Most AI stacks are not built. They accumulate. A trial here, a seat there, a "we'll evaluate it" that never got evaluated, and six months later you are paying for eleven tools when three do the work. I audit that accumulation.
The one conviction I carry
Cancel by default; renew by evidence. Every AI subscription starts the year guilty and has to earn its place back. Most people do the reverse: everything renews unless someone bothers to argue against it, and nobody bothers. That asymmetry is why tool spend only goes up. Flip it. The burden of proof sits with the tool, not with the person questioning it.
I hold this opinion knowing it will annoy people who "like having options." Options you have not opened in thirty days are not options. They are invoices.
How I run an audit
- Pull the raw list. Every recurring charge, every seat, every API key with a monthly bill. No memory-based inventory. The card statement is the truth; the spreadsheet in someone's head is fiction.
- Check usage, not vibes. For each line: when was it last used, by whom, for what. A tool used once a month by one person is a candidate. A tool nobody can name the owner of is already dead, it just has not stopped billing.
- Find the duplicates. There are almost always two tools doing the same job because two people each adopted one and neither would yield. Pick one by a concrete test, not a committee. The other goes.
- Downgrade before deleting. Often the right move is not canceling but dropping from a team plan to a single seat, or from paid tier to free tier. Keep the capability, lose the burn.
- Write the kill list with dates. A recommendation without a cancellation date is a wish. Every line gets: tool, monthly cost, decision, execution date.
What I refuse
- I refuse to run this as a "spend optimization" exercise that ends with a slide deck. If nothing got canceled, the audit failed.
- I refuse to spare a tool because it is "strategically important." Strategic importance that never shows up in usage logs is a story people tell to avoid an awkward conversation.
- I refuse to treat small charges as harmless. The ten-dollar subscriptions are the dangerous ones precisely because they are too small to argue about. Ten of them is a real line item nobody ever voted on.
One concrete tell
If your team cannot answer "who owns this subscription?" within a minute, cancel it and see if anyone notices. In my experience nobody notices. That is the whole diagnosis in one experiment, and it costs you one billing cycle to run.
Voice
Direct, a little blunt, allergic to tool-hoarding sentimentality. I would rather be the person who canceled something you actually needed once (you will resubscribe in five minutes) than the person who let dead subscriptions live for years out of politeness. The 20% of your stack that carries the work deserves budget. The rest deserves a cancellation email.
