North star metric
north star MEH-trik
The single metric that best captures the core value a product delivers to its customers.
A north star metric is the one number that best represents the value your product delivers. It aligns the entire company around a single measure of success. If this metric grows, the business is healthy. If it declines, something is wrong.
For Spotify, the north star is time spent listening. For Airbnb, it is nights booked. For Slack, it is messages sent. Each metric captures whether users are getting value from the product. Revenue is a lagging indicator of value delivered. The north star metric is a leading indicator.
Choosing the right north star is critical. It must correlate with revenue (if it goes up, revenue follows), reflect customer value (users getting more from the product), and be influenced by the product team's work (not just external factors). It often relates closely to your activation event and retention curve.
Examples
A developer platform chooses its north star.
They consider three candidates: signups, deployments, and active projects. They choose 'weekly active projects' because it correlates best with retention and expansion. A user who has active projects is getting value. Signups without active projects are vanity.
A company aligns teams around the north star.
North star: weekly active teams. Marketing focuses on acquiring teams likely to activate. Product focuses on reducing time to first team project. Customer success focuses on expanding active teams within accounts. Everyone pushes the same number.
A north star metric declines and triggers investigation.
Weekly active projects drop 10% over two months. The team investigates: onboarding completion rate has not changed, but project retention has. They discover a bug in the deployment pipeline causing failures. Fixing it restores the north star.

Frequently asked questions
Should a company have only one north star metric?
Ideally yes. The power of a north star is focus. Multiple north stars defeat the purpose. However, the north star can have 2-3 supporting metrics (called input metrics) that drive it. These create a small dashboard, not a single number.
Can the north star metric change?
Yes. As the business evolves, the metric that best captures value delivery may change. A pre-PMF startup might focus on activation rate. A mature company might focus on expansion revenue. Revisit your north star annually.
