What is a North Star metric? Choosing the right one for your startup

A North Star metric is the single metric that best captures the core value your product delivers and best predicts long-term growth. It points everyone on the team the same way.

Why one metric?

Startups can track dozens of metrics, but if every team chases a different one, effort scatters. A North Star makes priorities and decisions easier. For all metrics, see our startup metrics guide.

What makes a good North Star

• Reflects customer value: rises as customers benefit.
• Predicts revenue: correlates with long-term revenue.
• Measurable and understood: everyone knows what it means.
• Teams can move it: product, marketing and support can contribute.
• Not a vanity metric: avoid totals such as sign-ups or page views that can rise without value.

Examples by model

• Collaboration SaaS: weekly active teams
• Marketplace: completed transactions or volume; see our marketplace guide
• Consumer app: weekly actives performing the core action
• E-commerce: repeat customers; see our e-commerce guide
• Learning platform: lessons completed or learning hours

Input metrics

You cannot manage the North Star directly; define the inputs that drive it:

• New user activation
• Frequency of use
• Retention
• Depth of use (features used)

Each team can own an input. Link goals to them with OKRs.

How to choose

1. Write the core value customers get in one sentence.
2. Find the action that marks that value being delivered.
3. Define the metric measuring it and check its link to revenue and retention in past data.
4. Share it with the team and report it regularly.

Common mistakes

• Choosing revenue itself (it measures the outcome, not the value)
• Choosing vanity metrics
• Changing the metric often

Conclusion

A well-chosen North Star channels the team's energy into customer value. To measure what moves it, see our A/B testing guide.
