Why teams enroll

Stop arguing from dashboard screenshots.

Most personalization debates fail because event names drift, segments mix intent with device quirks, and “lift” ignores who never saw the treatment. We teach the measurement layer that sits beside your recommender — not another slide deck on ML theory.

How we teach
01

Signal contracts

Name events once, version them, and catch silent breaks before a release weekend.

02

Holdout craft

Design exclusions that stay honest when feature flags flip mid-cohort.

03

Narrative for stakeholders

Translate confidence intervals into decisions product leads will actually fund.

From Bangkok desks to remote pods

Alumni keep a shared language after the cohort ends.

Graduates leave with templates for experiment briefs, a veto list for vanity charts, and a peer channel that still trades holdout war stories. We host office hours across Thailand time zones so product analysts and mobile leads can join the same thread.

“The module on mid-flag holdouts forced us to redo our Q2 ranking test. Painful for a week, then the board stopped asking for screenshots.”
