Pirate Metrics (AARRR)
Dave McClure’s five-stage growth framework — Acquisition, Activation, Retention, Referral, Revenue — used to structure funnel dashboards, experiment backlogs, and team ownership. Each stage has its own north-star metric and set of leading indicators; weakness at any single stage caps the whole business. Modern variants (RARRA, for example) reorder the stages to put Retention first, arguing that without retention the other stages leak money.
How Pirate Metrics (AARRR) works in practice
AARRR is most useful when each stage has a single unambiguous metric and a team that owns it. Acquisition is usually top-of-funnel traffic or qualified sign-ups; Activation is the moment a new user hits the aha moment; Retention is whatever repeated-use metric matches the product (weekly active users for consumer, monthly logins for SaaS); Referral is invite-driven sign-ups or NPS-adjacent virality; Revenue is first payment or subscription conversion. Weakness at any stage compounds: cheap acquisition cannot save a product with broken activation, and great activation leaks money if retention collapses after week four. The RARRA reorder (Retention first) exists because founders routinely pour money into acquisition before retention is solved, and end up buying users who churn faster than they arrive.

If your trial-to-paid rate is stuck, there's usually one or two things blocking it — let's find them.
Let's talk →This term sits in the SaaS category, which means it is most useful when evaluating subscription growth, activation, retention, expansion, and revenue efficiency. The goal is not to memorize the label. The goal is to know when it should change a decision, a page, a campaign, or a measurement setup.

The single metric a business treats as its clearest indicator of sustainable value creation.
The percentage of new users who reach a defined "aha moment" — the point where they first experience the core value of the product. Low activation rate is frequently the highest-impact growth lever for early-stage SaaS products.
The percentage of customers who cancel or do not renew within a given period. High churn erodes MRR growth and increases CAC payback period, making retention optimisation as important as acquisition for sustainable growth.
Mapping and measuring the sequential steps users take toward a conversion goal. Funnel analysis pinpoints where users drop off so optimisation effort is directed at the highest-impact bottlenecks.
