One metric that captures the core value you deliver. If it goes up, the company wins.
TL;DR
Identify the single metric that best captures the value your product delivers to customers. Support it with 3-5 input metrics (levers) and monitor output metrics (business results). Align all teams around moving the NSM.
What Is North Star Metric?
The North Star Metric is the one number that best represents the value your product delivers to customers. If this metric goes up, the company is winning. Everything the team does should ultimately drive this one number.
The NSM sits at the intersection of customer value and business value. It's not a vanity metric (total users) or a pure business metric (revenue) — it captures the core value exchange. A good NSM reflects the 'aha moment' at scale: the point where customers experience the product's core value. The NSM is supported by input metrics (levers that drive it) and output metrics (business results it produces). It aligns the entire organization by providing a single, shared definition of success.

Origin & context
The term is generally credited to Sean Ellis, who coined 'growth hacking' in 2010, and it spread through growth teams at technology companies over the following decade.
Core Components
The North Star Metric
A single metric capturing the core value delivered to customers.
Example
Spotify: Time spent listening. Airbnb: Nights booked. Slack: Messages sent. Facebook: Daily active users.
Input Metrics
The 3-5 levers that drive the North Star Metric.
Example
For Spotify's 'time spent listening': new user activation rate, playlist creation rate, personalization accuracy, content catalog breadth.
Output Metrics
Business results that improve when the NSM improves.
Example
When Spotify's listening time increases: premium conversion goes up, churn goes down, ad revenue increases.
In a 2021 survey of more than 40 growth-stage companies, Lenny Rachitsky grouped their North Star Metrics into six categories: revenue, customer growth, consumption growth, engagement growth, growth efficiency, and user experience. The best NSMs combine customer value with a business outcome.
When to Use North Star Metric
Product-led growth strategy
Problem it solves: Aligns product, engineering, marketing, and sales around a single definition of value.
Real-world application
A team-messaging product that adopts 'messages sent per team' as its NSM can align the whole company: product optimizes for messaging ease, marketing targets teams rather than individuals, and customer success focuses on team activation.
Prioritization and focus
Problem it solves: Provides a clear filter for deciding what to build and what not to build.
Real-world application
When evaluating a new feature, the team asks: 'Will this increase our North Star Metric?' If no, it's deprioritized.
A good North Star Metric passes three tests: (1) It reflects customer value delivery, (2) It's a leading indicator of revenue, and (3) It's measurable and actionable. Revenue itself is usually not a good NSM — it's a lagging output of value delivery.
How to Apply North Star Metric: Step by Step
Before you start
- →Clear understanding of your product's core value
- →Analytics infrastructure to measure the metric
- →Team alignment on what value means for customers
Identify Core Value
Define the fundamental value your product delivers to customers.
Tips
- ✓Ask: 'What is the moment when customers experience our product's core value?'
Common mistakes
- ✗Choosing a metric that reflects company value (revenue) rather than customer value
Define the North Star Metric
Select one metric that best captures this value at scale.
Tips
- ✓Test: Does improving this metric correlate with improved retention and revenue?
Common mistakes
- ✗Choosing a vanity metric (signups) instead of a value metric (active usage)
Identify Input Metrics
Define 3-5 metrics that are the key levers driving the NSM.
Tips
- ✓Each input metric should be owned by a specific team
Common mistakes
- ✗Too many input metrics — keep it to 3-5
Align and Execute
Organize teams and priorities around moving the NSM and its input metrics.
Tips
- ✓Every team should know how their work connects to the NSM
Common mistakes
- ✗Defining the NSM but not changing team priorities or structure to support it
Value & Outcomes
Primary benefit
Aligns the entire organization around a single metric that captures both customer and business value.
Additional benefits
- ✓Simplifies prioritization decisions
- ✓Creates a shared language for success across teams

Best Practices
📋 Preparation
- •Understand your product's value proposition deeply
- •Analyze which metrics correlate with retention and revenue
🚀 Execution
- •Choose one metric — resist the urge to have multiple 'north stars'
- •Support it with 3-5 input metrics
🔄 Follow-Up
- •Review the NSM weekly with the leadership team
- •Reassess annually whether the NSM still captures core value
💎 Pro Tips
- •The best NSMs capture value delivery frequency: 'nights booked' (Airbnb), 'messages sent' (Slack), 'hours watched' (Netflix)
Don't confuse the NSM with the only metric that matters. The NSM is the guiding metric, but you still need input metrics (to know what levers to pull) and health metrics (to ensure you're not breaking other things).
Airbnb is widely cited as using 'nights booked' as its North Star Metric. It captures value on both sides of the marketplace at once: a guest found a place to stay and a host earned income, and it rises only when the core exchange actually happens.
Limitations & Pitfalls
Over-focus on one metric can create blind spots
Mitigation: Use health metrics alongside the NSM to guard against unintended consequences
The right NSM may change as the product and market evolve
Mitigation: Reassess annually and be willing to evolve the NSM
