Holdout Design for Product Retention
Six modules from cohort construction to a signed stop rule. Built for PMs and analysts who are tired of Day-7 theatre. Includes holiday-calendar work specific to Thailand.
Programmes
Each programme assumes you can already query an events table. We teach the experimental layer on top: how return is defined, how holdouts leak, and how a memo gets a kill decision through a sceptical room.

Rename the events that actually define return. We walk a tracking plan until “open app” is no longer pretending to be a north star, then wire a minimum viable holdout flag.
Offered as a four-session remote block. Write to the studio for the next window.
Push, in-app, and email tests that respect a holdout instead of drowning it. Quiet-hours norms in Thailand, fatigue guardrails, and a module on what not to randomise when CRM tools share audiences.
When the unit is a listing, a store, or a rider zone — not a tidy user id. Built for classifieds, grocery, and two-sided Bangkok marketplaces whose leakage stories are geographical.
Fees are informational. There is no checkout on this site. Compare seating types or ask which bench fits your volume.
