How AI is reshaping identity and marketing: Insights from Cannes Lions 2025

Published: October 29, 2025 by Experian Marketing Services

At A Glance

Marketers are using AI to better understand audiences, improve efficiency, and build privacy-first identity solutions. At Cannes Lions 2025, leaders shared how AI and structured data help deliver relevant messages, adapt to consumer needs, and build trust. Experian supports this through ethical efforts and innovative solutions.

Artificial intelligence (AI) is becoming a bigger part of modern advertising, changing how brands connect with people. At Experian, we believe this technology should make marketing more human, not less. We use AI to help marketers understand consumer behavior, respect privacy, and deliver messages that matter.

As part of our latest Cannes Content Studio series, we spoke with leaders from AdRoll, MiQ, OpenX, Optable, PMG, PubMatic, and Yieldmo. Their insights show a clear path forward; one where technology supports human strategy to create more meaningful connections.

1. How does AI help you see audiences more clearly?

How does AI help you see audiences more clearly?

AI decodes complex behavioral signals to reveal the values and mindsets behind decisions, and increasingly, it predicts what audiences will care about next. This allows marketers to deliver timely, relevant messages that resonate with audiences. At Experian, we help brands use these insights to connect more meaningfully and ethically.

Takeaway: Experian’s tools help brands uncover audience insights, enabling more meaningful and ethical connections.

2. Where does AI actually save time, and improve results?

Where does AI actually save time, and improve results?

Running campaigns is time-consuming. Solutions like Agentic AI now orchestrate end-to-end campaign workflows, audience building, trafficking, QA, pacing, and routine optimizations, so teams focus on strategy and creativity. Many leaders (94%) are investing broadly in AI to drive efficiency and impact, and 49% of marketers use it daily for image and video generation, shifting repetitive tasks from people to tools. By quickly combining past and current performance data, AI can pre-optimize before launch and refine mid-flight, while marketers steer the message and experience.

“AI uses past campaign data to optimize performance before launch, continues learning during the campaign, and refines strategies based on the insights it generates, driving better results over time.”

PubMaticHoward Luks

Takeaway: Experian’s solutions streamline campaign workflows, allowing marketers to focus on creativity and strategy while improving results.

3. How do AI and human strategy work together in real time?

How do AI and human strategy work together in real time?

AI handles real-time data analysis and optimization, freeing marketers to focus on strategy, messaging, and creativity. By defining audiences once and activating them across platforms, teams can adapt quickly and confidently. At Experian, we combine machine intelligence with human insight to deliver smarter, more agile campaigns.

“AI analyzes data, pulls insights, and automates optimizations, allowing marketers to focus on strategy, messaging, and creativity instead of spending time digging through numbers and data.”

AdRollLizzie Chapman

Takeaway: Experian solutions empower marketers to adapt quickly and confidently, combining human strategy with insights.

4. What does privacy-first look like now?

What does privacy-first identity look like now?

Relying on simple, static data points is no longer enough. A modern approach to identity blends deterministic data (like known identifiers) with modeled components, ensuring data remains de-identified where possible. Clear, transparent guardrails, permitted-use policies, retention limits, sensitive-category blocks, and audit trails, help brands balance personalization with privacy, build trust, and respect user choice.

“A new blend of identity systems combines deterministic data, known identifiers, and model driven components, creating fresh ways to address identity and activate campaigns with precision.”

OptableVlad Stesin

Takeaway: Experian’s privacy-first identity solutions help brands balance personalization with safety, ensuring trust and compliance.

5. Which new data signals matter, and why?

Which new data signals matter, and why?

AI is unlocking a new generation of data signals, like content context, sentiment, emotional tone, suitability, attention, and commerce intent, that go beyond legacy identifiers like cookies and demographics. These signals can help brand messages appear in the most relevant environments and by high-value audiences. Used well, they improve relevance, avoid placements near unsuitable or off-brand content, and drive stronger campaign outcomes.

“Unlocking new data sets (like emotion, sentiment, and context), AI is creating innovative ways to connect client content with advertising opportunities and rethink how we approach the market.”

PMGSam Bloom

Takeaway: Experian’s solutions use advanced data signals to help marketers create more effective and innovative campaigns.

