Powerful brands grow through the ideas communities choose to share

Published:

In today’s world of infinite content and algorithmic distribution, brands grow by creating ideas communities choose to pass on. At Cannes Lions 2026, Unilever’s Chief Marketing Officer Leandro Barreto explores the new frontier of demand generation.

Long before platforms and algorithms, people gathered around fires and told stories. The ones that lasted were those that travelled. From one person to another. From a single voice to many.

While meaning still moves through what people choose to pass on, everything else has changed. We now have infinite content, endless creation, instant distribution. Volume has replaced value.

As an industry, we’ve forgotten to ask the most fundamental question: what’s actually worth passing on?

At Unilever, we’ve stopped asking what our brands want to say. And started asking who would care enough to carry it. And that changes everything.

Rethinking how we create demand

This isn’t about channels. Or media budgets. It’s about how demand gets created.

People trust recommendations from friends, neighbours, communities. That’s how it’s always been. Long before social media, influencers and algorithms.

For Unilever, it’s not about being social-first. It’s about being reality-first. But that only works when done with clear and consistent brand meaning, a commitment to co-creation and a system designed to allow ideas to scale and spread.

Take Dove’s Campaign for Real Beauty. Since we created it in 2004, the world kept changing. Social media exploded, beauty standards shifted, culture moved.

People expected Dove to move with these shifts. Not because we told them to: because they cared. The meaning of Real Beauty was so clear, they felt it belonged to them too.

A brand’s community is as important as its marketing team

That’s where things get interesting for us as marketers. Not in terms of what we say, but what people choose to do with it.

Dove partnered with Reddit, inviting unfiltered reviews of its Intensive Repair 10-in-1 Serum Hair Mask and committing to publish the first 50, with permission, whether positive or negative, without edits. Sales surged by over 100% on the previous year. The product became the No.1 bestselling hair mask in the US during the campaign. And r/eal Reviews racked up more than a billion earned impressions.

It’s Dove’s community – not its marketing team – who decide what gets carried. And that’s the challenge. Can we, as marketers, get out of our own way?

When people stop reshaping your brand, it’s stopped mattering

For a hundred years, we thought we knew what Vaseline was: a skincare brand. But when we started looking and listening, we discovered uses we’d never intended or imagined.

The brand invited communities to share their hacks, and our scientists tested and verified the ones that worked.

The community were not diluting the brand. They were expanding its meaning. Into worlds where we never knew it belonged.

We kept going, giving them even more power. We identified the originators behind the most popular hacks, then co-created new products with them. Transforming community creativity into an innovation engine.

The result: double‑digit growth for Vaseline over three consecutive years.

Various products in the Vaseline Originals range, which the brand co-created with originators of the most popular viral hacks.

Unilever sees creators as collaborators, not channels

This is a shift from transactional influence to building platforms where creators and communities actively shape the brand.

When NFL quarterback Will Levis started adding Hellmann’s mayo to his coffee on social media, the internet lost its mind. We asked ourselves: what is he telling us about who we are? We formed a partnership and made headlines with the world’s first mayonnaise-inspired fragrance. Will Levis No.8 sold out in under a minute and generated over 10 billion impressions online.

Our global laundry platform Dirt Is Good (DIG) is another example of co-authoring. Working with Arsenal Women since 2023, the partnership has flexed into new territories as new insights were uncovered from the community – from period stigma to the gender participation gap. By staying true to DIG’s meaning as a force for confidence and resilience, it was able to enter cultural spaces and add value to the community.

And it works. Persil has seen a 13% year-on-year increase in usage among those aware of the partnership and 6% growth among rival fans.

Desire at Scale anchors our broader business transformation

This isn’t a philosophy. It’s an operating model.

And it’s fundamental to how we’re delivering Desire at Scale by elevating the quality, relevance and reach of our brands, supported by investment and technology.

We’ve increased investment behind our brands by around 300 basis points in the last three years. Today it’s around 15% of turnover – our highest level in over a decade – across brand building, retail and omni-channel activation to ensure our brands win wherever consumers shop.

We’re deploying advanced tools to respond faster, personalise at scale and continuously optimise performance. Through digital twins, we’re producing product imagery at twice the speed and half the cost, and AI Studios are delivering content 30% faster while doubling click‑through rates.

Marketing powers Desire at Scale – turning creativity, relevance and execution into sustained growth. This was reflected in our Q1 2026 results. Strong momentum was led by our Power Brands, which grew underlying sales by 5%, with volumes up 4%.

Messages and meaning that travel

Desire at Scale requires poetry and plumbing. Poetry creates meaning. Plumbing is the systems, tools and technology that make a story scale. Without poetry, nothing matters. Without plumbing, nothing spreads.

When I think about building brands, I think about messages and meaning that travel. Real Beauty, Vaseline Verified – these aren’t campaigns, they’re fires. And creators are our torch bearers.

If nobody’s carrying your fire anymore, you don’t have a media or a creator problem. It means people don’t want to share it. And no media plan will fix that.

Marketing today is about building something worth repeating. And building trust so that people want to pass it on.

Frequently asked questions

  • What is Desire at Scale?

    In 2025, Unilever launched Desire at Scale as the anchor for our broader business transformation. At its core is a fundamental shift in how we are elevating the quality, relevance and the reach of our brands. It is the single biggest driver of volume growth rates of our Power Brands. Desire at Scale is about brands that are rooted in superior science with best-in-class aesthetics, visibility and sensorials. Brands that are talked about, recommended by many to many, and that are culturally relevant.

  • How is Unilever using AI to boost demand generation?

    AI is a key enabler of this shift in how demand is generated. The advantage lies in how it is applied. Our focus is on how AI amplifies creativity, sharpens execution and powers social-first, creator-led marketing at scale. Our edge comes from combining AI with superior brands, deep cultural understanding and creator partnerships – enabling us to create demand in ways that are distinctive, scalable and hard for our competitors to replicate.

  • What is Unilever’s approach to brand building in partnership with creators?

    We have significantly expanded the scale of our creator ecosystem, embedding creators as co-authors of our brands, not simply channels of distribution. Our approach is grounded in the reality of where trust, influence and real conversations happen. By placing culture, creators and communities at the centre of how our brands show up, we generate stronger social validation, faster demand creation and more relevance in the moments that matter. Results are showing that when brands earn social validation, cultural relevance converts directly into sales.
