The North Star Metric (NSM) is the one metric that best captures the core value your product delivers to customers. Everything your team does should ultimately move this number.
Why One Metric?
Having one primary metric forces clarity. It creates alignment across product, marketing, and engineering teams. And it gives everyone a simple way to evaluate whether their work is moving the company forward.
This doesn’t mean you ignore all other metrics — it means you have one metric that serves as the leading indicator of sustainable revenue growth.
Characteristics of a Good North Star Metric
A good NSM:
- Reflects customer value delivered, not just revenue
- Is measurable weekly or monthly (not annually)
- Is something your whole team can influence
- Has a causal relationship with long-term revenue
Examples by Business Type
| Company | North Star Metric |

| Duolingo | Daily Active Learners |
How to Find Yours
- Start with the value moment — what is the “aha moment” when a user first realises your product’s value?
- Find the metric that measures that moment at scale
- Check the correlation — does this metric correlate with long-term retention and revenue?
- Validate with your team — can everyone in the company describe how their work influences it?
Common Mistakes
Avoid revenue metrics (MRR, ARR) as your NSM — they’re lagging indicators. By the time they change, it’s too late to react. The NSM should be a leading indicator that predicts revenue weeks or months ahead.
