## Definition

A north star metric is the single measure that best captures the core value customers get from a product, used to align the whole team on one number that predicts sustainable growth.

## What it means in practice

A north star metric exists to prevent teams optimising conflicting things. When marketing chases signups, product chases engagement and sales chases contracts, effort can increase while the business does not improve. A shared metric that captures delivered value keeps those efforts pointed the same way.

The essential property is that it measures value received by the customer, not activity by the company. Signups measure interest, and revenue is a lagging consequence — neither tells you today whether people are getting what they came for. Good north stars measure the moment value is actually delivered: nights booked, messages sent, reports generated, invoices paid.

A well-chosen metric is difficult to game in harmful ways. If a team can improve the number through dark patterns without customers benefiting, the metric is wrong. The test is whether the number rising necessarily means customers are better off — if not, it will eventually be optimised against the business.

## Worked example

Choosing a north star for an invoicing product.

- Candidate: signups — measures interest, not value; can rise while the product fails.
- Candidate: MRR — a lagging outcome; tells you nothing about today's delivered value.
- Chosen: invoices successfully paid through the platform per week.
- This can only increase if customers are genuinely getting paid — the actual outcome they hired the product for.

**Takeaway:** The chosen metric cannot rise without customers succeeding, which makes it both a growth predictor and safe to optimise aggressively.

## Common mistakes

- Choosing revenue, which lags and reveals nothing about whether value is being delivered now.
- Choosing a vanity metric such as signups or pageviews that can grow while the business declines.
- Picking a metric that can be improved through dark patterns without benefiting customers.
- Tracking several 'north stars', which defeats the purpose of having one shared number.

- [Product-Market Fit](https://skiporship.com/glossary/product-market-fit) — Product-market fit is the point where a product satisfies a real, urgent demand well enough that customers adopt it, keep using it, and tell others — so growth starts pulling rather than being pushed.
- [Cohort Analysis](https://skiporship.com/glossary/cohort-analysis) — Cohort analysis groups customers by when they joined and tracks each group's behaviour over time, revealing retention and revenue patterns that aggregate metrics hide.

## FAQ

**What makes a good north star metric?**

It measures value actually delivered to customers, predicts long-term growth, can be influenced by the team's work, and cannot be improved in ways that harm customers.

**Should revenue be the north star metric?**

Usually not. Revenue is a lagging indicator that confirms value was delivered in the past. A good north star measures the delivery of value as it happens, so it can guide decisions before revenue moves.
