North star metric
A North Star Metric (NSM) is the single metric that best captures the core value your product delivers to customers. It serves as a guiding light for the entire company, aligning teams around one measure of success that drives sustainable, long-term growth. Unlike vanity metrics, a North Star Metric connects customer value to business outcomes.
Why it matters
The North Star Metric creates focus and alignment:
Characteristics of a good north star metric

The NSM should reflect the value customers receive, not just business output.
Bad: Total revenue (business output)
Good: Weekly active subscribers (customer engagement)
Leads to revenue
While not revenue itself, the NSM should correlate strongly with sustainable revenue growth.
Reflects product strategy
The metric should align with your product vision and strategy.
Is measurable
You need to be able to track it reliably and frequently.
Is actionable
Teams should be able to influence it through their work.
Is understandable
Everyone in the company should understand what it means.

Common north star mistakes
Choosing revenue
Revenue is an output, not a measure of value. When revenue is the NSM, teams optimize for extraction over value creation.
Picking a lagging indicator
Metrics like annual renewals change too slowly to guide day-to-day decisions.
Multiple "north stars"
If you have more than one, you don't have a North Star. Pick one.
Ignoring input metrics
The NSM alone doesn't guide action. Teams need input metrics they can influence.
Gaming the metric
Without input metrics and qualitative feedback, teams may find ways to inflate the NSM without creating value.
