Cohort Signal Architecture
Leakage-safe cohorts, event contracts, holdouts, decay curves, and the monthly signal board. This is the full desk.

Courses
Choose the artefact you need to leave with.
Every programme produces something you can put in front of ops: a cohort contract, a quiet-hour overlay, a reactivation holdout, or an attribution memo. Tuition is on the pricing page and is informational only.
Quiet-Hour Calibration Lab
Map send fatigue against local evening peaks in Thailand, split staff vs household audiences when the CRM already has a badge, and write a suppression rule you can defend.
No dedicated detail page — enquire via contact and we will send the lab brief.
Reactivation Lift Studio
Design a win-back holdout that ignores celebrity bursts and brand TV, then report lift as repurchase — not as “reactivated opens.”
Runs after Cohort Signal Architecture or an equivalent contract review.
Journey Attribution for CRM Teams
Separate retention from reactivation when both series fire in the same week. Includes a memo template finance has actually marked up in past cohorts.
Assumes you can export a 90-day send log. Messy names slow week one; that is expected.
