What is a North Star Metric? (and how to actually use one)

Most companies have dashboards full of metrics. Revenue, traffic, signups, churn, NPS scores — all tracked, all reported in weekly meetings, none of them clearly in charge.

A North Star metric tries to fix this. It is one number that captures the core value your business delivers to customers. When it goes up, good things follow. When it stalls, something is broken.

The concept sounds simple. In practice, most teams either pick the wrong metric or pick the right one and then quietly ignore it. This guide covers both problems.

North Star metric definition

A North Star metric (sometimes called an NSM) is the single most important metric a company tracks. It represents the core value you deliver to customers — not just the commercial outcomes you extract from them.

The term was popularised by Sean Ellis in the early 2010s in the growth community. 

The idea: if you could only optimise one number, what would it be? Not revenue. Not page views. Something that genuinely reflects whether customers are getting value from your product.

A good North Star metric has three properties:

• It reflects customer value, not just company extraction
• It predicts long-term business health, not just short-term performance
• It is something every team can connect their work back to

That last point matters more than most people acknowledge. A North Star metric only works if it creates alignment. If the engineering team, the marketing team, and the sales team all understand it and can trace their work back to it, it becomes a genuine organising principle. If only the product team tracks it, it is just another dashboard number.

North Star metric vs vanity metrics

Vanity metrics look impressive in a board presentation. North Star metrics tell you whether you are actually building something people value.

The most common vanity metrics in the wild:

• Total registered users (not the same as active users)
• App downloads (not the same as retained users)
• Website traffic (not the same as qualified traffic)
• Social media followers (almost never correlated with revenue)

The test: would this number go up even if your product was getting worse? If yes, it is probably a vanity metric. Downloads can increase while engagement collapses. Website traffic can spike because of a viral post that has nothing to do with your core audience.

A North Star metric should fail this test. If customers are getting less value from your product, your North Star should reflect it. If it does not, you have chosen the wrong metric.

North Star metric vs KPIs: what is the difference?

North Star metrics and KPIs are related, but they are not the same thing.

A KPI (key performance indicator) is a metric used to measure progress toward a specific goal. A company can have dozens of KPIs across different teams and functions. For a deeper look at how these two frameworks intersect, see OKRs vs KPIs. KPIs are operational.

A North Star metric is singular and strategic. It is the one metric that represents the overall direction. In practice, your North Star metric often becomes the most important KPI — but not all KPIs are North Star candidates.

Here is a way to think about the hierarchy: your North Star metric sits at the top. Your team-level KPIs describe the specific levers that move it. Your OKRs translate those levers into time-bound goals with clear ownership and regular check-ins.

This hierarchy is what most articles on North Star metrics leave out. Choosing a metric is the easy part. Building the system that connects it to day-to-day work is where most companies struggle.

How to choose your North Star metric

Four questions that help narrow it down:

1. What action indicates a customer is genuinely getting value?

Not signing up. Not installing. The moment they actually get what they came for. For Spotify, that is someone listening to music. For Airbnb, it is a completed booking. For Slack, it is messages sent within an active team. Find the action that reflects real value delivery, not just the start of a customer journey.

2. Does this metric lead revenue, or just track it?

Revenue is a lagging indicator. Your North Star metric should predict it, not mirror it.

If you track 'messages sent per team', you expect that engaged teams will convert to paid plans and renew. The metric should come before the commercial outcome, not alongside it.

3. Can every team contribute to it?

If the metric is only moveable by one team, it is not North Star material. A genuine North Star creates cross-functional alignment. Marketing, product, customer success, and engineering should all be able to draw a line from their work to the metric. If they cannot, it is a product metric, not a company metric.

4. Would a bad actor be able to game it?

If the metric can be inflated without delivering more customer value, it will eventually be gamed. 'Sessions' can be inflated with dark patterns. 'Time in app' can increase because the product is confusing. Choose metrics that are hard to fake.

North Star metric examples by business type

Different business models have different definitions of customer value. Here are common examples, along with why they work:

Notice that none of these examples are 'revenue' or 'new signups.' Those matter. But they are outcomes of the North Star metric, not the metric itself. Revenue follows when customers get consistent value. Build the metric around value, and revenue follows.

Connecting your North Star metric to your OKRs

Picking a North Star metric is only the first step. 

The harder question is: how do you connect it to the work your teams are actually doing every quarter?

This is where OKRs come in.

Your North Star metric describes where you want to go. Your OKRs describe the specific progress you are committing to make this quarter. Each key result is a measurable contribution to moving the North Star.

For example, if your North Star metric is 'weekly active teams', your Q2 OKRs might include:

• Increase activation rate for new signups from 40% to 60%
• Reduce time-to-first-value from 5 days to 2 days
• Launch onboarding improvements that lift 30-day retention by 15%

Each of these is a lever that moves the North Star metric. Together, they form a coherent strategy — not just a list of tasks.

Tools like Tability are built specifically for this connection. You can set your North Star metric as a top-level outcome, then layer OKRs and initiatives underneath it. Teams run weekly check-ins on their key results, and you can see in real time how progress on individual OKRs is tracking toward the North Star. It replaces the gap between 'we have a strategy' and 'we know whether it is working.'

Make your North Star metric mean something

A North Star metric on a slide deck is just a number. A North Star metric connected to team goals, tracked every week, and reviewed every quarter becomes something different. It becomes a shared definition of what success looks like for everyone in the organisation.

Most companies skip the connection step. They pick the metric, announce it, and then continue tracking the same KPIs they always did. Nothing changes because nothing changed about how work is organised or reviewed.

The fix is not complicated. Define your North Star metric clearly, then build your OKRs around moving it. Review both together, regularly. When a team's work is not traceable to the North Star, ask why. That conversation alone surfaces more strategic clarity than most quarterly planning sessions.
