Six weeks in: the honest balance sheet

You are sitting in a meeting. “AI changes everything,” the consultant says. You ask what it costs. And what comes back is: depends.

“AI changes everything” is a sentence without a price tag. After six weeks of complete rebuild — new operating system, own servers instead of cloud subscriptions, an AI agent as a permanent staff member — ours is on the table. This Sunday edition is the reckoning: every line item, including the embarrassing ones.

Swiss francs: the big items first

The honest calculation starts with hardware. For your own AI machine — top tier graphics card, mainboard, processor, all of it done properly — you put down around CHF 10,000. Anyone telling you that serious AI in your own building is free is selling you something else.

The second largest item is the agent itself. Over six weeks of intensive build-out it consumed around CHF 4,700 of computing power. That is build intensity, not steady-state operation — but it belongs here, because it appears in no brochure.

Next to that, the server line is almost touching: about CHF 30 a month for the rented machine that runs mail, calendar, storage and the automation. Deliberately the larger variant — honesty also means not quoting the budget model you are going to upgrade next month anyway. The cancelled subscriptions — password manager, productivity suite, cloud storage — cover that server bill. Nothing more. If you plan the rebuild as a savings programme, you are doing the wrong arithmetic. This is about ownership, not about saving.

Hours: the most honest currency

Around 200 hours across six weeks, evenings and weekends. No defensive number, no talking it down: this was a full rebuild of the digital life of a group of companies, and on every one of those evenings I knew what I was doing and why. Part of it was learning curve — new operating system, new tools — and that part you pay exactly once.

One thing matters if you are doing the maths along with me: this is not a yardstick for a client project. I built the whole foundation myself, including every wrong turn. Anyone starting on the finished foundation needs a fraction of it.

Mishaps: the list no testimonial ever includes

Completeness is the point here, so all of them, in order:

• The internal zone that was public — the security hole from part 2. Found by our own test from the outside, not by an attacker. Got lucky, changed the process.
• The noise in the reading voice — the odd byte from the Workshop story. Cost an evening of detective work and delivered the best story of the series.
• The over-eager postman: our own mail automation cleared away the confirmation codes an online service was sending us — at which point the service locked us out for hours. Our own automation as the opponent: nobody had that on their list.
• The power cut: the AI machine in the office was dead for a day. No defect, a plug. “Remote switch” has been on the shopping list since.

And the abandonments — started and deliberately buried: an automation toolkit that needed more care than it saved, and a password stopgap that did not hold up to our own standard. That, too, is part of the bill. Whoever never throws anything away has never tried anything.

The return that turns the calculation around

The other side of the ledger is not a saving in francs. It is called reuse: the same platform — mail, calendar, storage, document archive, the agent on top — today carries five entities: two private individuals and three companies. It was built once. Every further entity costs a fraction, because the foundation is standing. On top of that, four channels played from a single machine: this website, two LinkedIn presences, Instagram — and what appears here is produced in two languages, voiced and signed, because the agent carries the grunt work.

The verdict, in one sentence

Around 200 hours and CHF 15,000 — and in return a foundation that carries five entities and gets cheaper with every one you add. This calculation does not work out through saving. It works out through building.

The Sunday question

Which price tag is missing from your own AI calculation — the learning curve, the operations, or the cost of doing nothing?
