Windows before colours
A cohort is a decision about time. We spend an indecent amount of attention on when the clock starts, and almost none on palette.
Autumn studio · Gulworthy & remote
The metric must be able to sit in a room without flinching.
Workspace Cachehub is a small teaching house for App Analytics. We work with product operators who already have dashboards, and still cannot quite say what last week meant. The studio is not a tool clinic. It is a method for reading product numbers as if a sceptical director were already in the chair.

Reading Product Signal
Most analytics programmes begin with a tour of charts. This one begins with a sentence you would be willing to put in writing: what changed, for whom, over which window, and what you will not claim. Over six weeks you rebuild a working reading of activation, retention, and a single revenue event from your own product — or from a carefully licensed sample app if you cannot bring data.
The cohort meets twice a week from Gulworthy over a quiet video line, with one in-person table in late October for those who can travel. Recordings exist, but the work is done in the live hours. If you need a fully asynchronous course, this is the wrong house.
“I arrived with a retention chart I had shown three times and still could not explain. The Tuesday review made me throw out the seven-day window I had copied from a blog. The new map is slower to draw and much harder to argue with. I still dislike the homework volume.”
House rules
How we refuse to teach App Analytics
The studio is small on purpose. We do not sell a certificate you can paste onto a profile, and we do not promise a lift in a north-star metric. What we do promise is a sharper refusal: you will leave knowing which numbers are costume and which will survive a follow-up question.
One claim per page
If a slide needs three caveats, it is not a slide. It is a draft. The studio trains you to cut until a sentence can stand.
Tools are rented, method is kept
We demonstrate in commonly used product analytics suites. The method travels when the contract ends. The screenshots do not.

Shorter programmes
The flagship is the spine. These shorter desks exist for teams that already know where it hurts.
Retention Cartography
Build a retention map that names drop-off by first-week behaviour rather than by calendar luck.

Store Page Forensics
Read listing conversion, custom store pages, and review velocity without treating the store as a slot machine.

Experiment Hygiene
Stop leaking interpretation through peeking, overlapping tests, and holdouts that were never holdouts.

Write before you book a seat
If you are unsure whether the flagship is the right desk, send a short note describing the decision you cannot currently defend. We reply within two working days. The studio does not take walk-in enrolments.
