The Customer Segment Slicing Method
Narrow your customer segment until you know exactly where to find them
The Customer Segment Slicing Method is a process for narrowing a broad, vague customer group into a specific, actionable target segment that you can find, reach, and serve. The key insight is that when your customer segment is too broad, you get meaningless, contradictory feedback because different types of people within that group have fundamentally different needs.
The technique involves progressively slicing a broad segment into thinner, more specific groups until you reach a who-where pair: a specific type of person and a specific place where you can find them. For example, 'students' is too broad. 'Students who are scared of public speaking' is better. 'Non-native-speaking PhD students who have an upcoming conference presentation' is specific enough that you know exactly where to find them and what they need.
Before you can serve everyone, you have to serve someone. The slicing continues until you can answer three questions: who are they specifically, where can you find them, and are they reachable, profitable, and personally rewarding to work with? You can always broaden your segment later once you have proven the model with a narrow initial group.
- Before we can serve everyone, we have to serve someone
- Good customer segments are a who-where pair
- If you do not know where to find your customers, keep slicing your segment smaller
- Talking to everyone means most conversations are with the wrong people
- The segment should be reachable, profitable, and personally rewarding
- Three criteria for a good segment: you know who they are, you know where they are, and they share similar motivations
- Define your starting segmentWrite down your current target customer description. Be honest about how vague it is. If it is something like 'small business owners' or 'students,' it is almost certainly too broad to be useful.
- Add demographic and behavioral specificsLayer on specific demographic characteristics and behavioral indicators. Instead of 'people scared of public speaking,' consider 'non-native-speaking professionals who have to present regularly and are actively trying to improve.' Existing behavior like attending workshops or reading books is a strong signal.
- Identify the whereFor each narrowed segment, ask where you can physically or digitally find these people. If you cannot answer this question, the segment is still too broad. Keep slicing until you can name specific locations, communities, events, or online platforms.
- Evaluate and chooseAssess each candidate segment against three criteria: are they reachable (can you actually get in front of them), are they profitable (can they pay enough to sustain your business), and are they personally rewarding (will you enjoy working with them). Choose the segment that scores best across all three.
A founder had a healthy food condiment with countless potential uses: breakfast, protein shakes, kids' food, restaurant tables. She was running in circles because bodybuilders, restaurants, and moms each wanted different things. By slicing the segment to focus specifically on moms with young kids who currently shop at small independent health food stores, she identified both her ideal customer and a distribution partner in the same place.
Fitzpatrick observed that many founders try to talk to everyone and end up learning nothing because different customer types within a broad segment have conflicting needs. He worked with a founder selling a healthy food condiment who was paralyzed because bodybuilders, restaurants, and moms each wanted different things. By slicing the segment to focus on moms shopping at small independent health food stores, the founder was able to make progress and test assumptions with a concrete commitment.
