AI won’t replace media agencies. It will redefine what clients value most
Opinion
At Postcode Lottery Group, conversations about transparency, effectiveness, and agency value go beyond marketing performance. They become about maximising social impact.
Every few months, another headline predicts that AI will make media agencies obsolete. If advertisers can plan campaigns, interrogate audiences, optimise media and generate reports using AI, why wouldn’t they simply bring everything in-house?
It’s a fair question. At Postcode Lottery, we’re investing in our own AI capabilities and bringing more intelligence, data and learning closer to the business. Yet that investment has reinforced, rather than reduced, our belief in the value of agency partners.
AI isn’t changing whether we need media agencies. It’s changing what we need them for
Postcode Lottery occupies an unusual position because our objectives differ from most advertisers’. Unlike brands chasing market share or quarterly sales targets, every pound we save, or invest more effectively, means more funding for the charities that support communities, people and the planet.
That means conversations about transparency, effectiveness and agency value become about more than marketing performance. They become about maximising social impact.
Historically, agencies have been valued for their buying power, execution and access to media. Those capabilities remain important, but AI is making many operational tasks faster, more efficient and increasingly accessible. As a result, agencies’ real value is shifting away from process and toward strategic judgement.
The agencies that will thrive won’t simply be those that execute brilliantly. They’ll be the ones that challenge our thinking, identify opportunities we haven’t seen, connect market signals to business decisions and help us navigate an increasingly fragmented media landscape with confidence.
That shift has implications for how clients and agencies work together.
At Postcode Lottery Group, we apply common principles across our agency relationships in the Netherlands, the UK, Sweden, Germany and Norway, while giving each market the flexibility to reflect local audiences, media landscapes and business needs. The aim isn’t to impose a single global model, but to combine shared learning and standards with strong local expertise.
As we expand into new markets, that approach gives us a strong foundation from day one – scaling what works while adapting to the unique needs of each country. Those principles are:
1. Transparency is the foundation, not the differentiator
Transparency should no longer be viewed as a competitive advantage. Clients increasingly expect openness across pricing, trading, technology, data and AI. Trust should come from clarity, not complexity. Once that foundation is established, agencies can focus on creating value rather than defending their model.
2. AI should raise the value of people, not replace them
The biggest opportunity for AI isn’t reducing headcount or lowering costs. It’s removing repetitive, low-value tasks so talented people can spend more time on the work that matters most: strategic thinking, creativity, commercial challenge and identifying new opportunities for growth. AI should amplify expertise, not replace it.
3. Clients should own more intelligence. Agencies should add more judgement.
As advertisers build stronger first-party data capabilities and develop their own AI infrastructure, more institutional knowledge will naturally sit within the business. That’s a positive shift. It creates continuity and ensures core intelligence remains close to the organisation. But it also raises the bar for agencies. Their role becomes less about holding information and more about applying experience, external perspective and commercial judgement to help clients make better decisions.
4. Agencies should challenge, not just deliver
The future value of agencies won’t be measured by the number of presentations they produce or hours billed, but by the quality of their recommendations. We don’t need partners who simply confirm what we already know. We need partners who proactively challenge assumptions, identify new opportunities, and bring the quality of strategic thinking that is often reserved for a pitch throughout the lifetime of the relationship.
Ultimately, AI won’t diminish the role of media agencies, it will redefine it. As technology takes on more of the process, the premium on human judgement, creativity and commercial challenge will increase.
For advertisers like Postcode Lottery, where every marketing pound has the potential to generate more funding for charities, that’s the kind of partnership that creates real value.
