Modular AI design, not end-to-end platforms, is what marketers actually need, argues Havas data chief

Modular AI tools beat monolithic platforms for most marketing teams-they integrate with existing systems and keep data ownership with the brand. The best solutions often come from practitioners closest to the work, not top-down vendor rollouts.

Marketing Should Adopt Modular AI, Not Monolithic Platforms

The shipping container didn't change ships. It changed how cargo moved between them. That principle applies directly to how marketing departments should approach AI today.

The container revolution of the 1950s streamlined global supply chains by introducing a standardized, interoperable system. Before containers, ocean freight was slow, expensive, and labor-intensive. After them, loading times dropped from days to hours. The innovation worked because it didn't force the industry to rebuild its infrastructure-it made existing systems work better together.

Marketing faces a similar choice now. Vendors push end-to-end platforms and promise efficiency through data scale and proprietary solutions. Most marketing teams actually need something different: flexible, modular tools that integrate with existing tech stacks.

Black Book vs. Black Box

A "black box" approach is agency-owned and one-size-fits-all. A "black book" approach is modular and transparent, built for specific client needs.

In a black book system, data decisions prioritize context over quantity. Relevance, freshness, data rights, cost, and geographic validity matter more than sheer scale. The logic is visible and adaptable, not hidden inside a vendor's proprietary system.

Your tech stack should matter more than your agency's. Too many agency-client relationships create unnecessary technology dependence. Brands shouldn't reorganize around their agency's AI tools. They should own their data, institutional knowledge, and intellectual property-and keep them even after the relationship ends.

Put AI Tools in Practitioners' Hands

The container was invented by Malcolm McLean, a trucker, not an engineer. He understood shipping's actual problems because he lived them.

The same principle applies to AI agents and automation. The practitioners closest to the work often design the best solutions. A modular approach means building low- and no-code tools that let teams create agents for their own workflows. Engineers and data scientists then industrialize what works, rather than rolling out agents that add noise instead of business impact.

Marketers face constant pressure to adopt new AI platforms. Efficiency claims arrive daily with little validation. Investors declare winners before commercial results appear.

But ROI doesn't come from the loudest story. It comes from solving actual business problems with solutions that work in practice, not just in presentations. Sometimes that solution is unglamorous-like a metal container that changed the world.
