Model answer
A north star metric is the single metric that best captures the core value your product delivers to customers, and that predicts sustainable business growth. It aligns the whole company on one direction.
A good one:
- reflects customer value, not just company revenue,
- is a leading indicator of long-term growth,
- is measurable and something teams can influence,
- is simple enough for everyone to understand.
Examples: for a music streaming service, time spent listening; for a team-messaging app, number of teams that send a meaningful number of messages each week; for a marketplace, number of successful transactions.
Teams then break it into input metrics such as activation, frequency and retention, which individual squads can own. Avoid vanity metrics such as page views or sign-ups that can grow without delivering value. Pair the north star with guardrail metrics like quality or support load.
Key points
- One metric that captures the core customer value
- Leading indicator of growth, not a vanity metric
- Break it into input metrics that teams can influence
Likely follow-ups

Common mistakes
