Lesson

Who is your customer?

By the end you will be able to describe your customer in a single sentence.

12 min read5 min activity

Your customer is not “everyone”.

Focusing does not mean refusing anyone. It means knowing who you speak to first.

What you'll learn

By the end of this lesson you will be able to:

Describe who your business serves.
Explain the problem you solve for them.
Identify where you can reach that customer.

The idea

Why “everyone” is too much

“Everyone” is too broad

When you speak to everyone, your message has to be so general that it says nothing special to anyone. It is like talking in a crowded plaza: many people hear you, but nobody feels you are talking to them.

Focus makes your message clear

When you know who needs you most, you can talk about their problem in their own words. That person reads your message and thinks: “this is for me.”

Clarity helps you decide

Knowing your customer puts three things in order: your pricing (what they value and why they would pay for it), your advertising (where to show up and what to say), and your decisions (what to offer first and what to say no to for now).

You are not closing the door. You are deciding who you greet first.

Picture it

From “everyone” to your message

01
Everyone
Anyone could buy from you. That is why it is not a useful description.
02
Who needs it most
The group with the problem you solve best.

Illustrative example

Rosa's Bakery

Rosa is in her first month. She posted “I make everything, for everyone” and received impossible requests: one hundred cupcakes for tomorrow, a discounted wedding cake, people who ask the price and disappear. She reviewed her first real sales: almost all were families in her neighborhood ordering custom birthday cakes by WhatsApp. She changed her message to speak to them.

Rosa still serves whoever shows up. But now she knows who she speaks to first, and her message finally says something to someone.

Compare

Weak versus strong

Weak description · Does not help

“My customer is anyone who wants to buy.”

It does not tell you what to write, where to advertise, or what to offer first.

Strong description · Helps

“Families in my neighborhood who need custom birthday cakes with 2–3 days' notice and prefer to order by WhatsApp.”

Who: “Families in my neighborhood”A real group you can picture and find.
Problem: “need custom birthday cakes”What that person wants solved.
Where: “prefer to order by WhatsApp”

Your turn

Build your customer sentence

Answer in your own words. The sentence is built only from what you type: if you leave something blank, it stays blank. Your first version is an assumption; you will check it later.

Your sentence

0 of 5 answers

I help [who] with [problem] in [where] by offering [what you sell]. They choose me because [why you].

It is built only from what you type.

Your answers are saved only on this device. Nothing is sent to Leonix or to any AI.

What do I do with this now?

This sentence is your first customer draft: a working hypothesis, not finished advertising copy.

It puts what you currently believe about who you serve in order.
It helps you think about your message, where to reach those customers, and what you still need to find out.
It still has to be tested against real people and what actually happens in your business.

Your answers are now ready as context for the AI conversations just below.

version 2

I have decided to start a small business in [city] and I am getting ready to serve my first customers. This is what I currently understand about my customer. These are my best assumptions, not proven facts: What I sell: [what you sell] Who I think needs it most: [who needs it most] The problem I think I solve: [what problem you solve] Where I think I can reach them: [where they are] Why I think they may choose me: [why they would choose you] Act as a patient business mentor and use plain language. Guide with stewardship, service, integrity, excellence, responsibility, and wisdom. Profit is necessary: it should help the business survive, pay people, reinvest, serve better, and leave something sustainable. Do not advise domination, manipulation, inflated promises, or growth for its own sake. Do not quote religion or preach. 1. First ask me whatever you need to know about my first possible customers and how I plan to reach them. 2. Help me decide which group to speak to first and what customer information I am still missing. 3. Turn that into a short list of actions and of evidence I should gather before I launch, and tell me what to check by talking with real people. Do not invent dates, prices, requirements, or facts about my customers or my market. If you assume something, label it as an assumption and tell me how I could check it.

There are still blanks in brackets. You can fill them in here or directly in your assistant.

Before you paste: remove your customers' personal details. Afterwards: check what matters with real people.

