A Dutch company has printed the structure behind its agentic shopping for stack, and the diagram makes an argument the remainder of the market has principally averted: the issue with agentic media shopping for is just not the brokers. It’s the chain of command they inherited.

Lars Postmus, proprietor of Draft Digital and Draft Media, set out the case in a LinkedIn post carrying a relative timestamp of two weeks, inserting publication in mid-July 2026. The put up was accompanied by a two-slide diagram printed below the draftdigital.nl area. One slide is labelled “The previous mannequin, reskinned”. The opposite is labelled “The Draft cockpit”. Between them sits a declare about value, management and headcount that touches each company at present operating agentic pilots.

The set off was mundane. Based on Postmus, he and three colleagues on the company – Floris Bruin, Barbara Palfenier and Jasmijn Kruis – reached their Claude utilization limits a number of occasions in a single working day. “Not as a result of one thing broke,” Postmus wrote. “As a result of we have been constructing too laborious. Good drawback. But it surely factors at an actual one.”

That actual one, in his framing, is just not a capability problem. It’s a structural one.

The primary slide maps the workflow that almost all holding firms and independents nonetheless run. A strategist briefs a comms planner. The comms planner briefs the specialists. Every specialist then buys on the platform they personal.

The diagram names 5 specialist roles: a social purchaser, a search purchaser, a programmatic purchaser, an audio and DOOH purchaser, and an offline purchaser. Beneath them sit twelve named endpoints. Social runs on Meta, TikTok and Reddit. Search runs on Google. Programmatic runs on PubMatic, VDS, Mediahuis and DPG. Audio and DOOH run on Triton and BroadSign. Offline runs on Ster and Advert Alliance.

The annotation on that slide is the purpose of the entire train: each field is one MCP name, each single time.

The Model Context Protocol is the connective tissue beneath most present agentic promoting work. It’s Anthropic’s open normal for wiring language fashions to exterior methods, and it’s the basis on which the Advert Context Protocol was constructed when AdCP launched on October 15, 2025 with six founding members and 23 further launch individuals. Platform after platform has since uncovered an MCP floor. Amazon opened a closed beta in November 2025. Meta, Google and a protracted checklist of measurement distributors adopted by way of 2026.

Every of these connections is helpful in isolation. Stacked right into a legacy workflow, they multiply. Twelve endpoints queried by 5 separate shopping for features produce twelve separate context hundreds, twelve separate authentication paths and twelve separate rounds of instruction. The invoice arrives in tokens.

“Many patrons. Many instruments. Tokens burn on each name, and the technique quietly fades on the way in which down. New tech, standard drawback,” Postmus wrote.

Two distinct complaints sit in that sentence. One is a value line. The opposite is what occurs when a plan is translated 4 occasions earlier than anybody spends cash in opposition to it.

What the cockpit rearranges

The second slide inverts the hierarchy somewhat than compressing it.

The strategist sits on the prime and, within the diagram’s phrasing, stays within the lead for the plan. 4 brokers function round that place: a Model Agent, a Efficiency Agent, a Inventive Agent and a Knowledge Agent. These 4 steer a single Purchaser Agent. The Purchaser Agent, in flip, talks to 1 Agentic Advert Platform described as one layer protecting all channels. Beneath that layer, the 5 channel teams from the primary slide reappear as feeds somewhat than as separate shopping for desks, every paired with an Optimisation Agent.

The arithmetic is the argument. One agent negotiating with one platform layer replaces twelve direct integrations queried independently. The slide data three claimed outcomes: the strategist retains management, calls fall and tokens keep low, and the technique stays within the plan.

None of these claims arrives with a benchmark. The fabric printed incorporates no token counts, no value comparability in opposition to the fan-out mannequin, no marketing campaign outcomes and no named consumer for the cockpit itself. What it incorporates is a topology.

The place the specialists land

That is the place the diagram addresses the query the business retains asking sideways.

“The specialists don’t disappear. They transfer up and feed an Optimisation Agent per channel. People do the considering, brokers do the lifting,” Postmus wrote.

The formulation is exact about what adjustments. Within the previous chain, a search purchaser executed inside Google Advertisements. Within the cockpit, that individual provides judgment to an optimisation layer that executes. The duty strikes. The experience is retained as an enter somewhat than as an operator operate.

Whether or not that distinction survives contact with a procurement dialog is a separate matter. An company that payments for execution hours after which automates execution has to discover a totally different foundation for the price. Ari Paparo made a model of this level in July 2025, when he argued that agentic AI threatens traditional DSP business models and that the worth proposition for media shopping for providers would shift towards strategic planning and artistic improvement somewhat than tactical execution. The cockpit diagram is, in impact, an working mannequin constructed on that premise.

What the token argument really prices

The declare on the second slide, that calls fall and tokens keep low, separates into two components, and the put up strikes between them. The incident that prompted it’s a improvement constraint. 4 individuals reached their Claude utilization limits whereas constructing the cockpit. That could be a subscription cap consumed by engineering work, and it carries no details about what a completed marketing campaign prices to run. The slide’s declare considerations manufacturing. The anecdote supporting it comes from the opposite facet of the ledger.

