⭐Learn the North Star Metric: One Number That Captures Value
Pressure-test real company north stars against three hard criteria, then define and defend one for your own product. Leave with a metric your team can rally around — not another vanity dashboard.
Phase 1Three Criteria That Separate Real North Stars From Vanity
Meet the three criteria a real north star must pass
Most teams pick a vanity metric and call it a north star
6 minA North Star Metric isn't your biggest number — it's the one that goes up only when users get more value.
It must capture value delivered, not activity performed
6 minValue is what the user walked away with. Activity is what the product recorded. Real north stars track the first, not the second.
It must be a leading indicator, not a trailing one
7 minRevenue tells you what already happened. A north star tells you what's about to.
It must be usable by every team, not just growth
6 minA north star that only product and growth understand isn't a north star — it's a dashboard. Engineering, support, and sales all need a line from their work to the number.
Phase 2Dissecting Famous North Star Metrics
Dissect five famous metrics and explain why they work
Why Airbnb chose 'nights booked' over signups or revenue
7 minNights booked passes all three criteria — value, leading, usable — which is why it survived a decade of product shifts.
Slack's 2,000-message threshold, and why the number matters
7 minSlack didn't just pick 'messages sent' — they picked a team-level threshold that predicts retention with startling accuracy.
Why 'time listening' beats 'songs played' for Spotify
6 minSongs played rewards skipping. Time listening only rewards songs people actually wanted to hear.
Two more case studies, and one with a tradeoff most miss
7 minAmazon's 'purchases per customer' and Netflix's 'hours watched' pass the criteria — but Netflix's choice reveals a tradeoff most teams never surface.
Score five metrics against the three criteria — fast
8 minRunning the criteria on a batch of real candidates builds the muscle. The test stops feeling like a quiz and starts feeling like taste.
Phase 3How the NSM Connects to AARRR, OKRs, and Unit Economics
Wire the NSM to AARRR, OKRs, and unit economics
Your NSM lives inside one stage of the AARRR funnel
7 minEvery North Star Metric sits at a specific point in the Acquisition → Revenue funnel. Knowing which stage tells your team where to focus and where to stop worrying.
Your NSM is the top of the OKR tree
7 minOKRs without a North Star produce motion without direction. The NSM is the Objective every Key Result should trace back to.
A growing NSM with bad unit economics is a subsidy, not a business
8 minThe North Star tells you what you're trying to grow. Unit economics tell you whether growing it actually makes money.
NSM, AARRR, OKRs, unit economics — one coherent stack
8 minWhen all four layers point the same direction, strategy feels obvious. When they don't, you have a company arguing with itself.
Phase 4Define and Stress-Test Your Own North Star
Define and stress-test a north star for your product
Define your NSM and defend it against the three criteria
8 minEvery concept in this path folds into one deliverable: a North Star Metric for your product, written clearly and stress-tested enough that a skeptical colleague can't knock it over.
