pirate metrics

Definition

The AARRR framework measuring Acquisition, Activation, Retention, Referral, and Revenue—the key metrics for growth-stage startups. Named because AARRR sounds like a pirate, which is somehow still funny to founders.

Example Usage

Our growth team obsessively tracked pirate metrics, discovering that our activation rate was killing overall conversion.

Origin

Coined by Dave McClure of 500 Startups around 2007

Fun Fact

Despite the playful name, optimizing pirate metrics is serious business—improving just one can dramatically impact company valuation.
