Why this matters
The same problem lives in many places, but you can only serve one well at first. Listing three candidate segments, and choosing one deliberately, replaces "we'll sell to whoever shows up" with a beachhead you can actually reach, win, and expand from.
What "done" looks like
- Three segments written down, each specific enough to find on a list
- Each scored on: pain intensity, ability to pay, reachability, and speed to decide
- One chosen as the beachhead, with a sentence on why
- The other two parked, not deleted, they are your expansion map
How to do it
- Generate candidates from your problem statement: who hits this trigger most often? Vary by role, company size, industry, or situation.
- Make each segment findable. "SMBs" is not a segment; "independent dental clinics with 2 to 10 staff" is, you could build that list.
- Score honestly across the four axes. A segment with moderate pain that you can reach tomorrow beats one with severe pain hidden behind procurement.
- Pick ONE beachhead. The test: can you name 20 real prospects in it this week?
- Write the choice down and revisit after your first ten interviews, segments often sharpen or swap once you talk to people.
Common mistakes
- Segments so broad they cannot be listed, contacted, or disproven
- Choosing the biggest market instead of the most winnable one
- Serving two segments "because both showed interest" and building for neither
Real-world examples
- The widely taught approach is to start narrow: pick one or a few tightly defined segments who feel the problem most acutely, rather than aiming at "everyone" and reaching no one. A specific segment is easier to find, talk to, and sell.
- A common experience is that the segment you write down first and the segment that actually pays turn out to be different people, the list is a starting hypothesis, not a verdict, and it usually sharpens once you interview real prospects.
- Segments are only useful if they're distinct in how they buy or what they need; if three "segments" would all get the same pitch, they're really one, and you should split on a real difference instead.
From a founder's point of view
Naming three segments forces a useful discomfort, you have to admit you can't serve everyone at once. The point isn't to permanently exclude anyone; it's to pick who you'll obsess over first so your messaging, pricing, and product decisions have an actual audience in mind. Vague targeting feels safe but usually produces a product that's slightly wrong for everybody.
Rule of thumb
A real segment is one where members know each other, same forums, same events, same job title. Word of mouth only works inside such a group.
