What Will Marketing Look Like in 2030? Top CMOs Say: Think Bigger, Build Faster, Let Go More Often

If the next decade of marketing could be distilled into one principle, it might be this: Brands are no longer just built by marketers, they’re co-authored by communities. At SXSW London, three marketing heavyweights unpacked the strategies they’re using today to prepare for 2030: AI-enhanced creativity, end-to-end brand immersion, and the rise of creator-led innovation.

Cristina Diezhandino (CMO, Diageo), Leandro Barreto (CMO, Beauty & Wellbeing, Unilever), and Rosemarie Ryan (CEO, co:collective) offered more than trends. They delivered a blueprint.

1. AI Is Not a Side Tool. It’s the Engine

Cristina Diezhandino made clear that Diageo isn’t dabbling in AI, it’s building with it. The company’s Virtual Studio has transformed how they produce content across global markets. Need 500 localized versions of a campaign for 30 countries? Done. Faster, cheaper, and more tailored than traditional production models.

But AI isn’t just for speed. At Unilever, Leandro Barreto described AI tools that now identify which ingredients drive positive sentiment in consumer reviews, then map those ingredients to proprietary formulations. This dramatically shortens R&D cycles and surfaces unexpected product innovations. In beauty, that means launching new fragrances in days, not years.

Barreto also highlighted AI’s power in decoding emotional responses to packaging, not just what looks good, but what sparks serotonin or oxytocin.

2. Influence Now Starts with the Community Not the Brand

Influencer marketing is no longer about endorsements. It’s about ecosystems. Cristina shared how Guinness has built a genuine fandom, even using AI to create viral content like the “singing pint.” Each piece is rooted in community behavior, not dictated by the brand.

Barreto took it further: “The brand doesn’t belong to us anymore. It belongs to the people who love it.” That’s not just philosophy, it’s product strategy. At Unilever, some creators are now co-designing SKUs. Vaseline, a 150-year-old brand, is shaped by how users remix it in culture from skincare to DIY hacks.

The future of influence? A bifurcation. On one side: creators as co-founders, helping to design and market new products. On the other: nano-distributors, using AI to drive reach and relevance at scale.

3. Social-First Means Business-First

Both CMOs emphasized that marketing transformation must be organization-wide. “You can’t just shift to social-first thinking in marketing if your HR, finance, or supply chain don’t evolve too,” Barreto said.

At Unilever, that meant rethinking how teams plan demand. Social virality can make a product sell out in hours. A supply chain designed for slow-moving economies of scale needs to be rebuilt for agility. Their Youth Academy initiative now educates the full business, not just marketing, on how to operate in this new environment.

4. Brand Experience Must Be End-to-End and Human

Cristina highlighted Diageo’s focus on brand immersion as a lever for loyalty and R&D. At the Johnnie Walker brand home in Edinburgh, visitors answer preference questions to receive a personalized tasting experience, backed by data that later informs product development.

She also noted the rise of cross-functional brand ownership. At Diageo, every one of the company’s 30,000 employees is considered a brand ambassador and that cultural pride turns into advocacy, internal alignment, and external equity.

5. Let Go to Get Ahead

The thread running through the session? Marketers must let go of control to create relevance.

Whether it’s creators shaping SKUs, fans reinterpreting brand meaning, or AI redefining how content is made, the marketers who thrive in 2030 will be those who build frameworks, not fixed narratives.

Barreto closed with this: “If you’re not on the front lines of community, reading comments, being in culture, you’re already behind.”
