What are pirate metrics (AARRR)?
Pirate metrics, or AARRR, are a framework that splits the customer lifecycle into five stages: acquisition, activation, retention, referral and revenue. Each stage gets its own metric, so a team can see where people drop off and which stage to fix first.
What does AARRR stand for?
AARRR stands for acquisition, activation, retention, referral and revenue. Investor Dave McClure introduced the framework in 2007, and the acronym read aloud ("aarrr") gave it the pirate-metrics nickname.
| Stage | The question it answers | Example metric |
|---|---|---|
| Acquisition | Are the right people finding us? | Sign-ups from target accounts, by channel |
| Activation | Do new users get value in their first session or week? | Activation rate within 14 days |
| Retention | Do they keep coming back? | Users still active in week 8, by cohort |
| Referral | Do they bring others in? | Invites sent and accepted per active account |
| Revenue | Do they pay, and pay more over time? | Conversion to paid, expansion revenue |
Each stage needs one defined event and one owner. Without that, AARRR is a diagram on a slide.
How do you use the AARRR framework?
Lay the stages out as a funnel for one cohort, measure the conversion from each stage to the next, and fix the stage that loses the most people relative to what you'd expect for your product.
Worked example for one month's cohort:
- 10,000 people visit and 1,000 sign up (acquisition: 10%)
- 400 of the 1,000 reach the activation event within 14 days (activation: 40%)
- 200 of those 400 are still active at week 8 (retention: 50%)
- 40 of the retained users invite a colleague who joins (referral: 20% of retained users)
- 60 of the 1,000 sign-ups become paying customers (revenue: 6% of sign-ups)
The tempting move is to buy more traffic. The better one is usually to fix activation or retention first. Every extra point there improves the return on every visitor you already pay for, while more acquisition into a leaky stage mostly buys more churn. That's why some teams reorder the framework to start with retention.
Two cautions. Define each stage by a value event, not a page view or login. And benchmark against your own earlier cohorts, because conversion between stages depends on your price point, sales motion and how much setup the product needs.
Where does the product move each pirate metric?
Marketing owns most of acquisition. The product owns most of the rest:
- Activation moves when setup gets out of the way of the first result.
- Retention moves when the recurring job is easy to do again and new needs are met inside the product.
- Referral moves when collaboration is part of the work (sharing, approvals, invites).
- Revenue moves when users reach the value of a paid feature before they reach its paywall.
An in-product agent works on the middle stages directly. When a new user can ask for a setup step and the agent does it with them, more of them can reach activation in the first session. Foldspace's Product Agent does that work in the product, and Conversational Analytics maps each request to its intent, so the team sees which conversations went unresolved at the stages where users ask the agent for something.
