The growth sequence / our inference

How Edubily's loop likely runs.

Built from the public tactics above. It is a reading of the mechanism, not the brand's internal strategy, and seeing a tactic doesn't prove it caused growth.

Two tests worth running / proposed

What we'd test next.

Recommendations to try, not confirmed strategies. Compare randomly assigned groups within the eligible audience and read the KPI alongside incremental margin.

Test 1

Subscription based on product and consumption

Trigger / audience: Customer re-purchases SKU eligible for subscription
Proposed action: Show how it works and the next subscription delivery
Main KPI: Margin after two renewals per eligible customer
Measurement window: One full purchase/renewal cycle; set duration with historical data before the test

Test 2

Referral with current conditions

Trigger / audience: Satisfied repeat customer; new validated referral campaign
Proposed action: Invite to refer with current reward and correct market
Main KPI: Incremental margin from new referred customers
Measurement window: One full purchase/renewal cycle; set duration with historical data before the test

Evidence limit
