Strategies: Growth Funnel (AARRR)
Guides growth using the AARRR framework (Pirate Metrics)—five stages of the customer lifecycle. Created by Dave McClure (500 Startups) to focus on actionable metrics over vanity metrics. Use this skill when diagnosing growth bottlenecks, prioritizing improvements, or aligning product, marketing, and customer success.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
AARRR Framework
| Stage | Question | Key metrics |
|---|---|---|
| Acquisition | How do users discover you? | CAC, CPA, conversion by source |
| Activation | Do users reach "aha moment"? | Activation rate, time-to-first-value |
| Retention | Do users return? | D1/D7/D30 retention, churn |
| Referral | Do users recommend? | Referral rate, NPS, viral coefficient |
| Revenue | Do users pay? | Conversion rate, ARPU, LTV |
Principle: Define behavior-based events per stage; analyze by cohort. Quality over volume—channels bringing fewer but more activated users often outperform.
