North Star Metric: Picking the One Number That Aligns

A north star metric aligns the whole company on one number. What makes a good one, common failure modes, and how the North Star changes with stage.

North Star Metric for Startups

A north star metric turns "do more good stuff" into "increase this specific number." Chosen well, it aligns product, sales, and marketing. Chosen badly, it points the team at the wrong outcome for years.

What makes a good north star

Measures value delivered, not activity. Directly correlates with revenue. Simple enough for every employee to understand. Movable by the team's actual work. Not a vanity metric.

Examples

Airbnb: nights booked. Slack: paid weekly active users. Facebook: monthly active users. Spotify: minutes listened. Each captures the moment of value delivery, not signups or downloads.

Failure modes

Choosing a lagging revenue metric (drives short-term behavior). Choosing an activity metric (users become the wrong kind of active). Multiple north stars (which is code for none). Changing it every quarter.

By stage

Pre-PMF: activation rate or engaged users. Growth stage: revenue metric with a value modifier (paid WAU, engaged accounts). Scale: revenue itself, decomposed into acquisition + retention + expansion.
