A good North Star Metric helps you focus on what actually moves growth.
Question 1 of 5
What are you building?
Example scenarios
Not sure if the tool applies to your situation? Here are common examples.
Early-stage SaaS with decent signups but low usage
North Star
Weekly activated users
Signups measure interest. Activation measures whether users got to the part where the product is useful. Fix that gap before optimizing anything else.
Content site with growing traffic but no repeat visitors
North Star
Weekly returning readers
Traffic from search is disposable. The readers who come back without being prompted are the ones building a real audience.
Marketplace with lots of listings but few transactions
North Star
Weekly successful transactions
Listings are supply. Transactions are proof that supply and demand are meeting. A marketplace without transactions is a directory.
Ecommerce store trying to grow beyond one-time purchases
North Star
Repeat purchase rate (monthly)
Acquiring new customers is expensive. The percentage who buy again tells you whether the product and experience are strong enough to sustain growth.
Developer tool with many installs but few active projects
North Star
Weekly activated projects
An install is a download. An activated project is a developer who set the tool up and used it for something real. That is the difference between interest and value.
SaaS product with growing revenue but rising churn
North Star
Monthly retained active users
Revenue can grow from new sales while the base erodes underneath. Retained active users shows whether the product is keeping the customers it already has.
What is a North Star Metric?
A North Star Metric is the single number that best captures whether your product is delivering value to users. It is not a vanity metric like total signups or pageviews. It is a measure of real, recurring value delivery. When this number is growing, your product is healthy. When it is flat or declining, something is off. The concept is simple but choosing the right one is where most founders struggle.
How to choose a North Star Metric
Start with the action that delivers the most value to your users. For a project management tool, that might be creating and completing tasks. For an analytics product, it might be receiving an insight. For a marketplace, it is completing a transaction. The right metric counts how many users complete that action within a meaningful time window, usually weekly. It should be specific enough to move when you improve the product and broad enough to reflect overall health.
Common North Star Metric mistakes
The most common mistake is choosing a metric that can grow while the product gets worse. Total signups is the classic example: it only goes up, even if nobody stays. Revenue is another: it can grow from one-time sales while churn erodes the base. A good North Star Metric should be sensitive to both improvements and problems. If you fix onboarding and your metric does not move, it is measuring the wrong thing. For a deeper look at this pattern, our guide on vanity metrics vs real metrics covers the distinction in detail.
Why most founders pick the wrong metric early
It is natural to focus on the metric that moves fastest. Early on, that is usually traffic or signups because those are the first numbers to appear. But the metric that moves fastest is rarely the one that matters most. The metric that matters is further down the funnel: activation, retention, or revenue. These numbers move slower but they are the ones that determine whether the product is building real value. The five metrics that actually matter guide covers which numbers to focus on and in what order.
