Worked example

If a collaboration product chooses weekly active teams as its North Star Metric, teams track whether acquisition, activation and retention work increases that usage outcome over time.

A North Star Metric is valid when it represents recurring customer value and business growth. Compare it with input metrics such as activation, retention and frequency.

How it works

North Star Metric gives teams a named way to make growth decisions measurable and economically grounded. In the Marketing Refs graph, it links definitions to adjacent metrics, workflows and operating choices instead of leaving the term as isolated vocabulary.
