A North Star Metric (NSM) is the single, most important metric that best captures the core value your product or service delivers to customers. It guides teams to focus on long-term growth and aligns everyone around what matters most.

Examples:

  • For an e-commerce site: Number of purchases per month
  • For a social platform: Daily active users
  • For a SaaS product: Number of active subscriptions

Choosing the right NSM helps prioritize efforts and measure true progress. It should be actionable, measurable, and directly tied to customer value.
