Duct tape is not a strategy: why marketing agencies need a tech rethink to win bigger clients

So, how can agencies deliver faster, smarter, and more securely for clients – but without burning out teams, losing their agility or creative edge and breaking the business?

The real client brief: stability, scalability, governance

When brands hire agencies, they expect seamless, enterprise-level delivery. They demand hyper-personalization, smarter data, seamless campaign orchestration, better customer experiences, more profitability and new revenue streams like retail media networks. For example, retail media networks increasingly expect uptime guarantees that look more like IT Service Level Agreements than campaign Key Performance Indicators.

This is especially true of Fortune 500 clients, where uptime, compliance, and attribution are non-negotiable. Enterprise brands expect the same from marketing technology as they do from IT systems: stability, scalability, and governance. A brilliant creative concept is worthless if the microsite crashes under load, if personalization breaks at scale, or if customer data is mismanaged.

At the same time, marketing outcomes are now directly tied to tech performance. Conversion rates depend on page load speed, engagement hinges on dynamic personalization algorithms and ROI attribution rests on integrated data flows.

But are agency systems up to the job?

Delivering all of this takes a strong system. Not a quick fix and a fragile stack that stalls growth, drains teams, and leaves agencies exposed.

But many agencies admit their tech environments aren’t up to the task. Tools don’t talk to each other, data gets siloed, and campaign performance is impossible to measure consistently. Nearly three-quarters (72%) struggle to merge data from multiple sources – a deal-breaker for personalization. And even more (81%) damn their martech infrastructure as ‘adequate’ or worse .

It’s easy to end up in this state in a fast-moving tech market with ever-tightening client pressures and shifting consumer behaviors.

Tech and data rule when budgets move

Meanwhile, budgets are shifting. WARC forecasts that retail media spending will surpass linear TV by 2026, proving that commerce-driven, data-rich campaigns are now the beating heart of marketing.

At this year’s Cannes Lions, the winners weren’t the flashiest creative stunts, but campaigns built on data, commerce, and purpose – proving that successful brands are no longer those with the loudest ideas, but those with the strongest systems behind them.

Agencies that can’t deliver enterprise-grade tech will be sidelined from this new era.

From short-term fixing to long term building

So, what’s the answer?

“The only way forward is systemic delivery,” says Dmytro Breslavets, co-CEO of P2H: “That means treating marketing technology not as a collection of one-off fixes, but as a long-term architecture designed to scale.”

Systemic delivery gives agencies the power to consolidate tools and data into a single customer view, automate journeys seamlessly across channels, and measure ROI in real time. It enables them to turn owned platforms into revenue-generating retail media networks, all while ensuring the reliability and compliance that Fortune 500 clients expect.

Just as importantly, systemic delivery protects agency margins and team energy, because the tech, not the people, do the heavy lifting and firefighting.

This isn’t about buying more tools, says Breslavets: “It’s about using fewer, more integrated ones, and building custom capabilities only where they create competitive advantage. It’s about rethinking how engagement is planned, executed, and measured. And it’s about rethinking tech investment.

“Building systems like this costs more upfront. But they multiply their investment in personalization that converts, campaigns that scale, and platforms that generate new revenue streams.”

Market moving towards nimble, end-to-end partners

Leading agencies are already starting to move in this direction. Rather than bolting together a fragile stack of freelancers, plug-ins, and off-the-shelf tools, they’re working with end-to-end, engineering-led partners who can help them create systems built for scale.

One such example is P2H Forge (part of P2H Group) – an end-to-end technology partner that reflects a wider shift toward systemic, partnership-driven delivery models in the marketplace. Rather than supplying tools or point solutions, P2H Forge works with agencies to design and operate the technology foundations that modern marketing demands. That means building architectures that support enterprise-grade reliability, unifying fragmented data for smarter automation, and embedding AI responsibly into customer experiences, from predictive analytics to dynamic personalization.

It’s a sign of where the industry is heading: away from quick fixes and toward durable systems that can carry the weight of modern marketing expectations. And agencies that embrace this shift aren’t just keeping up with client demands, they’re building the foundation for long-term growth.

It’s time to retire the duct tape and embrace the blueprint. As Breslavets sums up: “The future belongs to agencies that treat technology not as a patch, but as a platform for growth.”