Manufacturing figures are skinny. At IAB Europe’s live agentic showcase on April 14, 2026, one demonstration accomplished a full process throughout three brokers working asynchronously in roughly 25 minutes, at roughly 50 euros in token and credit score expenses. Towards a media plan of any measurement that’s immaterial. Towards the amount of briefs an company processes in 1 / 4 it’s a line merchandise that didn’t exist two years in the past. Gartner has forecast that greater than 40% of agentic AI tasks could possibly be deserted by 2027, with escalating prices among the many causes.

The technical objection considerations what drives the invoice. Name depend is a weak proxy. Consumption tracks context quantity, and one agent loading twelve platform catalogues right into a single working context is just not clearly cheaper than twelve brokers every loading one. What consolidation removes is duplicated context: the temporary, the consumer historical past, the model guidelines, restated on each department. That could be a actual saving, and narrower than the diagram implies.

Format issues a minimum of as a lot as structure. Cloudflare’s Markdown for Agents, introduced on February 12, 2026, lower the token value of serving net content material to AI methods by roughly 80% by changing HTML to markdown on request. The corporate’s illustration is blunt: a heading consuming three tokens in markdown burns twelve to fifteen in HTML earlier than wrapper parts, navigation and scripts are counted, and its personal announcement put up measured 16,180 tokens as HTML in opposition to 3,150 as markdown. Twelve promoting endpoints of various technical maturity would produce comparable variance inside any agentic stack, no matter sits above them.

Then there’s the route of journey, which cuts each methods. Alphabet reported that Gemini serving prices fell 78% throughout 2025. Cheaper inference doesn’t reliably produce smaller payments. A Google engineer advised a advertising and marketing viewers in Might 2026 that token consumption follows Jevons paradox, the nineteenth-century remark that effectivity positive factors increase complete consumption somewhat than decreasing it, and that tokens would find yourself all through the workflow, attaching a visual value to work that had beforehand been invisible. Cloudflare answered the identical sample by opening a public beta of dollar-denominated spend limits in its AI Gateway on June 5, 2026.

An structure justified primarily on token economics rests on a quantity that retains falling and a quantity that retains rising. The second half of the Postmus argument is sturdier. Technique decay doesn’t observe the worth of inference.

The requirements backdrop

Postmus closed the put up by naming the place he expects the market to settle. “That’s the place AdCP and Agentic Promoting are heading. We’re constructing for it now.”

Each references are particular. AdCP is the Advert Context Protocol, ruled by the nonprofit AgenticAdvertising.org, which can be listed among the many affiliations on the Postmus LinkedIn profile alongside the Amsterdam College of Utilized Sciences. The protocol defines 9 core duties protecting the promoting lifecycle, from stock discovery by way of marketing campaign activation and reporting, and it has been contested for the reason that week it appeared. AdCP divided the advertising industry over whether or not standardising the transaction layer addressed or deferred the structural issues in programmaticprovide chains. Ari Paparo printed an in depth evaluation on November 3, 2025, supporting parts of the specification while questioning the media buying applications. Transparency objections surfaced in parallel, with debate over what agent-mediated buying does to supply chain visibility.

The governance panorama has since fragmented and partially reconverged. LiveRamp donated the User Context Protocol to IAB Tech Lab in November 2025, positioning it as an information aircraft beside AdCP’s management aircraft. IAB Tech Lab named its own umbrella initiative AAMP on February 26, 2026, having earlier opened an agentic RTB framework for container-based advertising. Prebid.org took stewardship of an open-source sales agent in January 2026 and placed publishers at the centre of its agentic roadmap. Scope3 co-founder Brian O’Kelley, who reposted the Draft Digital diagram, printed adagents.json as a proposed replacement for ads.txt on March 30, 2026.

Hostinger

Affinity joined AdCP as a founding member in June 2026. What the protocol has not gathered is the demand facet that issues most: Google, Amazon and The Commerce Desk haven’t adopted it. That absence is materials right here. A single Purchaser Agent speaking to 1 agentic advert platform assumes that platform reaches the stock the plan requires. The place the biggest shopping for methods sit exterior the protocol, the fan-out the diagram removes reappears elsewhere within the stack.

Whether or not the market information helps the premise

Two separate readings can be found, and they don’t agree.

The effectivity case has vendor proof behind it. In a December 2025 marketing campaign on PubMatic’s AgenticOS, the company Butler/Until reported 40% extra impressions than comparable non-agentic exercise, a 5.5x value effectivity and a 98% common video completion charge, on a single check. PubMatic launched AgenticOS with live campaigns running on January 5, 2026. AdRoll and PubMatic connected agents to diagnose programmatic deal problems in April 2026. Draft Digital itself provided the buy-side agent for what Broadsign described because the first fully agentic OOH campaign, introduced on Might 27, 2026, for Dutch charity lottery Lot of Happiness throughout World Netherlands stock, utilizing AdCP because the communication normal between the 2 brokers.

