Retention Geometry
Four weeks on cohort curves, resurrection, and the temptation to smooth a cliff with a friendly average.
Isle of Man studio · United Kingdom
Eleven seats in a live cohort
App analytics, taught as composition
The event stream is a document. Most teams never learn to read it.
Consolevectorgrid trains product and data people to write taxonomies, defend retention charts, and stop treating vendor screens as a strategy.

“The taxonomy week forced us to retire 40 events that had been reporting ‘engagement’ while measuring button paint. I still dislike how slow the governance ritual is, but the numbers finally match the product we ship.”Priya Menon · Principal PM, Leeds fintech · Event Taxonomy Atelier
Flagship
Event Taxonomy Atelier
Our longest programme is not a tour of Mixpanel or Amplitude. It is an editorial studio: naming law, property dictionaries, identity stitching without theatre, and a live critique of the student’s own event catalogue.
Cohorts stay at eleven people so every dictionary is read aloud. The fee is published on the fees page; there is no checkout on this site.

Four corrections we make before a dashboard is allowed to exist
-
Names before charts
App analytics collapses when
cta_clickandHeroTappedboth claim to be the same moment. We teach a naming grammar that a new hire can extend without a meeting. -
Windows that admit their bias
A seven-day retention curve is a different essay from a twenty-eight-day one. Students leave able to label the window in the chart title, not bury it in a tooltip.
-
Identity without mythology
Anonymous-to-known stitching is taught as a lossy join, not a personality. We document what is dropped when a user resets an identifier on iOS.
-
Warehouse as the court of appeal
The console is a drafting table. When a board number is challenged, the warehouse query is the document we file. The custom cohort intelligence page explains how we keep those two rooms in conversation.
Also in the catalogue
Shorter programmes for teams already mid-instrumentation
Funnel Cartography
How to draw a path that matches the app’s actual screens, including the dead ends product prefers not to mention.
Session Replay Literacy
Using replay as evidence, not as a peep-show. Privacy constraints as they apply in the United Kingdom.
From the studio ledger
Voices, not slogans
I came for dashboards and spent the first fortnight arguing about verbs. The Event Taxonomy Atelier is closer to copy-editing than to a vendor certification, which I did not expect and still find slightly maddening. Our activation report is shorter now, and the engineering ticket queue is quieter.

Warehouse-Native Measurement finally explained why our Amplitude number and our BigQuery number were cousins, not twins.

Funnel Cartography was the right length. Retention Geometry would have been more useful to us a year earlier; we already had the scars.

Write before you enrol
We answer within two working days. Bring a screenshot of the messiest event in your catalogue; it is a better introduction than a slide deck.
