AARRR: The User Journey Without Illusions. How to Find the 'Hole' Where Product Value is Lost

Diving into the AARRR framework (Pirate Metrics) as a powerful tool for diagnosing product problems, focusing on where users stop getting value.

AARRR: The User Journey Without Illusions. How to Find the 'Hole' Where Product Value is Lost

In the race for growth, product teams often get stuck on acquiring new users, forgetting the main thing: growth is not acquisition, growth is retaining value over time. If your product is 'leaking,' endless marketing investments will just be 'pouring gasoline into a car with a leaky tank'—noisy, expensive, but with no real progress.

This is where the AARRR framework, also known as 'Pirate Metrics,' comes to the rescue. It's not just a funnel, but a powerful feedback system that allows you to locate where value is lost for the user and understand why it's happening.

Why AARRR? Why Growth Isn't Cured by New Features

Often, teams make two critical mistakes:

  1. They treat Acquisition when Retention is leaking. This leads to an endless cycle of marketing spend with no real effect.
  2. They treat the symptom instead of the mechanism. For example, 'people aren't buying → let's add a new paywall,' when the real problem is 'people aren't repeating the value action → they have nothing to buy.'

AARRR is needed to clearly understand at which step the user stops receiving value and to focus efforts on fixing that 'hole'.

What is AARRR? A Feedback System

AARRR (Pirate Metrics) is five stages of the user journey that form a feedback loop:

  1. Acquisition: How do target users learn about the product and get inside?

    • Not just traffic, but: the right people in the right situation.
    • Example: A person is looking for a solution to problem X, finds your product, and signs up.

  2. Activation: Did the user reach the first moment of value ('Aha, it works!')?

    • Not just registration, but: getting the first result.
    • Example: In a B2B SaaS, a user creates their first project and sees the task is assigned.

  3. Retention: Does the user come back for the same result?

    • Not just opening the app, but: repeating the value-delivering action.
    • Example: A team returns to the SaaS every week and manages tasks.

  4. Referral: Does the user bring others because they genuinely want/can?

    • Not just a 'share' button, but: motive + moment + low friction.
    • Example: A user invites a colleague because they need to collaborate.

  5. Revenue: Is the user willing to exchange money to continue/enhance the value?

    • Not a goal in itself, but: proof that the value holds.
    • Example: A user hits the project limit and pays for a subscription.

How to Use AARRR: Rule #0 — Agree on Value

The main stumbling block in working with AARRR is the lack of a clear definition of 'value.' If you haven't defined a value-event, AARRR will turn into 'we measure everything.'

Value-event — is one specific user action that means: 'Yes, the product has delivered on its promise to the user.'

Criteria for a good value-event:

  1. It's related to the core value of the product.
  2. It's repeatable (the user might want to do it again).
  3. It's measurable.
  4. It's not 'preparation' (like registration), but a result.

Examples of Value-event:

  • Notion: A document is created and saved.
  • Duolingo: A lesson is completed.
  • Spotify: A track is listened to for ≥ X seconds.
  • B2B SaaS: A report is created and used.

The main diagnostic question: 'If the user performed this action, did we truly make their life better?' If you have doubts, it's not a value-event.

Common Mistakes

  • One value-event for everything: Different segments have different values, and therefore, different value-events.
  • Too 'early' a value-event: 'Clicked a button' ≠ 'got a result'.
  • Counting retention without value: This is self-deception, not analytics.

Rule #1: Retention is the Main Sign of Life

It is Retention that answers the question: is value retained over time or does it decay? Therefore, diagnostics always start with Retention, not Acquisition.

Rule #2: Activation and Retention Must Be Linked by the Same value-event

  • Activation: the first value-event.
  • Retention: repeating the value-event within a time window (D7/D14/D30 or W1/W4, depending on the domain).

This way, you are measuring precisely value, not just activity.

By using AARRR as a feedback system and focusing on the value-event, you will get a real, not illusory, user journey, be able to pinpoint the 'holes' where value is lost, and make informed decisions for sustainable growth.
