Every Product Needs a North Star Metric: Here's How to Find Yours

Julia Sholtz · Amplitude Free Beginner

The biggest tracking mistake in an MVP is measuring everything and learning nothing. This Amplitude piece walks you through picking one metric that maps to real customer value and finding the early aha moment that predicts whether people stick around, which tells you the few events actually worth tracking. Treat it as a starting point for focus, not a rule: a small product is still learning what matters, so revisit your metric as you go.

  • A good North Star Metric is a leading indicator of value delivered, not a lagging number like monthly revenue.
  • Find the early aha action that predicts retention (the classic example is Facebook users adding seven friends in ten days) and instrument that first.
  • Choosing one metric and a few inputs keeps your tracking small and honest instead of a dashboard nobody reads.
