The AI Marketing Department
Sixteen modules, six stages, one director that does none of the work — and the ledger for the part every version of this pitch leaves out.
There is a beautiful poster going round: an AI marketing department for a local business, fourteen modules, three salaries and two agency retainers, gone, twenty-five minutes a week. The shape of that poster is right. What it never shows you is the arithmetic — which of those five cost lines was genuinely replaced, which was only assisted, and which is still yours no matter what you buy. This page draws the department and then prices it, live, against your own numbers.
Every box names the thing that runs it and what it owes you on Friday.
A diagram is easy. The test of a department is whether each module has an input, a job, an output and something it must put on the table every week. A module that produced nothing this week is flagged, not drawn. Boxes marked gate stop and wait for a human before anything reaches a customer.
“Three salaries, two retainers, gone” is a claim. This is the receipt.
Every cost line in a business is really a bundle of jobs. A marketing manager is planning, brand judgement, chasing vendors, reporting, deciding where the next dollar goes, and the relationships they hold. Some of those a machine carries completely. Some it carries most of the way. Some it must never be handed at all. So each line comes back replaced, assisted or still yours, and you get two numbers, never one: what goes if you accept every automation, and what goes with nothing lost. The gap between them is the part of the pitch nobody prints.
Three things stay yours, and no coverage score can buy them.
The reel says it out loud and then bills as though it did not: the owner still owns the offer, the price, and anything that sounds like a promise. Here that is not a disclaimer, it is enforced in the engine — those functions carry a coverage of zero, so they can never book a saving, and any cost line that is mostly made of them comes back still yours however good the rest of the maths looks.
The awkward ones.
Can an AI department really replace a marketing hire?
It can replace some of them completely, most of them partly, and a few not at all — and which is which depends entirely on what that person actually spends their week doing. A content creator's week is production, and production is the part machines are now genuinely good at. A marketing manager's week is a quarter planning and a sixth relationships, and the relationships are not a workflow. The ledger on this page breaks each role into its real jobs and prices them separately, because the role-level answer is always wrong in one direction or the other.
Why two savings numbers instead of one?
Because a single number always hides which side of the trade it came from. The first number is what goes if nothing is allowed to get worse — only the lines that are fully covered. The second adds the assisted lines at their real coverage, which means accepting that something drops a notch. The true answer for most businesses sits between them and it is the owner's call, not ours. You cannot make that call if only the bigger number was ever shown to you.
What does 'the director does none of the work' mean?
It holds the plan, hands each job to the module built for it, checks the result against the brand, and stops at the approval gates. It does not write the post, buy the media or answer the lead. That separation is the difference between a department and a pile of prompts: when one module changes, nothing else has to, because the director talks to a contract rather than to another prompt.
How is this different from wiring ten tools together?
Ten tools chained together break the first time one of them changes its output, and you find out from a customer. Here every module has a declared input, job and output, and owes a specific artefact every week — a dated plan, live post URLs, a reconciled close. A module that produced nothing is flagged. The chain does not silently keep running while producing nothing.
What is 25 minutes a week, honestly?
It is the approval gates, and this page counts them instead of asserting a number: every gate is a decision a human has to make, budgeted at four minutes, and the total moves when you change what the department runs. If you turn on paid media, reactivation and reviews, your time goes up, not down. Any pitch quoting a fixed weekly figure regardless of scope is quoting a slogan.
What will you never take off my desk?
The offer, the price, and anything that sounds like a promise. Those carry a coverage of zero in the engine, so they can never book a saving, and a cost line made mostly of them comes back 'still yours' no matter how good the rest of the maths looks. We would rather lose the line item than own your guarantee.
Can you price this against my real payroll?
Yes, free. Send the actual lines — salaries, retainers, the answering service everyone forgets about. You get the same three verdicts against your numbers with what stays human printed next to each one. If the honest answer is 'keep the person', that is the answer you get; a replacement you regret in month three costs far more than the salary did.
Want the ledger run on your real payroll?
Send the actual lines — salaries, retainers, the answering service you forgot about. We return the same three verdicts against your numbers, with what stays human printed next to every one of them. If the honest answer is “keep the person”, that is the answer you get.