Why it works

It opens with your goal and your stage: the AI knows what you need it for.
You give it context: your five answers, stated as hypotheses and not as facts.
You give it a clear role: a patient mentor using plain language.
You ask it to ask for what is missing instead of making it up.
It separates assumptions from facts and ends with what to check with real people.

version 1

I have decided to start a small business in [city] and I am getting ready to serve my first customers. This is my starting point. These are my own assumptions: What I sell: [what you sell] Who I think needs it most: [who needs it most] The problem I think I solve: [what problem you solve] Where I think I can reach them: [where they are] Why I think they may choose me: [why they would choose you] Do not give me answers yet. Interview me: ask me about 5 questions, one at a time, and wait for my answer before asking the next one. Ask me about my first possible customers, about how I plan to reach them, and about the evidence I have so far. When I finish answering, summarize in my own words what you learned about my customer, point out what is still an assumption, and tell me what I should ask real people. Do not invent anything I have not told you.

There are still blanks in brackets. You can fill them in here or directly in your assistant.

Before you paste: remove your customers' personal details. Afterwards: check what matters with real people.

Why it works

It flips the order: questions first, answers later.
One question at a time makes you think, not just read.
It asks for a summary in your own words and for what is still an assumption.

Challenge my assumptionsWhat this helps with: To find the weak spots in your customer thinking before they cost you money.

version 1

I have decided to start a small business in [city] and I am getting ready to serve my first customers. This is what I believe about my customer: What I sell: [what you sell] Who I think needs it most: [who needs it most] The problem I think I solve: [what problem you solve] Where I think I can reach them: [where they are] Why I think they may choose me: [why they would choose you] I do not want you to agree with me: I want you to test my thinking, respectfully. 1. Separate what I seem to actually know from what I am only assuming. If it is not clear, ask me. 2. Point out the 2 or 3 weakest or riskiest assumptions and explain why. 3. For each one, tell me what I should check before I launch and the simplest way to do it. Do not present market facts as if they were certain: if you did not get them from me, say so.

There are still blanks in brackets. You can fill them in here or directly in your assistant.

Before you paste: remove your customers' personal details. Afterwards: check what matters with real people.

Why it works

It takes away the AI's habit of agreeing with you.
Separating what you know from what you assume shows you where the risk is.
It ends with actions to check, not with opinions.

Make it yours

Your five answers from “Your turn” are already included; change one there and it changes here.
Add your city or area: the customer in one neighborhood is not the customer in another.
Check your stage: an idea, getting started, or already operating. It changes the conversation.
Add what you already know about the people who buy or ask, without personal details.

Keep asking

What assumptions did you make? List them and tell me how to check each one.
Give me 5 questions to ask 3 real customers this week.
Summarize my customer in one sentence I can use in my messages.

Privacy

Before you paste anything into an AI, remove real people's details. Do not paste your customers':

full names
phone numbers
addresses
private account information

Verify

AI helps. You verify. What real customers tell you outranks any guess an AI makes.

Common mistake

The mistake

Choosing the customer you wish you had, instead of learning from the people who actually buy or show interest.

Do this instead

Start from the evidence: who has bought, asked, or recommended you? Describe those people first.

Key words

Checklist

Before you move on, confirm

I can describe who needs my offer most.
I can name the problem I solve.
I know at least one place where I can reach this customer.
I know how to test my assumptions with real people.

Verify

Check it against reality

Before you change your whole business because of an AI answer, or your own guess, talk to 3 real customers or people who could become one.

Ask why they bought from you, or what would make them buy.
Listen for the exact words they use to describe their problem.
Adjust your sentence with what you learned, not with what you hoped to hear.

AI helps. You verify.

In short

Three ideas to take with you

Your customer is not “everyone”: when you speak to all, nobody feels spoken to.
Focusing is not refusing; it is knowing who you speak to first.
A clear customer has four parts: who, problem, where, and why you. And it is checked with real people.
