The house
A reading room for application behaviour.
We sit in Collier’s End and teach people elsewhere. The work is British in temperament: suspicious of decoration, fond of a dated ledger, unwilling to call a chart a strategy.
Mission
Endpoint Cachecore exists because app analytics has become a vendor tour. Product teams buy a platform, accept the default funnels, and then argue in stand-up about numbers nobody could reconstruct from the event log. We teach the reconstruction.
The house is small on purpose. Directed cohorts stay short enough that Imogen Fairfax can still read every critique. We refuse programmes that would require a teaching assistant to impersonate judgement.
Pedagogy
Write, then defend.
Each session asks for a one-page ledger or a named objection. Slides are allowed only as evidence. If a student cannot explain an identity graph without pointing at a purple bar, we send them back to the event dictionary.
United Kingdom regulation is not an appendix. Consent flags, retention of identifiers, and the ICO’s patience with “product improvement” as a purpose all appear in the first week of Quiet Instrumentation and again whenever a taxonomy gets ambitious.
Community
Alumni, not a feed.
There is no public forum and no streak counter. Alumni may request a second reading of a board paper for twelve months after a directed cohort. That is the community: a slow correspondence, not a Slack full of screenshots.
We host two in-person evenings a year near Hertford when travel is reasonable. Attendance is optional. The work remains the ledger you can email to a sceptical CFO.
The student journey
Most people arrive with a dashboard they distrust and a stakeholder who still quotes it. We begin with a written inventory: events you emit, identities you stitch, and the one decision last quarter that used a number you could not rebuild. If that inventory is empty, we recommend waiting.
Directed students then spend six to eight weeks on a single artefact — usually a retention ledger or a funnel rebuilt from raw events. Self-paced Pulse Desk students receive recorded critiques of other ledgers and a reading list; they do not receive a personal mark.
The journey ends when you can explain a drop-off without blaming “engagement.” Some guests leave earlier, which we prefer to a certificate that pretends otherwise.
