Market Segmentation
Kabir wants ReShelf to be "for all students". But a first-year engineering student buying five ₹1,200 textbooks and a final-year literature student who needs two paperback novels live in different worlds. A message that tries to speak to both speaks to neither.
The rule
Group customers by what they need, then pick the slice you'll win.
Segmentation splits a market into groups that need different things or behave differently. Common ways to slice:
- Demographic: age, income, year of study.
- Geographic: city, campus, hostel or day scholar.
- Behavioural: how people buy and use, such as buying everything in week one, or selling every term.
- Needs-based: what people are trying to achieve, such as the lowest price, the least effort, or the right edition.
For ReShelf, age is nearly useless, since almost every student is 18 to 22. Behaviour and needs split the market far better:
| Segment | Main need | Behaviour |
|---|---|---|
| First-year buyers | Right edition, low price | Buy a full list in two weeks |
| Final-year sellers | Quick cash, little effort | Sell a whole shelf once, then leave |
| Mid-course swappers | Trade last term's books for this term's | Buy and sell every semester |
| Literature and humanities students | Cheap novels and readers | Need few, low-priced books |
A good segment passes four checks: it has a distinct need, it is big enough to matter, you can reach it, and you can win it. The segment you start with, where you can win first and then grow, is often called your beachhead.
The shortcut
Run each candidate segment through need, size, reach, win. The one that passes all four is your beachhead.
First-year engineering buyers
Need: sharp, because their books are expensive and edition-sensitive. Size: about 2,000 a year on the pilot campus. Reach: all of them attend orientation week. Win: edition matching is exactly their pain. Passes all four.
The trap is "everyone is our customer". A product for everyone has no clear message, no channel, and no reason for anyone in particular to choose it.
Drills
Answer fast — trust the rule.
"Students who sell books every single semester" is which kind of segment?
Why is age a poor way to segment ReShelf's market?
A segment has a sharp need and is large, but ReShelf has no way to reach it yet. What should the team do?
What is a beachhead segment?
Remember
- Group customers by what they need, then pick the slice you'll win.
- Check every segment for need, size, reach and win; the winner is your beachhead.
- Trap: "everyone is our customer", which leaves you with no message at all.
