TL;DR: US buyers building an internal business case for agentic advertising should focus on three pillars: operational efficiency gains, accountability improvements that satisfy CFO and legal scrutiny, and a phased deployment model that controls risk.

Why Internal Cases Are Being Built Now

US programmatic buyers are under pressure from two directions. Media inflation is compressing the working media ratio of programmatic budgets. And CMO scrutiny of programmatic accountability has increased since the ANA's 2023 transparency study, which documented the scale of unaccountable spend in the US market.

Agentic advertising addresses both pressures. It reduces the cost of deal execution by automating negotiation. And it improves accountability by producing bilateral deal records that both buyer and publisher hold independently.

For buyers looking to take this to a procurement or finance committee, those two arguments need to be structured as a business case with quantifiable assumptions, a risk model, and a phased deployment plan.

The Three-Pillar Framework

Pillar one: operational efficiency. The cost of managing programmatic buying at scale is primarily human. Agency trading desks spend significant time on deal negotiation, campaign trafficking, discrepancy resolution, and reporting reconciliation. An agentic model reduces the time required for negotiation and can reduce discrepancy resolution workload by providing bilateral deal records that both parties can reference.

The business case should quantify current operational costs and model the expected reduction from agent-led negotiation. Pilot data from a defined test period is the most credible input for this calculation.

Pillar two: accountability and compliance. US CMOs and CFOs are under increasing pressure to demonstrate that programmatic spend is accountable. The bilateral deal record produced by an agentic marketplace provides a documented record of what every deal committed to, in a format that legal, finance, and external auditors can review.

The business case should quantify the cost of current discrepancy resolution, audit preparation, and reporting overhead, and model the expected improvement from bilateral deal documentation. It should also address the regulatory risk reduction from having auditable deal records under CCPA and emerging state privacy frameworks.

Pillar three: phased deployment to control risk. Internal stakeholders will raise concerns about agent autonomy. The business case should address those concerns with a phased deployment model: pilot with a defined mandate on a small budget, measure outcomes against the bilateral deal record, expand autonomy only on the basis of demonstrated performance.

This reflects the earned autonomy model that governs responsible agentic deployment: agents earn the right to increased autonomy through evidence, not assumption.

What to Include in the Business Case

A credible business case for agentic advertising should include:

A current-state baseline: operational costs, discrepancy rates, and time spent on deal management.

A quantified efficiency model: expected reduction in deal negotiation time, discrepancy resolution, and reporting overhead.

An accountability improvement model: how bilateral deal records change the audit posture and what the risk reduction is worth.

A phased deployment plan: pilot parameters, measurement criteria, and the criteria for expanding to full deployment.

A risk register: what could go wrong, how each risk is mitigated, and what the rollback plan is.

Alkimi's Role in the Business Case

For US buyers evaluating Alkimi as part of their agentic advertising business case, the relevant data points are the DealSheet's bilateral deal record (accountability pillar), the AAMP and AdCP standards alignment (risk mitigation, not proprietary lock-in), and the earned autonomy model (deployment risk control).

Alkimi's commercial team can support business case development with pilot data, integration documentation, and reference contacts from existing deployments.
