Definition of AARRR
AARRR - also known as Pirate Metrics - is a framework of five customer lifecycle metrics: Acquisition, Activation, Retention, Referral, and Revenue. Investor Dave McClure coined the term in 2007 as a simple way for startups to structure their customer data and track a user’s journey from first contact through to becoming a loyal, paying customer.
Acquisition is about attracting new users to your product or service. Activation involves ensuring that these users have a positive first experience. Retention focuses on keeping these users engaged over time. Referral is about turning your users into advocates who bring in new users. Finally, Revenue is about monetising these users. By understanding and optimising these five stages, marketers can drive growth and profitability.

AARRR vs other growth frameworks
| Framework | What it measures | Best used for |
|---|---|---|
| AARRR (Pirate Metrics) | Five customer lifecycle stages: Acquisition, Activation, Retention, Referral, Revenue | Diagnosing where users drop off across the full customer lifecycle |
| Customer lifecycle funnel | A linear path from awareness to purchase | Simple, one-directional conversion tracking |
| North Star Metric | One single metric that captures the core value your product delivers | Aligning a whole team around one outcome, rather than five separate stage metrics |
| Growth loops | Compounding cycles where retained and referred users feed back into acquisition | Modelling sustainable, self-reinforcing growth rather than a one-time funnel |
An example of AARRR
Here is an example of how it works:
Acquisition: Growth Method runs a targeted social media campaign to attract potential customers. They offer a free trial of their software to entice people to sign up.
Activation: Once a potential customer signs up for the free trial, Growth Method sends them an engaging welcome email. This email includes a step-by-step guide on how to use the software, encouraging the user to start using it.
Retention: To keep customers engaged and using the software, Growth Method sends regular emails with tips and tricks, updates on new features, and personalised suggestions based on the user’s activity. They also offer excellent customer service to resolve any issues quickly.
Referral: Growth Method introduces a referral programme where existing customers can earn rewards for referring new customers. This encourages users to share their positive experiences with others.
Revenue: Finally, Growth Method converts free trial users into paying customers by demonstrating the value of their software. They offer various pricing plans to suit different needs and budgets, and they send timely reminders towards the end of the free trial period.
How does AARRR work?
AARRR works by guiding marketers through five key metrics: Acquisition, Activation, Retention, Referral, and Revenue. This framework helps marketers understand the customer journey and optimize their marketing strategies. Acquisition involves attracting new users to the product or service. Activation focuses on ensuring the user’s first experience is positive. Retention aims to keep users engaged and returning. Referral encourages satisfied users to recommend the product or service to others. Finally, Revenue focuses on monetizing the user base to generate income. By analyzing these five stages, marketers can identify strengths, weaknesses, and opportunities in their marketing strategy.

About Growth Method
AARRR is a reminder that growth isn’t one number, it’s five - and most teams only ever look closely at one or two of them. Growth Method is the agentic marketing platform for B2B teams: it connects to your analytics stack, tracks each stage of the customer lifecycle, and helps your team (and its AI agents) plan, launch and analyse experiments against whichever AARRR stage is actually holding growth back, rather than guessing.