Auto marketers: It’s time to pay attention to Gen Z

What generation already has 68 million consumers, is set to be the largest generation ever, and $360 billion of disposable income? While you may think these attributes describe millennials, they are actually a portrait of Generation Z, better known as Gen Z, the newest generation that is emerging in the marketplace. Gen Z is beginning to make an impact worthy of focusing your next auto marketing campaign around.  Gen Z and the automotive market  Made up of consumers born after 1996, Gen Z is ready to be noticed and become a force to be reckoned with in the market. In the automotive market alone, Gen Z made up 3.8 percent of all new vehicle registrations in the first quarter of 2019. While that number may seem small, consider the fact that in 2015—just four years ago—they only made up 0.5 percent of new vehicle registrations. These are statistics that should make automotive marketers pay attention.  Digital consumption of Gen Z   Most marketers tend to lump Gen Z with millennials – after all, they grew up with smartphones and social media, so how different can they be than the generation that came of age with the Internet? However, unlike millennials, Gen Z is considered a true “digital generation” – performing many of life’s day-to-day activities online. This means that they do a lot of research when shopping for a product. In fact, according to the Center for Generational Kinetics, 52 percent of Gen Z has looked at online reviews for a product while shopping in-store.  But how do digitally native consumers impact automotive marketers? In order to sell cars, marketers’ messages need to be relevant. Like many other generations, Gen Z interacts with brands across a number of different devices and touchpoints. They’re constantly bombarded with messages and advertisements, so much so that it becomes information overload.  Auto marketing to Gen Z To create consistent messages that resonate, brands need to communicate across these different touchpoints and tell a story that is relevant to your audience. For example, you wouldn’t show an advertisement of someone buying their dream sports car to a member of Gen Z. Most of these consumers are buying their first car, so it would typically make more sense to show them ads for economical, reliable, sedans or cross-over SUVs.  Historically, automotive marketers have relied exclusively on CRM data, but this strategy isn’t effective when it comes to Gen Z, the fact of the matter is that they probably haven’t purchased a car from you previously.  Identity resolution and Gen Z auto marketing  The recipe for marketing success with Gen Z is identity resolution – combining your first-party identity signals across channels with third-party resources, as well as advanced technology, such as machine learning and artificial intelligence, to truly create and deliver campaigns that are relevant to the youngest generation. The more knowledge marketers have on your audience, such as demographics, life events and purchase behavior, enables them to tailor the messages to the audience in a way that will cut through the noise and resonate.  As more members of Gen Z come into the marketplace, automotive marketers will want to ensure they’re meeting them where they are, delivering messages that matter to them. This will help marketers not only sell more cars, but also begin to create relationships that could last for years to come.   Your identity resolution partner  Experian is here to help you create an identity resolution strategy that will take your automotive marketing campaigns to the next level. We help brands put real people at the center of their business by resolving fragmented identity signals. Deliver personalized, relevant messages across channels to effectively target your ideal customers. Get started with identity resolution today! Contact us today

‘Tis (always) the season for audience optimization

As summer fades, marketers are gearing up for another campaign cycle. It’s a process that repeats itself annually, but we can’t just copy-and-paste our plans. With each passing year, the media landscape changes drastically, as do the behaviors of the audiences we are trying to reach. As ever, marketers have to be strategic—and nimble—to reach the right customers at the right time, with messaging central to seasonal events and personal preferences. Marketers can ensure their messaging reaches the right customers with audience optimization.  Reach target audiences this season  It can be a hassle to create custom audience segments and bespoke creative messaging every time the seasons change, but now, more than ever, we must ensure brand campaigns are as timely, relevant and personalized as possible. In a world of multitasking and multiscreening, there’s an expectation among consumers that all communications they receive are relevant to them—especially from brands.  This is why it’s critical to understand your audiences and how to engage them through the most effective channels.  To help marketers win the battle for consumer attention—and sales—4C developed the Scope platform. This self-serve software arms brands with powerful tools for managing audiences and optimizing campaigns across channels including TV and digital. So, whether it’s building an efficient media plan, buying targeted ads, or measuring business outcomes, audience optimization is truly in scope.  Deliver audience-based marketing messages across the TV and video space   Recently, 4C teamed up with Experian to expand our audience marketplace across linear TV, OTT and social media. Brands using the Scope by 4C™ platform can leverage Experian data across a variety of planning and buying use cases, including audience-based linear TV planning and programmatic scatter buying; OTT campaigns across FreeWheel, Telaria, and SpotX; and social advertising on Facebook, Twitter, and Pinterest.  Scope’s TV Planner allows marketers to combine historical cost and ad occurrence data with Experian audiences to create customized TV plans in minutes. The outputs go beyond GRPs to maximize in-target impressions for a secondary audience as well as indexing high against the primary demo. With audience-based TV planning brands can truly maximize their upfront buys and use the fantastic reach of linear television for seasonal performance marketing, not just brand awareness.  OTT harnesses the big-screen, living-room impact of TV with the targeting precision and flexibility of digital. By using Experian segments to create OTT audiences in Scope, brands can really focus on creative strategy, using the immersive power of video to drive specific business outcomes.  From a social perspective, we can combine the pinpoint targeting marketers have come to rely on from platforms like Facebook with advanced segmentation enabled by Experian. The output is high-performing audiences that can be reached at scale with dynamic creative to achieve unparalleled ROI.    Focus marketing strategies on audience optimization this season   Leveraging customized audiences across channels is the modern approach to marketing and has completely shifted the way marketers target consumers. With the relationship between 4C and Experian, there is now a better way for marketers to identify the most valuable potential customers, uncover the most appropriate messaging, and execute campaigns across the most engaging channels – during peak seasonal campaigns and every single day.
