Customer segmentation is your secret weapon—why specificity beats trying to please everyone

Hard - Requires significant effort Recommended

Many ambitious projects fail because they try to serve everyone right out of the gate. It’s tempting to believe your idea is universal, that 'everyone' with a small business or studying for exams could benefit. But the reality is, these broad segments are filled with wildly different needs, motivations, and constraints that can quickly overwhelm any team. Feedback gets muddled, priorities clash, and progress stalls.

Teams that thrive start by narrowing their focus. When one product developer reimagined her target from 'health-conscious individuals' to 'moms with young kids shopping at health food stores,' suddenly the process became actionable. She knew where to find her audience, what language would resonate, and where to test early versions. The feedback she got was clearer, more consistent, and quickly pointed the way to improvements that mattered.

This practice is known as 'customer segmentation,' a concept rooted in marketing science and validated time and again by growing companies. Instead of being pulled in every direction by conflicting feedback, you become an expert in a single group’s needs. Over time, as you build trust and get things right for this segment, you have a launch pad to expand and tackle new markets. The discipline of specificity—of knowing exactly who and where you serve—turns overwhelming complexity into confident, focused action.

When you feel spread thin trying to please everyone, pause and name exactly who you hope to help—write down an actual description and list where you’d go to find these people. Keep splitting and focusing until you reach a segment that is easy to reach and observe. Then, start your learning and product experiments there, adjusting as you uncover what truly works. Once you’ve built something they value, you’ll be ready to expand step-by-step, making each new segment as specific as the last.

What You'll Achieve

Internally, this will help you feel less overwhelmed and more in control of your project direction. Externally, you'll get clear, actionable feedback, faster learning cycles, and a better chance of delivering real value, maximizing your odds of early traction.

Focus On A Specific Who-Where Pair

1

Identify exactly who, and where, your customer is.

Rather than serving everyone, narrowly define the demographic and context that most needs your solution—who and where can you actually find them?

2

Slice broader categories into smaller, action-ready segments.

Take a generic segment (like 'students' or 'athletes') and repeatedly divide until you end up with a group you can locate and observe in the real world.

3

Validate with focused conversations in that niche.

Conduct a handful of conversations only within this segment, tuning your questions and product to their needs before considering expansion.

Reflection Questions

  • How narrow is my current customer segment, really?
  • What conflicting signals have I received from trying to serve multiple groups?
  • Where can I physically or virtually meet my specific audience?

Personalization Tips

  • Instead of targeting all students, start with students training for math competitions at your local high school.
  • For a diet product, focus on busy parents shopping at a specific grocery store chain.
  • If launching an office tool, begin with small businesses in your city’s main co-working space.
