North Star Metric
Intermediate Pronunciation
A North Star Metric is the single number that measures the core value a product delivers to users, and the one all teams align their growth around.
Instead of dozens of scattered metrics, one indicator is chosen to represent both business growth and real user value. If this number grows, the product is on the right track. Other metrics act as inputs feeding this one.
