North Star Metric
North Star Metric
What is a North Star metric?
- One metric that stands in for customer value
- Leading power and resistance to manipulation are the criteria
- Pair it with sub-metrics and guardrails
The first thing that changes once you set a North Star is the language of meetings. Before that, marketing brought lead counts, sales brought contract value, and CS brought response times. Everyone made a valid point and nothing got decided. Once one number stands, every agenda item gets the question “does this move that number?”, and priority fights turn from a battle of tastes into a calculation. When deciding where to put more budget and headcount, the rationale converges in one place. It is less about adding new metrics than about ranking the ones you already have scattered around.
When choosing candidates, it helps to sort them into three types: usage-based (total weekly usage hours), user-based (weekly active client companies), and outcome-based (number of results customers actually achieve). Subscription businesses usually fit the usage type, while brokerage or solution businesses usually fit the outcome type. Then check for leading power: look at the past 4–6 quarters of data to see whether this number moved about a quarter ahead of revenue or renewal rate. If the correlation isn’t clear, it is likely a number chosen because it was easy to count. A North Star also differs from KPIs. KPIs are multiple evaluation numbers set per department, whereas the North Star is a single company-wide number used to set direction, not to evaluate.
The most common misstep in practice is tying this number directly to executive evaluations and bonuses. The moment that happens, business units look for the cheapest way to raise the number. At a training company, if 'number of on-the-job application cases' is tied to evaluations, you get a flood of one-line, pro forma reviews. The North Star is a compass for direction, not a bonus calculator. Skipping guardrails is also common. Without minimum thresholds such as churn rate or cost ratio alongside it, the metric keeps rising while profitability quietly erodes, and this surfaces about six months later. Many organizations also keep using a metric from three years ago after their business model has changed, so at least once a year, check again whether the number still reflects customer value.

It is widely cited in growth-hacking discussions, including by Sean Ellis.
Consider a hypothetical case. Company A is a B2B SaaS firm with 90 employees and annual revenue of KRW 14 billion (≈ US$10,474,300). For two years, sign-ups kept growing while real results lagged. Marketing brought sign-up counts, sales brought contract value, and product brought the number of features shipped, so each quarterly strategy meeting spun its wheels for three hours. In effect, one company had three definitions of success.
- The head of strategic planning went back through the last four quarters. New sign-ups were up 32%, but the renewal rate had slipped from 74% to 68%. In the meeting someone said, "The number we count has come apart from the value customers feel."
- The product lead compared three candidates, weekly logins, monthly reports generated per account, and breadth of feature use, against the renewal rate. Only the number of reports generated tracked clearly, with a correlation coefficient of 0.71.
- The CFO pushed back: "If we only watch that number, we’ll start handing out free accounts." So they added guardrails alongside it: a support cost ratio of 22% or less per account, and inquiry response within 4 hours.
- Sales took “share of accounts that generated 3+ reports” and marketing took “days to first report” as sub-metrics, and the first screen of the Monday weekly meeting was changed to this single number.
- Two quarters later, monthly reports generated per account rose from 4.2 to 7.1, and the renewal rate recovered from 68% to 79%. Quarterly strategy meetings also shrank from 3 hours to 1 hour 30 minutes.
