North Star metric
A North Star metric is a single quantitative measure that captures the value a product delivers to its users — chosen to align an entire organisation's decisions toward customer value rather than vanity metrics. Examples: Airbnb's nights booked, Spotify's time spent listening, Slack's messages sent in a team.
The framework, popularised by Sean Ellis around 2017, exists because most growth-stage companies have a hundred metrics and no shared answer to 'which one matters most'. The North Star is the answer. A good North Star has three properties: it measures customer value (not revenue or top-of-funnel); it's a leading indicator of long-term business outcomes; and it can be moved by product changes. Pitfalls: choosing a metric that's easy to game (e.g., 'minutes in app' incentivises addictive design); not breaking the North Star into 'input' metrics that teams can directly influence; treating the metric as fixed when it should evolve with the company's stage. Most healthy organisations revisit their North Star annually.
