This walks you through the AARRR framework (Acquisition, Activation, Retention, Referral, Revenue) to diagnose where your growth is actually stuck. It's Dave McClure's pirate metrics model, organized as tables of key metrics and tactics per stage, plus pointers to related skills for deeper work. Use it when you need to figure out if your problem is getting users in the door, getting them to their aha moment, or keeping them around. The cohort analysis emphasis is smart since aggregate numbers hide what's really happening. It won't run campaigns for you, but it'll help you see which stage is bleeding users so you stop optimizing the wrong thing.
