Pirate Metrics (AARRR)
Pirate metrics is a framework that organizes startup growth into five stages: Acquisition, Activation, Retention, Revenue, and Referral (AARRR). It provides a structured way to identify the biggest growth bottleneck and focus optimization efforts.
Examples
A SaaS startup maps its funnel using AARRR and discovers that retention is the weakest stage, redirecting resources from acquisition to onboarding improvements.
Best Practices
Measure each AARRR stage independently, focus on the stage with the largest drop-off first, and establish baseline metrics before running optimization experiments.
