North Star Metric
The North Star Metric is the single metric that best captures the core value your product delivers to customers. It aligns every team around a shared outcome and drives sustainable growth by focusing on customer value, not vanity metrics.
§ 1 Definition
The North Star Metric (NSM), a concept popularized by Sean Ellis and growth teams at companies like Facebook, Airbnb, and Spotify, is the single metric that most directly measures the value a product delivers to its customers. It is the metric that, if improved, will drive long-term sustainable growth across the entire customer base. Unlike revenue (which can be short-term optimized by cutting retention investment) or user count (which can grow while engagement declines), the North Star Metric focuses on the core value experience. For Facebook, it is Daily Active Users (the core experience is connecting daily). For Airbnb, it is Nights Booked. For Spotify, it is Time Spent Listening. The NSM aligns product, marketing, engineering, and leadership around a single outcome that truly matters.
§ 2 What Makes a Good North Star Metric
A good NSM has five characteristics. It measures customer value, not company value (revenue is a lagging indicator of value delivered, not the value itself). It aligns with the product's core experience (if users stop doing this, they are not getting value). It is leading, not lagging (improving it predicts future revenue and retention). It is understandable by every team member from engineering to support. It is actionable: teams can directly influence it through their work. A NSM that fails any of these tests will not be effective in aligning the organization.
§ 3 North Star Metric vs. Revenue
Revenue is not a North Star Metric. Revenue is an outcome of delivering value. Optimizing for revenue directly can lead to short-term decisions that damage long-term growth (cutting retention spend, raising prices without adding value, aggressive upsells that annoy customers). The NSM focuses on delivering customer value, and revenue follows. This is the core insight behind product-led growth: measure and maximize the value you deliver to customers, and the business results will take care of themselves.
§ 4 Examples of North Star Metrics
Facebook: Daily Active Users. Airbnb: Nights Booked. Spotify: Time Spent Listening. Uber: Rides Completed. Slack: Messages Sent. Dropbox: Files Synced. Quora: Questions Answered. Peloton: Workouts Per Subscriber. Notice a pattern: each measures the core value exchange, not an intermediate metric like signups or page views. The NSM captures the moment when a user receives value from the product.
§ 5 Implementing a North Star Metric
Define your NSM by identifying the core value users get from your product. Interview power users who have gotten deep value: what are they doing? What would they miss most if it disappeared? Quantify that value as a single metric. Instrument it in your product analytics. Communicate it across the company as the shared goal. Build team-level OKRs and KRIs that ladder up to the NSM. Review the NSM quarterly to ensure it still reflects value delivery as the product evolves. If your product changes significantly, your NSM may need to change too.
§ 6 Note
§ 7 Common questions
- Q. Can a company have more than one North Star Metric?
- A. No. That defeats the purpose. The NSM is designed to create singular focus. You can have supporting input metrics for different teams, but the NSM should be one number that everyone in the company knows and tracks.
- Q. What if our North Star Metric starts declining?
- A. Investigate immediately. A declining NSM means you are delivering less customer value. This is a more important signal than a revenue dip, because it precedes the revenue dip. The NSM is an early warning system.
- Q. Should the North Star Metric change over time?
- A. It should not change frequently. A NSM should be stable for years. But if the product fundamentally changes (new market, new core use case), the NSM may need to evolve. Review annually, but only change when the evidence is clear.

## Note
The North Star Metric is a north star, not the only metric. You still need supporting metrics for each team and each function. But the NSM provides a single compass direction that prevents teams from optimizing for conflicting goals.
