The platforms are winning. But agencies are fighting back!
July 8, 2026
Welcome to Edition 16 of The Takumi AI Brief.
My weekly read on the AI shifts marketers should actually care about.
A three-minute read covering one trend that matters, one shift to watch, and what I would do if I were in the CMO chair.
01 · The Trend That Actually Matters
We have seen this pattern before.
Google built the search auction, defined the metrics and trained the market to operate inside its dashboard.
Meta followed with audiences, creative tools, optimisation and measurement.
Agencies adapted. New specialisms appeared. Holding companies reorganised.
The platforms kept most of the value.
Now the same dynamic is playing out again, only much faster.
This time, the platforms are not simply taking the media transaction.
They are moving into planning, creative, activation, optimisation and measurement.
In other words, they are moving from selling access to owning more of the operating model.
Google's real advantage is not just Gemini.
It is the ecosystem around it.
Ads, Analytics, YouTube, Search, Merchant Center, Cloud and first-party signals are increasingly designed to work as one connected environment.
Meta wants its algorithms deciding which creative, audience and placement combination wins.
Amazon wants commerce, media and measurement sitting inside one system.
The appeal is obvious. Fewer dashboards. Faster decisions. Less manual work.
The risk is just as obvious.
The same company is becoming the seller, operator, optimiser and scoreboard.
No CMO would accept that structure anywhere else in the business.
In marketing, we often call it convenience.
Agencies understand the threat.
WPP, Publicis, Omnicom, Dentsu and others are building their own agentic infrastructure, workflows and intelligence layers because they know what happens if the platforms own everything.
The agency is reduced to implementation.
That is why the real battle is no longer over who runs the campaign.
It is over whose intelligence layer runs the marketing.
The platform wants that layer.
The agency wants to build that layer.
The brand should want to own it.
02 · The AI Shift to Watch
Agency-built agentic systems are a real response to platform power, and in many cases a necessary one.
The best agencies bring something the platforms do not.
Category knowledge. Cultural judgment. Customer understanding. Creative instinct. And the ability to connect brand, media, data and experience across the business.
That is valuable.
But there is a catch.
An agency-branded operating system can still become rented infrastructure if the client cannot take the learning with them.
If the workflows sit inside the agency, the prompts sit inside the agency, the optimisation history sits inside the agency and the accumulated intelligence disappears when the relationship ends, the brand has simply exchanged one dependency for another.
That is the bit CMOs need to look at closely.
The new agency pitch is no longer, "we have better people."
It is, "we have a better machine."
Fair enough.
But the next question should be immediate.
Who owns the machine when we leave?
This is where agencies have a genuine opportunity to become more important, not less.
They can help brands design the architecture, challenge platform logic, create governance, build workflows and connect systems that internal teams cannot yet build alone.
But the value proposition has to move from operating the machine to helping the brand build one it can eventually own.
Otherwise, agentic transformation becomes a new wrapper around the old retainer model.
03 · If I Were in the CMO Chair
If I were in the CMO chair, I would stop asking whether we should use platform AI or agency AI.
That is the wrong choice.
I would use a much simpler framework.
Own
I would own anything that becomes strategic memory.
Customer data. Brand code. Audience logic. Measurement definitions. Prompt libraries. Governance rules. Product knowledge. Approval logic. Agent permissions. Share of Model. The learning generated from every campaign and customer interaction.
These are not supplier assets.
They are business assets.
If the brand does not own them, it does not really own its marketing intelligence.
Co-own
I would co-own the layers where capability still needs to be built with partners.
Creative automation systems. Agentic workflows. Experimentation design. Martech architecture. Cross-platform orchestration. AI visibility programmes. Measurement frameworks.
This is where agencies can be genuinely valuable.
Not as operators sitting between the brand and the dashboard, but as co-architects helping build a system the client can run, improve and eventually internalise.
Rent
I would rent specialist capability where external scale or expertise still makes sense.
Media infrastructure. Platform access. Specialist production. Market expertise. High-end craft. Technical tools. Short-term execution capacity.
There is nothing wrong with renting capability.
The mistake is renting strategic memory.
The portability test is simple.
Can the data move? Can the workflows move? Can the accumulated learning move? Can another partner operate the system? Can parts of it be brought in-house later?
If the answer is no, you have not built an operating model.
You have rented one.
That is the distinction CMOs need to make now.
Platforms will remain essential.
Agencies will remain valuable.
But neither should be allowed to become the sole keeper of the brand's intelligence.
The platforms own the rails.
Agencies can help navigate them.
The brand must own what the journey teaches.
Otherwise, the CMO is not choosing between partners.
They are choosing who to depend on.
Until next week,
keep building, keep questioning.
