What problem does it solve? Teams often chase vanity metrics like total signups while retention quietly collapses, wasting acquisition budget on a leaky bucket. This Skill diagnoses the real growth bottleneck by AARRR stage, designs compounding growth loops instead of one-way funnels, and prioritizes experiments with defined success thresholds. ## Core Features & Use Cases - Retention and Churn Diagnosis: Runs cohort-based retention analysis, names the bottleneck stage, and designs dunning sequences, save offers, and cancellation flows before any acquisition spend. - Growth Loop and Launch Strategy: Designs viral, engagement, and community loops with defined K-factor mechanics, plus channel portfolio strategy using the ORB framework and five-phase launch plans. - Experiment Prioritization with Clear Ownership: Sets success thresholds before running experiments and routes execution to the correct owner skill for copy, paid media, lifecycle, distribution, or measurement. - Use Case: A SaaS team with 10,000 signups but only 800 active users after 30 days gets a cohort retention diagnosis, a named Retention bottleneck, and a retention-first experiment plan instead of a bigger ad budget. ## Quick Start Ask the growth strategist to diagnose why users are churning and propose a prioritized experiment plan with success thresholds.
