Cannes Lions 2026 was won not by the boldest ideas but by consistency. Suncorp, AXA and Renault proved sustained commitment beats noveltya lesson especially vital for modern B2B marketers.
Different sectors. Different challenges. Yet all resisted the temptation to chase the next big campaign. Instead, they stayed committed to a strategic idea, evolving it year after year to create new value.
Les Binet and Peter Field's seminal work made the commercial case for balancing short-term activation with long-term brand building. Since then, marketing luminaries like Mark Ritson have continued to argue that brands too often sacrifice enduring growth for the next quarterly win.
This year's Cannes Lions felt like an interesting reflection of that debate. Creativity was still everywhere, of course, but it often had to compete for attention. AI dominated the conversation. Every beach was sponsored by a technology or media platform. Conversations revolved around data, automation, creators and media ecosystems.
Yet beneath the noise, a different pattern emerged. What linked many of this year's biggest winners wasn't simply exceptional creativity. It was consistencyhe discipline of staying with an idea long enough for it to change customer behavior, markets and ultimately business performance.
Suncorp redefined the role of an insurer from paying claims to helping prevent them. The company won the prestigious Dan Wieden Titanium Grand Prix for Haven, the latest chapter in a five-year strategy to shift the conversation from recovery to resilience. The long-term commitment has paid off commercially: Suncorp has grown home insurance market share from 17% to 21%, become Australia's number one home insurer, increased consideration from 34% to 41% and generated an estimated A$403 million in customer lifetime value.
AXA transformed the insurance product itself. Its award-winning Three Words initiative added just three words"and domestic violence" its insurance policies, demonstrating that consistency isn't about repeating a campaign but rather about consistently acting on a brand belief.
Renault tackled the barriers to electric vehicle adoption. The consistent strategy helped move Renault from tenth to third in brand love, during a period when the country's EV market grew from around 2% to 19%.
None of these stand-outs were simply advertising campaigns. While all three operate in consumer markets, the lesson is universal. B2B marketers face the same pressure to chase the next campaign rather than build the next chapter of a long-term brand platform.
Different expressions, but all proof that consistency isn't about repeating executions: it's about staying true to a strategic platform that's rich enough to keep generating fresh ideas and measurable commercial returns.
The revenue case for consistency is clear. B2B companies with strong brands outperform weak-branded competitors by 20% in total shareholder return, according to McKinsey. Customers exposed to a consistent brand experience show 3.5 times higher loyalty. B2B decision-makers are also 10% more likely to consider brands with strong general recognition.
Yet less than 10% of B2B companies report having consistent branding. The gap between the evidence and the execution is striking.
In B2B marketing, the pressure to constantly launch new campaigns is relentless. But the data says the brands that win are those that stay the course, build trust over time, and resist the temptation to chase every shiny new tactic.
The 2026 Cannes Lions winners understood what too many B2B marketers forget: long-term brand building isn't simply about spending over the long term. It's about staying committed to an idea long enough for it to earn compound returns.
