This post kicks off our guest post series, where we roll out the welcome mat for the sharpest minds in advertising, marketing, and tech to weigh in on the latest shifts and breakthroughs shaping the industries.
Meet MadSense, The Ad Tech Philosopher and Market Analyst
Our first guest is MadSense. If AdTechGod is known for influence and signal amplification across the ecosystem, MadSense earns a different title: Ad Tech Philosopher. He approaches ad tech the way a philosopher approaches complex systems, using concepts, mental models, and first-principle thinking to explain why the market behaves the way it does, not just what happened. His strength lies in translating dense, technical change into clear, structured thinking that marketers and operators can actually apply.
That perspective is what makes MadSense’s voice valuable right now That perspective is what makes MadSense’s voice valuable right now. In this piece, he turns that lens on one of the most consequential moves in the agency world this year: Omnicom’s acquisition of IPG. Rather than treating it as a simple scale play or consolidation headline, he examines what the deal reveals about how agency models are evolving and what needs to change for them to stay viable in a market shaped by data, identity, and AI.
He frames Omnicom’s acquisition of IPG as a search for the agency model’s proper form. Here’s why.
Why Omnicom Needed More Than Just the Right Parts
The advertising vivarium is going through some real shifts in its ecology, and not all of them are healthy. Parts of the agency model are under stress and clearly in need of repair. That’s the context for Omnicom’s move. With this deal, they’re trying to reset the environment by changing where the light, food, and water flow, setting the stage for a new structure to take shape. If you borrow an idea from hylomorphism, the industry has plenty of hyle, the raw parts, but it’s still searching for the right morphe, the form that gives those parts meaning.
As plenty of people have already said, Omnicom’s acquisition of IPG helps on a few obvious fronts: more scale, stronger analytics, and a tighter, more vertically integrated sales and marketing model. All true. But those benefits are really just the hyle, the body, the parts of the deal.
As the philosophers would put it (and don’t worry, we’ll keep this short), parts alone don’t make something whole. What really matters is how those parts are organized and aligned. That’s where the morphe comes in, giving the whole thing its form and soul. In Omnicom’s case, that form has been hiding in plain sight. It’s a bit like a pile of Lincoln Logs on the floor. All the pieces are there, but without the right connection, you don’t quite have a cabin yet.
To reach full hylomorphism, meaning the right parts with the right alignment, Omnicom needs to add one key component that wasn’t in the original box.
As a business, Omnicom has long followed a rent-don’t-buy mindset, not unlike the financial “experts” online who insist you should invest your extra cash instead of buying a house. Honestly, Omnicom could have sponsored half those posts. They rented RampID to build Omni ID, relied on i-framed partner portals inside Omni, now rebranded as OmniPlus, and leaned early and heavily on offshoring for data and platform operations. If you want to borrow another Greek word, renting wasn’t just a tactic; it was their ethos. In hylomorphic terms, Omnicom had plenty of hyle, borrowed tools and parts, but not quite the morphe, the owned structure needed to hold everything together.
But the vivarium has changed. The air is now thick with privacy regulation, AI, and alternative IDs, and that shift changes what can survive. Almost overnight, first-party data went from “nice to have” to absolutely necessary. GDPR made that pretty clear. If you’re not the data controller, you’re renting access to your own insights. On top of that, Omnicom’s close relationship with Google comes with real limits. Advanced analytics inside Ads Data Hub live behind layers of k-anonymization, which makes deep analysis harder the further you push it.
The Asset That Made Everything Else Matter
Once the problem is clear, Omnicom leadership really has one job: go buy the data. Everything else around the deal helps tell a broader story, but it also does a bit of work to soften the spotlight on the one piece that truly mattered. The company they envisioned is now mostly assembled. Scale, tighter sales and marketing alignment, and the rest are real benefits, but they’re not the core of the move. Acxiom’s Real ID is the animating force of this agency’s soul. It’s the piece that gives the rest of the hyle something to organize around and finally allows the morphe to take shape.
That’s because modern analytics, audience strategy, retargeting, and real-time optimization all depend on first-party data, resolved through alternative IDs.
That’s because modern analytics, audience strategy, and real-time optimization all depend on first-party data, resolved through alternative IDs. Without that, everything downstream gets harder. Imagine paying a few cents every time you put on your favorite shirt. That’s essentially what Omnicom was doing with identity. LiveRamp took a cut on every ID match. On top of that, advanced analysis was fragmented. Obfuscated data inside Google’s platform had to be stitched together with rented and anonymized first-party data coming from elsewhere. The pieces were there, but they never quite fit cleanly.
Ownership Was Step One, Execution Is the Test
This deal reads like a bit of a redemption arc for Omnicom. They’ll almost certainly support multiple IDs in their identity stack, but owning a first-party data set changes everything. It puts them on more equal footing with Publicis’ CoreID and WPP’s AmeriLink, and it’s a much stronger position than Horizon’s approach of relying on a third party like TransUnion to support Blu. Framed this way, the acquisition starts to make a lot more sense.
To fully take shape as a data-centric organization, Omnicom had to finish the job. Completing that hylomorphic profile meant adding a first-party data foundation, something that could give real structure to all the existing parts. Competitors have already shown how powerful it is to connect data, media, and creative strategy through a central identity layer that they actually control. Matching, or beating, that capability wasn’t optional. For the Growth teams, or really the New Business teams, this matters a lot. Pitches centered on a connected data ecosystem have proven effective for competitors like Publicis.
Changing an organization’s entire operating model isn’t something most companies are eager to take on. But if the goal is to build a truly customer-centric marketing organism, one grounded in audience strategy, creative customization, and serious cross-channel analysis, Omnicom didn’t have much choice. Now that the key pieces are finally in-house, the real test becomes how they’re assembled. The hyle is there. Whether the morphe comes together depends on execution.
The open questions are the interesting ones. How does this new data connectivity shape their AI ambitions? Do insights and reporting actually get deeper and more useful? And what does it say that so few IPG leaders are running major business units so far? For now, all we can do is watch. Still, the direction of travel suggests the future is, at least mostly, bright.
The Cost of Getting the Form Right
Omnicom paid a hefty $9B for data and scale. For that price, they picked up everything Interpublic Group brought to the table, including a large client roster and, most importantly, a first-party data set. It’s hard not to compare that to Publicis, which paid $4.4B for Epsilon just six years ago. Against that backdrop, $9B feels expensive, even if the deal was done entirely in stock.
Still, the underlying strategy holds up. Omnicom needed a first-party data set with an identifier that could actually sync across platforms. Without it, all the surrounding hyle lacked a stable form. With it, the morphe finally has something solid to work around. They got what they needed, even if that asset is still early in how fully it’s being put to use.
