Ad Age’s latest Agency Brief highlights Dept’s senior AI hire, S4 Capital’s subscription push and a cultural reset at WPP, giving CMOs and procurement leaders a snapshot of how agency models are shifting around AI, pricing and new business discipline.
In the piece, Ewin Larkin at Ad Age reports that digital network Dept has hired former WPP Open executive Roy Armale as chief product officer, tasking him with scaling its Orchestrate platform to unify marketing and engineering workflows in a single AI-led system. He also summarizes S4 Capital’s latest earnings call, where Sir Martin Sorrell underlines both the promise and friction behind subscription pricing.
For ID Comms’ audience, the article’s sharpest moment is the quote of the week, where David Indo reflects on WPP’s historical 'degree of arrogance' in pitches and how that is changing.
This combination of leadership moves, commercial experiments and cultural shifts makes the Brief a useful barometer for how large networks are trying to reset their value story in an AI-first market.
In the Brief, S4 Capital’s executives explain that their shift to a subscription model is still in its early days, with one enterprise client fully live and three more in discussion, constrained by existing contracts, procurement guardrails and cautious AI adoption. The message is clear: the billable hour is under pressure, but the replacement is not yet mature.
On the earnings call, Sir Martin Sorrell frames the challenge as change management, noting that companies often struggle more with organizational re‑wiring than with the technology itself.
External reporting has filled in more detail: by 2025 S4’s net revenue had fallen around 10–11% year on year to roughly £673 million, while about half its revenue has historically depended on big tech clients whose marketing budgets have flattened even as their AI infrastructure spend has grown by over 100%.
Subscription deals are S4’s response, typically bundling senior talent, AI workflows and agentic systems for a recurring annual fee rather than a scope of hours.
For CMOs, the attraction is predictable cost for expanding AI capability: as models improve, the promise is more outputs for the same fee.
For procurement, the friction sits in re‑opening legacy contracts, getting comfortable pricing outcomes rather than inputs and managing volatile compute costs that agencies may not be able to absorb indefinitely.
The Brief’s quote of the week puts WPP’s cultural reset under Cindy Rose under the microscope, using a candid observation from David Indo to illustrate how client expectations of behaviour in the room are changing.
In the article, Indo reflects on WPP’s historical posture in competitive reviews: "For many years, WPP would attend presentations and there would be a degree of arrogance they would bring into the room with them; a degree of entitlement because they’d been so successful." He notes that sometimes this translated into confident, coherent pitches, but at other times it was 'jarring for the client'.
That contrast captures a wider industry inflection point.
Holdcos no longer win on scale alone; CMOs and procurement leaders want integrated capability, transparent commercial design and a partnership mindset grounded in humility and evidence, not legacy swagger. Under Rose, WPP is publicly emphasising simplification, AI-enabled integration and a sharper new business discipline.
For advertisers, this is an opportunity: it is easier to demand outcome-linked value, multi-disciplinary teams and better cultural fit when the incumbent model is already under pressure to reform.
From an ID Comms point of view, the most useful part of Larkin’s article is how it connects culture in the pitch room with the hard realities of pricing, AI adoption and governance. The quote from David Indo is more than a colorful anecdote; it is a reminder that confidence without empathy now loses business.
We see the same pattern across global reviews: advertisers reward agencies that combine technical capability with coachable, collaborative behaviors.
In that context, experiments like S4’s subscription model or Dept’s Orchestrate platform should not be judged on slogans but on whether they build advertiser confidence.
Do they improve visibility on who is doing the work, how AI is deployed, what data is used and how success is measured ? Or do they obscure the economics further, replacing one black box with another ?
In addition to the Dept and S4 stories, the Brief signposts other agency developments, including Omnicom’s audit of The Trade Desk’s fees, a new creative leader at Opinionated and a US Army review of its $4 billion account. Those storylines all speak to a single theme: the structures, incentives and economics of the agency world are in flux. For CMOs and procurement leaders, the next 12–18 months will be defined by how quickly they can translate this flux into better designed, more accountable partnerships.
