Growth Experiment System — From Idea to Decision

Do not start from a list of hacks. Start from the constrained stage of the funnel and run the smallest experiment that can change a decision.

1. Define the growth model

Record:

ICP | value event | acquisition source | activation event | retained-use event | paid event | referral event

Build the baseline funnel by cohort. For consumer products include D1/D7/D30 retention; for B2B include qualified pipeline, sales cycle and collected revenue. If the events are not instrumented, instrumentation is experiment zero.

2. Find the constraint
