Twenty years in agencies taught me one simple thing: we do not bill clients for what they actually want to buy. An advertiser buys an idea, a judgement, a decision — and, in the end, a result. What we bill them for is something else: hours, amends, clicks inside platforms, a commission on what they spend. The invoice describes how the machine runs, not the value it produced.

I have watched that gap from every seat I have held. Client-side, where I was the one paying those invoices. Running a global account, where execution took dozens of people across dozens of markets. Running an agency, where my best experts spent their time on campaign set-up and reporting rather than on the thinking clients had come to buy.

Agents change that equation. Set-up, adaptations, optimisation and reporting go to machines that never sleep, never miss an alert and never forget an exclusion. That is not just a productivity gain: it is a guarantee of consistency, and above all a way back to billing for what genuinely carries value — strategy, arbitration, decision.

One conviction twenty years of campaigns have never contradicted: the first lever of efficiency is not targeting, it is the creative. A good message poorly distributed still sells; a poor message perfectly targeted sells nothing. Which is why media cannot be optimised after the fact, once a month, in a review meeting: it has to be optimised natively and continuously, at the pace at which creative wears out.

The context makes that urgent. AI has collapsed the cost of producing an ad, and feeds are filling up with content that is competent, smooth and interchangeable — the AI slop we are all swimming in. Producing a thousand variants costs nothing now; knowing which ones say something, and cutting the rest within hours rather than weeks, is the real work. That takes two things at once: a machine that optimises relentlessly, and someone whose job is to decide.

That is what I am building with mediagentic: an expert who builds the plan, agents that run it continuously, a flat fee with no commission and no billable hours. For the small and mid-sized companies and the start-ups that never had access to people like me, because their budget could not justify hiring them.
