The Publication
Working notes from operating the model — media economics, measurement after attribution, agentic commerce, and the governance that holds AI accountable to the P&L. Written by the people running the system.
Measurement
Attribution answered a question the industry has stopped asking. The instruments that decide budgets now — incrementality, modern MMM, and the ledger as referee.
Agentic Commerce
Shopping agents already compare, negotiate, and purchase. The new shelf is structured data — and machine demand is the best-counted revenue in the book.
AI Operating Model
The 80/20 doctrine in practice: which decisions stay human, and the thresholds, kill criteria, and metered cost that hold the line in writing.
Financial Governance
Nine-figure decisions run on numbers nobody can defend. One record of truth, frozen definitions, and a close both sides sign.
Media Economics
Averages defend budgets; margins move them. Allocation by marginal contribution, and a budget re-cut on evidence at a set cadence.
Performance Creative
Paid social is a creative-velocity problem wearing a media badge. Agents assemble the variants; operators own what the brand says.
Retail Media
The fastest-growing line on the plan, and the least honestly counted. Incrementality by SKU, priced against contribution after margin and fees.
Growth Economics
Every budget is a forecast, acknowledged or not. Response curves and scenario bands before capital moves — and a model with an error rate everyone can see.
