What is North Star Metric?
A North Star Metric is the single measure that best captures the core value a product delivers to its customers. Teams use it to align decisions across functions: if an initiative cannot plausibly move the North Star, its priority is questioned. It is usually supported by a small set of input metrics.

In more depth
A good North Star Metric sits at the intersection of customer value and business value — it rises only when customers are genuinely getting what they came for, and sustained growth in it predicts revenue. That distinguishes it from vanity measures such as registered accounts or page views, which can climb while the product fails. Because a single number cannot be acted on directly, teams break the North Star into input metrics — the two to four measurable behaviours that drive it — and assign ownership of those inputs to specific teams.
Why it matters
Without a shared definition of success, teams optimise their own local measures and the product drifts. A North Star Metric gives every function — product, design, engineering, marketing — one test for whether work matters, which simplifies prioritisation debates and makes trade-offs explicit. It also protects against chasing growth that does not reflect real customer value.
A product example
A collaborative document tool could choose weekly active editing teams as its North Star: it counts only teams genuinely using the core product together, not solo sign-ups or dormant accounts. Input metrics might be new teams reaching their first shared document, documents edited per team per week, and invited colleagues who activate.
