The identity week assumed more warehouse access than we had. The sandbox got us through. I still would not call the homework gentle.

Flagship · nine weeks
Grid Instrumentation
The Plot Room. You will leave with an event dictionary a designer can argue with, a cohort window that matches how people actually return, and a weekly plot your engineering lead can sign. You will not leave with a vendor badge.
Outcomes
What the nine weeks are for
- A spoken event dictionary of no more than forty verbs, each a behaviour a person could refuse.
- A written identity policy: when you stitch, when you refuse, and how historic cohorts survive a login rewrite.
- Isoline retention that uses the product’s real rhythm, not a slide template’s D7.
- One funnel that contains only chosen steps, with struck vanity documented.
- A weekly plot: one claim, one limitation, one check for the following Monday.
Modules
The term, week by week
-
Weeks I–II
Naming the ground
You arrive with an export or the sandbox. We strike events that describe screens, not actions. The homework is a dictionary read aloud to someone who does not work in analytics. If they cannot hear a person in the verbs, you rewrite.
-
Weeks III–IV
Identity seams
Anonymous to known, web to app, guest to account. You will write a seam policy and a paragraph on what you will not stitch. Several students discover here that their historic D7 is a fiction of changing IDs.
-
Weeks V–VI
Windows and isolines
Return rhythm, not calendar folklore. Travel, grocery, meditation, and B2B tools are given different windows on purpose. You present two curves and explain why a third would be dishonest.
-
Weeks VII–VIII
Surveying the drop
Funnels rebuilt from chosen steps. You strike at least one beloved vanity step in critique. The accompanying note must say what conversion is now not allowed to mean.
-
Week IX
The weekly plot
A one-page Monday note presented to the cohort. Isolde marks the claim, the limitation, and whether engineering could sign it. This is the finish; there is no exam.
Instructor
Isolde Venn
Isolde ran measurement at a Hastings travel product until the dashboards could not survive an engineering question. She opened Index Mapgrid in 2017 and still marks every Plot Room weekly plot herself. She does not consult on warehouse build-outs; students who need that are sent elsewhere.
Informational fee
Plot Room seat
The live cohort is listed at £2,150 for nine weeks, including fourteen hours of critique. Field Sheet, the written plates alone, is £480. Survey Licence mentoring is a separate retainer. There is no checkout here; fees and the desk are how seats are discussed.
A real limit
What we will not pretend
Grid Instrumentation does not include Mixpanel, Amplitude, or GA4 certification. We do not provision a production analytics stack, and we do not write tracking code for your release train. If your shop cannot export events, you work the sandbox; that is a genuine constraint, not a marketing footnote, and it shows up in homework that assumes warehouse access you may not have.
From the Plot Room
★★★★☆
Dictionary week killed session_start as a KPI. Quiet dashboards. Four stars because August scheduling slipped a critique.
Platform note · 4/5 · March intake
Week nine’s plot is the thing I still run. Shorter than our old pack. The growth lead stopped asking for a third funnel.

Questions we actually get
FAQ
Do I need SQL?
Comfort with a CSV and a sceptical eye is enough. Identity week is easier if someone on your team can join tables; if not, the sandbox is already joined, which is a limitation we state in week one rather than discovering in week four.
Can I bring a live consumer app?
Yes, if you may export. We never ask for production credentials. If legal will not let events leave the building, use the sandbox and translate the dictionary back to your stack after the term.
Is this a Mixpanel course?
No. That is a real limitation, not a positioning trick. We will look at screenshots from whichever tool you use, and we will refuse to mark a dashboard that cannot be explained in sentences.
What if I miss a critique?
Recordings exist for two of the seven live sessions. The others are argument and do not record well. Miss more than two and we will talk about deferring rather than pretending you sat the term.
How do refunds work?
The refund plate is the contract. In short: a full refund before week two’s critique; partial after that; Field Sheet is not refundable once the plates are issued.
