Acquisition Loops

Pourquoi : You pick which loop to build first, such as referral or content, and estimate how it compounds, so the roadmap is not a list of one-off campaigns.

Channel Mix Optimization

Pourquoi : You rebalance budget between paid, organic and referral using CAC and saturation, and can justify moving money away from a channel the team likes.

Aha Moment & Activation Metrics

Pourquoi : You find the action that separates retained from churned users and set it as the activation metric, so onboarding is optimized toward it.

Retention Curves & Cohort Analysis

Pourquoi : You tell a curve that flattens from one that keeps falling and locate which cohort broke, so an intervention targets the cause of churn.

A/B Testing Rigor

Pourquoi : You check sample ratio mismatch and refuse to stop a test early on a good-looking day, so a launched variant is a real win and not noise.

Statistical Power & Bayesian vs Frequentist

Pourquoi : Before starting, you size the sample and say whether the traffic can detect the expected lift, so you avoid running tests that can never conclude.
