North Star Metric
The single measure that best captures the value customers get from a product, used to align teams that would otherwise optimise conflicting numbers.
Growth & MetricsA good north star tracks delivered value, not activity: messages successfully sent rather than logins, nights booked rather than searches, batches processed rather than page views. The test is whether the number can only go up when customers are genuinely better off. Vanity metrics fail it — you can raise signups with a misleading ad and raise sessions with a broken layout.
Its function is organisational. One number stops marketing optimising traffic while product optimises depth and support optimises ticket closure. It is not the only metric you watch: it needs guardrails such as churn and satisfaction, because any single number can be gamed if it is the only one anybody is judged on.
In practice
A learning app used daily active users as its north star, and a streak notification pushed DAU up 20%. Before: the team celebrated. After adding 'lessons completed per active week', it turned out the extra sessions were users opening the app to dismiss the notification. The metric moved to completed lessons. The catch — the new number looked far worse at first.

Frequently Asked Questions
Can a company have more than one north star?
One per product or business line, at most. The whole point is to resolve conflicting priorities; two north stars for the same team reintroduces the conflict the metric was supposed to settle.
What is a good north star for a marketplace?
Something that requires both sides to succeed — completed transactions, or nights booked — rather than listings or visitors. Single-sided metrics let you look healthy while the other side of the market starves.
