Why Some Products Thrive While Others Struggle to Stay Relevant

A small startup, eager to disrupt its industry, prided itself on shipping new features every two weeks. Investors were impressed by the pace, and early adopters were excited. But over time, something strange happened—growth stagnated. Engagement plateaued. The churn rate climbed.

Their mistake? They were measuring output, not outcomes.

According to Amplitude, 76% of product teams track engagement, but only 40% tie their key metrics to business impact.

Without a clear North Star Metric, efforts can feel productive but fail to drive meaningful growth.

What is a North Star Metric?

Your NSM is the single most important indicator of your product’s success. It ties business value, customer value, and product strategy into one meaningful goal.

A bad NSM focuses on vanity metrics:

• Number of features shipped

• Total signups (without retention)

• App downloads (without engagement)

A good NSM answers:

• What core action do successful users take?

• How does this metric drive long-term business growth?

• Would improving this metric naturally improve our product’s value?

Examples of Simple Yet Effective North Star Metrics

Let’s look at how different types of products might define their NSM.

A Fitness App

• Bad NSM: Number of total app downloads

• Good NSM: Percentage of users who complete at least three workouts in their first week

• Why? A user who completes three workouts is far more likely to stick with the app long term.

A Marketplace for Freelancers

• Bad NSM: Number of freelancer signups

• Good NSM: Percentage of freelancers who complete their first paid project within 30 days

• Why? A freelancer who gets paid quickly is more likely to stay engaged on the platform.

A Meal Kit Subscription Service

• Bad NSM: Number of subscriptions started

• Good NSM: Percentage of users who reorder at least twice within the first two months

• Why? A second order shows that the customer sees long-term value in the service.

How to Define Your Product’s North Star Metric

• Identify Your Core Value Moment → What’s the key action that signals a user is finding value?

• Make It Measurable → Can you track and influence it over time?

• Tie It to Business Growth → Will improving this metric naturally boost revenue, retention, or referrals or acquisition?

Why Many Teams Fail at NSMs

Common Mistake #1: Chasing Revenue Instead of Retention

Example: An Edtech platform focused on total course enrolments. But only 20% of students completed a course—leading to low renewals and referrals. Their real NSM should’ve been “percentage of students completing at least one course.”

Common Mistake #2: Focusing on Activity Instead of Outcomes

Example: A no-code website builder celebrated 100K new users, but only 3% actually published a live website. Their real NSM should’ve been “percentage of users with a published site with 5+ pages.”

Your North Star Metric isn’t just a number—it’s a mindset shift. It forces you to think beyond short-term wins and focus on long-term product success.
