A shift is happening across the marketing industry—and AI-powered marketing automation is accelerating it faster than many expected.
On July 9, 2025, WPP, one of the world’s largest advertising groups, cut its full-year sales forecast, citing a major reason: clients are now using AI to take marketing operations in-house. According to Reuters, this trend—combined with tightened budgets and uncertain demand—represents a structural shakeup in how companies think about marketing delivery.
For traditional agencies, it’s a warning sign. For platforms like ProjectBloom, it’s validation.
Let’s unpack what this move means—and why AI-powered marketing automation is no longer optional, but mission-critical.

The Big Picture: AI Reshaping the Agency Model

As brands become more comfortable with automation, cloud tools, and AI agents, they’re realizing that they can do what used to require an entire agency—with fewer people and faster timelines. This includes:

  • Content generation
  • Ad targeting and optimization
  • Campaign orchestration
  • Performance analytics
  • Social and email automation

These aren’t experiments anymore—they’re cost-saving, scalable realities.

WPP CEO Mark Read noted that the company is adjusting to “changing client needs,” as in-house marketing powered by AI becomes more viable and attractive. Simply put: AI is decentralizing marketing expertise.

 

Why Brands Are Taking Control

There are three core drivers behind this shift:

Cost Efficiency: AI tools eliminate layers of manual work, making campaign delivery cheaper and faster.

Control & Agility: Internal teams can pivot quickly without going through external workflows or timelines.

Personalization at Scale: AI enables real-time segmentation, content variation, and channel alignment that many agencies struggle to match.

This in-housing trend is not a rejection of creative support—it’s a rejection of rigid, slow-moving marketing operations.

The Agency Model Isn’t Dead—But It’s Being Rewritten

External partners will always have a role—but their value must evolve. Instead of execution, the focus is shifting toward strategic support, oversight, and creative excellence. The grunt work? AI is taking it over—and doing it better, faster, and cheaper.

Companies that invest in AI infrastructure today are positioning themselves not just to survive, but to lead.
