Retention Cartography
How to draw a retention curve that a designer, a marketer, and a sceptic can all inhabit.
Thirsk · App analytics studio
The chart is not the argument.
Workspace Nodehub teaches product people to sit with instrumentation until it yields a sentence they can defend in a Tuesday review.

Flagship programme
Product Signal Studio
Six modules that begin with taxonomy and end with a board pack you would actually send. Amplitude and Mixpanel appear as working benches, not as religions. SQL is present, but it is never the point.
The studio is paced for people who already own a live app — growth leads, product managers, and the analyst who has been asked, once too often, to “just add a north star.”

Close reading, then a claim.
-
Name the thing the product did
Events are treated as vocabulary. If two teams cannot share a sentence about “activated,” the chart is already lying. We spend more time on naming than on colour palettes.
-
Watch the cohort, not the headline
Retention Cartography sits in every programme. You will leave able to explain a curve to a designer who has never opened a warehouse.

Write the sentence the board needs
The last week is not a certificate. It is a short paper: what moved, what did not, and which experiment you will not run again.

Shorter rooms, same standard.
Event Taxonomy Lab
A working method for properties that still make sense after the next reorg.
Board Pack Analytics
Twelve slides, no vanity metrics, and a voice that does not apologise for uncertainty.
From the journal
Why DAU is a lazy north star
Daily active users flatten almost every interesting argument about a product. The essay walks through three UK apps that looked “healthy” on DAU while activation quietly stalled in week two.

Notes, not slogans.
“The Event Taxonomy Lab stopped us from shipping a sixth version of ‘signup_success’. We still argue, but we argue about meaning now, not about column names.”
“Week three of Product Signal Studio assumed more warehouse fluency than the syllabus implied. I caught up, but I would warn a colleague who has never written a join.”
“Board Pack Analytics taught me to put the reservation in slide two instead of burying it. Our CFO has been oddly calmer since.”
