The metric that lies and the one that tells the truth: I chose your North Star Metric
There is a moment in the life of almost every startup or growing company where the team has access to more data than ever—and less clarity than ever. Dashboards filled with numbers, meetings that start with slides of metrics, and a question that no one asks out loud: of all this, which number really matters?
72%
Teams report having too many metrics and very little clarity about which ones matter(Gartner, 2024)

of high-growth companies, they have a single metric that guides their product and commercial decisions (OpenViewPartners)
The level meter does not measure quality
In professional audio, the level meter shows the volume of the signal. A high level means that there is a lot of sound. It doesn’t mean that that sound is good, that the mix is well balanced, or that what is being recorded is worth listening to.
Vanity metrics work exactly the same way. They show activity, volume, and presence. But they don't tell you whether that activity is generating real growth.
According to Gartner, 72% of teams report having too many metrics and very little clarity about which ones matter for business decisions. The result is long meetings discussing numbers that don't change any decision.
A high-level meter does not mean that the signal is good. It could be noise at maximum volume. The same goes for vanity metrics: too many numbers, little information.
Vanity metrics vs. real traction metrics
The distinction lies not in the name of the metric but in what it reveals about the real health of the business. A real traction metric is one that changes when the business is doing better or worse, that the team can influence with concrete decisions, and that predicts the future behavior of the customer.
| Metric | It seems important because... | The problem is that... | The real metric is... |
|---|---|---|---|
| Followers on social media | It shows that the brand is growing | It does not indicate whether someone is going to buy or if those who follow will fit the ICP | Conversion rate from follower to qualified lead |
| Site visits | It shows that there is traffic and reach | Without segmentation by source and intent, the number says nothing actionable | ICP visits identified with time on the page longer than 2 minutes |
| Generated leads | Shows marketing activity | A lead that does not match the ICP consumes team time without being converted. | MQLs that meet the criteria of the real ICP per channel and per campaign |
| Email opening rate | It shows that the list is active | Opening is not buying. A high rate with low conversion is a message problem | Click-through rate towards high-intent action by ICP segment |
| NPS general | Demonstrates customer satisfaction | A high NPS with high churn is a contradiction that hides a problem | NPS segmented by customer type and correlated with renewal |
What is the North Star Metric and why does everything change
The concept of the North Star Metric was popularized by Sean Ellis and the Amplitude team Because it is the only metric that best captures the value that the company delivers to its customers. Not the value for investors or the team — the value for the customer. The logic is simple: if the company is delivering real value to its customers, the financial growth will follow.
The North Star Metric is not the largest or the easiest metric to climb. It is the one that has the most direct correlation with retention and long-term growth. And it is the one that, when it falls, indicates that something fundamental is failing before the revenue reflects it.
A high-level meter does not mean that the signal is good. It could be noise at maximum volume. The same goes for vanity metrics: too many numbers, little information.
Examples of North Star Metrics by business type
The North Star Metric is specific to each business and each stage. These are examples of how it looks in different types of companies:
SaaS B2B
Weekly active users who complete the core flow of the product
Not active subscribers — users who actually use what the product solves. The difference between the two predicts churn before it happens.
Marketplace
Transactions completed between ICP buyers and sellers
No visits, no registrations, no published listings. The value of a marketplace lies in the transactions it connects, not in the volume of participants.
Consultant or agency
Customers who renewed or extended the scope of the service
No closed projects or total revenue. In services, the customer who renews is the most direct indicator that the value delivered justifies the investment.
E-commerce
Customers who bought more than once in the last 90 days
No total revenue or transactions. The second purchase is the indicator that the first experience generated trust — and it is 5 times cheaper to achieve the first one.
How to find your business's North Star Metric
According to Amplitude Research, companies with a well-defined North Star Metric have four times more team alignment and make decisions faster. The process to find it, however, requires honesty about what really matters:
1 - Define what value is for your customer
It’s not about selling to them; it’s about transforming them into your business or life when what you sell works well. That transformation is the center.
2 - Find the metric that best measures that transformation
Not the one that is easier to upload — the one that most directly indicates that the customer is getting the value you promised.
3 - Validate that it predicts retention and growth
Customers with the highest value in that metric are the ones with the lowest churn and the most referrals? If the answer is yes, you have found the right candidate.
4 - Communicate it to the entire team
The North Star Metric only works as a north star if everyone knows about it, understands why it matters, and can connect their daily work to moving it.
The diagnosis of your metrics:
— How many metrics does your team review weekly? If they are more than 5, probably none of them is the North Star.
— When a key metric falls, the team immediately knows what action to take?
— Is there a metric whose increase correlates directly with lower churn and higher LTV?
— Can everyone on the team say without hesitation which is the most important metric of the business?
If the answers are no, the metrics system is measuring activity rather than traction. And the difference between the two is exactly what separates decisions that grow the business from those that make the team feel good.
