Cohort Cartography
Retention as geography. You leave with plotted curves, a kill-list for rotten events, and a method for talking to finance without inflating a halo metric.
Read the mapRead the ground before you move the product.
System Maphub trains product people to treat App Analytics as terrain: who stays, where the instrumentation lies, and which curve is only a polite average.
Open the flagship syllabus
“The Cohort Cartography term stopped us arguing about a single retention number. We now keep three maps and a list of events we are allowed to kill.”Helen Okoye · product operations, Manchester

Programmes with a visible edge
Each course is a bounded survey. We do not sell a catalogue of tools. We teach how to draw the behaviour of an app so a team can disagree in public, with paper.
Event Taxonomy Clinic
How names age, how properties multiply, and how a warehouse becomes folklore. Built for teams who inherited a schema they can no longer defend.
Enquire by letter
Funnel Integrity
Drop-off that is instrumentation, not intent. You audit a live funnel, mark false cliffs, and write the correction the engineering ticket actually needs.

Why we still say cartography
Dashboards flatten. A map, even a crude one, forces a decision about scale, legend, and what you refuse to plot. That is the discipline we keep at System Maphub: App Analytics as a drawing problem, not a vendor tour.
Students work from their own product where possible. When they cannot, we lend a sanitised dataset from a travel marketplace and a grocery app — enough mess to be honest, not enough to be a case-study costume.
The United Kingdom is our legal home and our calendar. Live rooms run on London time. Recordings exist, but the argument happens in the room.

If your dashboard already looks finished, you probably need a map.
Fees are published. Places are limited by how many live critiques we can actually sit with. Write with the app you are trying to understand.
