North Star Metric
The single metric that best captures the core value a product delivers to its customers.
Definition
A North Star Metric (NSM) is the single metric that best captures the core value a product delivers to its customers — chosen so that growing it reliably drives sustainable, customer-centric business growth. Coined by Sean Ellis, the concept gives an entire organization one shared, leading indicator that aligns teams around delivering real customer value rather than chasing disconnected outputs or vanity metrics. A good North Star expresses value, reflects engaged usage, and predicts future revenue — for example, Airbnb's 'nights booked' or Amplitude's 'weekly querying users.'
Examples
Airbnb: nights booked (value for both guests and hosts)
Amplitude: weekly querying users (customers getting value at least weekly)
Spotify: time spent listening; Slack: messages sent within active teams
How AdSights helps you track North Star Metric
A North Star Metric only grows when acquisition brings in users who actually realize value — not just users who sign up. AdSights connects creative and audience performance to value-aligned outcomes, helping teams see which campaigns drive sign-ups that go on to contribute to the North Star versus those that pad the top of the funnel. That keeps acquisition honest: optimizing creative toward the value the North Star measures, not vanity reach.
