cannes Lions 2026 revealed anything, it's that consumer closeness is a true competitive advantage.

Across sessions from P&G, Unilever, Levi's, Kraft Heinz, Taco Bell, KFC and more, a consistent theme emerged: the brands winning today aren't simply researching consumers. They're listening to them, learning from them and building alongside them.

Here are five lessons from this year’s Cannes Lions on what it takes to stay close to consumers today.

TL;DR: 

1. Remember: the consumer is still the boss

2. Communities matter more than audiences

3. Social listening is becoming a strategic advantage

4. Culture is the context behind consumer behavior

5. The future belongs to brands that build with consumers, not for them

In a week filled with conversations about AI and cultural relevance, one message remained remarkably simple.

As P&G’s Chief Analytics & Insights Officer Kirti Singh put it: 

"The consumer remains boss."

While technology continues to transform how brands reach people, the fundamentals haven't changed. The most effective marketing starts with understanding what consumers need, value and care about.

Several speakers reinforced this point. Mastercard's CMO spoke about moving beyond awareness to understand the role the brand plays in consumers' lives. Kimberly-Clark’s Chief Creative & Design Officer highlighted how shifting from product-focused messaging to understanding the emotional realities of parenthood unlocked stronger connections with their consumers.

Takeaway: Technology may change, but consumer understanding remains the foundation of growth.

One of the most notable shifts at Cannes was the language marketers used to describe the people they serve.

Brands are moving away from thinking about audiences and more toward thinking about communities.

Unilever's CMO Leandro Barreto reminded attendees that people have always trusted their communities more than brands. 

"We stopped asking what our brands want to say — and started asking what others want to say about our brands. And that changed everything."

- Leandro Barreto, CMO, Unilever

He argued that marketers should stop asking what they want to say about their brand and start asking what people want to say about it.

The same theme surfaced across sessions from Heineken, Walmart and e.l.f. Beauty. Whether discussing fan culture, creators or online communities, speakers consistently highlighted the importance of participation over interruption.

Takeaway: The strongest brands are finding ways to become part of the stories consumers are already telling.

Several speakers also described social listening not as a marketing tactic, but as a strategic advantage.

KFC Thailand's CMO argued that some of the best briefs have come directly from their social media teams. Coca-Cola's CMO panel identified social listening as one of the most underutilized sources of insight available to marketers today.

And the most compelling examples shared during the week didn't start with campaign briefs. They started with observed comments, complaints, behaviors and conversations.

All of this points to social listening increasingly serving as an early warning system, trend detector and innovation engine all at once.

Takeaway: The brands that listen closely where consumers interact are often the first to spot emerging opportunities.

One of the most thought-provoking sessions came from Levi's CMO Kenny Mitchell and marketing professor Marcus Collins.

"There is no external force more influential on human behavior than culture, full stop."

- Kenny Mitchell, CMO, Levi’s

Their argument was straightforward: if marketing is ultimately about influencing behavior, then understanding culture is essential because culture is one of the strongest forces shaping behavior.

Levi's approach reflects this philosophy. The brand invests not only in major cultural moments but also in emerging communities and subcultures that could shape mainstream culture in the future.

This idea challenges marketers to think differently about consumer insights. Instead of only asking what consumers want today, brands should also ask which communities, values and cultural movements are shaping what consumers will want tomorrow.

Takeaway: Understanding culture isn't separate from understanding consumers. It's often the same thing.

Perhaps the strongest lesson from Cannes was that consumer closeness increasingly requires co-creation.

Unilever shared how Vaseline discovered hundreds of unexpected uses created by consumers. Instead of resisting them, the brand embraced them. What initially looked like off-brand behavior became a source of innovation and growth.

Across sessions, marketers repeatedly emphasized listening and participation, indicating that the role of the brand is becoming less about controlling the narrative and more about enabling consumers to shape it.

Takeaway: The most successful brands will be those willing to listen first and speak second.

If there was one overarching message from Cannes Lions 2026, it was that consumer closeness is no longer just the responsibility of the insights team — it’s becoming part of the overall growth strategy.

The brands making the biggest impact are working towards building stronger relationships with consumers by paying attention to culture, listening to communities and responding to real human behavior.

So even though we’re in an era that’s seemingly defined by AI and automation, the competitive advantage may actually be surprisingly human: staying genuinely connected to the people you serve.
