North Star Metric

Back to the frameworks catalog

A North Star Metric is one core measure that, if chosen well, shows both the value you deliver to customers and healthy business growth. Amplitude popularized the idea for product teams: instead of ten conflicting dashboards, one number the whole team can align on.

What a good North Star looks like

• It measures customer value, not internal activity. “Stories closed” is not a North Star.
• It leads sustainable growth. Net revenue can lag; the metric should signal earlier.
• It is actionable. Discovery and delivery should be able to move it.
• It has clear inputs. Three to five input metrics usually sit under the North Star.

Examples: Spotify’s time spent listening, Airbnb’s nights booked, Slack’s messages in teams that reached habitual use. Copying someone else’s metric is a mistake; yours should come from your own Jobs To Be Done.

A common mistake

Do not treat the North Star as a substitute for OKRs or KPIs. An OKR is a period goal; KPIs are a set of measures; the North Star is a compass. If the number rises while customers get worse off, change the metric.