The counter-reading is newer and fewer flattering. DataBeat’s June 2026 US Programmatic Tendencies Report discovered that conventional programmatic buyers held a 13.4% CPM advantage over AI agents throughout the Might 2026 information interval, close to parity somewhat than the multiples early vendor checks instructed. And the corporate that has pushed agentic promoting hardest has been shrinking: Scope3 cut engineering and sales staff in February 2026, 5 months after business staff reductions in August 2025.

Adoption inside companies stays uneven. Analysis lined in April 2026 discovered that 87% of agency professionals considered the traditional agency model broken, with agentic AI reaching 46% of surveyed companies. Adoption clustered in low-consequence duties: ideation at 86.9% and analysis at 84.0%, in opposition to media planning at 29.1% and media shopping for technique at 22.1%. The phases the place the cockpit diagram proposes to function are exactly the phases the place uptake has been slowest.

Why the structure query issues now

A cluster of bulletins on June 11, 2026 – Mediaocean’s NIVO intelligence layer, Magnite’s Orchestration coordination product and Teads’ EngageOS – prompted the query of who controls the buying layer now. Per week later, additional launches from DoubleVerify and LiveRamp confirmed that agentic ad tech was moving on the buying layer directly, with Mediaocean survey information displaying 60% of entrepreneurs planning to lift AI media spending within the second half of 2026.

Nearly all of that building has come from the promote facet or from expertise distributors. The Draft Digital slides come from a purchaser, and reply a distinct query. Distributors are constructing coordination layers between brokers. Postmus is describing the place the human sits relative to these layers, and what turns into of the individuals who used to sit down between the strategist and the spend.

Omnicom raised the identical workforce implication from the holding firm facet, as famous when Big Tech recorded 150 billion dollars in first-quarter advertising revenue. The framing that automation frees groups for technique is acquainted from earlier waves of programmatic improvement. Whether or not the result preserves human roles at equal scale is answered by the cockpit diagram by way of assertion somewhat than proof.

What the put up doesn’t set up

The fabric is a LinkedIn put up and a two-slide diagram, not a product launch, a technical specification or an audited outcome. No token figures accompany the declare that calls fall and prices drop. No consumer is called for the cockpit. The Agentic Advert Platform on the centre of the second slide is just not recognized as a vendor product or as inside tooling. The 5 specialist roles are described as transferring up with none assertion about how many individuals that includes.

Engagement was modest at seize: 28 reactions, three feedback and one repost, on a profile with 4,885 followers. The repost got here from O’Kelley, whose firm co-founded the protocol the put up endorses. One public remark engaged with the substance. Nirar Punj, a efficiency advertising and marketing specialist, wrote: “This resonates a lot with our personal token challenges! Love the strategist-centric strategy.”

Hostinger

That could be a small pattern, and likewise a second practitioner reporting the identical constraint.

The query beneath

Learn in opposition to the AdCP debate, the diagram reframes somewhat than resolves the displacement query. The protocol was designed to let brokers transact throughout platforms with out bespoke integration work. If that succeeds, the operator operate inside every platform interface loses its shortage. What survives is judgment about allocation, positioning and artistic route, which the cockpit locations on the prime and calls the plan.

The counterargument is straightforward. Routing each channel by way of one purchaser agent concentrates decision-making inside a system whose reasoning is tough to audit, at a second when the business has not settled how agent-mediated shopping for studies its provide path. The transparency objections raised in opposition to AdCP in November 2025 apply with extra pressure, not much less, when the fan-out is changed by a single layer.

Postmus framed the market’s present exercise generously. “Proper now the entire market is testing Agentic,” he wrote, earlier than including: “However most of those checks don’t repair the true factor but. The strategist drawback.”

The diagram is a declare about the place management belongs. The proof that it produces higher outcomes, at decrease value, with the specialists intact, has but to be printed.

The put up was reposted by Brian O’Kelley, co-founder and chief govt of Scope3 and a founding member of the Advert Context Protocol.

What – A two-slide structure diagram and accompanying commentary arguing that present agentic promoting pilots protect the briefing chain that causes each token value and technique decay. The proposed different locations the strategist on the prime, surrounds that place with Model, Efficiency, Inventive and Knowledge brokers, routes all exercise by way of a single Purchaser Agent into one agentic advert platform, and converts 5 specialist shopping for roles into inputs to per-channel Optimisation Brokers.

When – Printed on LinkedIn with a relative timestamp of two weeks on the level of seize, inserting publication in mid-July 2026.

The place – The Netherlands, with the diagram printed below the draftdigital.nl area. The named endpoints span Dutch and worldwide provide, together with Meta, TikTok, Reddit, Google, PubMatic, VDS, Mediahuis, DPG, Triton, BroadSign, Ster and Advert Alliance.

Why – The fabric addresses the working value and management query that companies operating agentic pilots haven’t resolved. Twelve platform integrations queried by 5 separate shopping for features multiply token consumption and dilute the unique plan. The design additionally takes a place on displacement, holding that specialists transfer upward into optimisation roles somewhat than out, at a second when adoption information reveals agentic tooling reaching solely 22.1% of media shopping for technique work and impartial measurement inserting agent efficiency close to parity with standard shopping for.
