Everyone could buy from you, but you build for one. A five-part scorecard, a fill-in paragraph for describing her, and how to save it so AI writes for her too.
To find your ideal customer, pick one specific person whose problem is urgent, who you can reach this week, and who you'd happily serve again. Then write her down in one paragraph you could hand to anyone, including AI. Lots of people could buy from you, but you build for one, and the choice holds for the next few months, not forever.
Picture your current list of possible customers. Small business owners. Moms. Maybe teachers. Also that dental office your cousin mentioned, because they said they'd "totally be interested."
Every name on that list is a real possibility, which is exactly why crossing any of them off feels like throwing away money you haven't made yet. So nobody gets crossed off. And then the quiet costs start showing up. Your website copy turns into oatmeal so it won't offend anyone. Your feedback contradicts itself because the teacher and the dentist want opposite things. You spend your evenings rewriting the same offer five different ways in five different DMs.
Trying to serve everyone doesn't protect your options. It just spreads your few hours so thin that none of them land.
This isn't only a small-business problem. A young company with few people and not much money often faces a version of the same fork: sell to small businesses, or chase big companies? Big companies look better on paper. Bigger contracts, impressive logos, a nice slide for investors.
But big companies also bring long sales cycles, committees, custom requests, and procurement forms that eat a quarter. The startups that survive that stage tend to pick the customer whose problem is most urgent and who fits what they already make without bending it out of shape, not the one that looks most impressive. They say no to good-looking customers so they can serve the right ones well.
Your version is smaller and has more school pickups in it, but the trade-off is the same. The most impressive customer isn't automatically the right first one.
Score each group you're considering, from one to three, on five things:
Add it up. The winner isn't always your favorite, and it's rarely the loudest group online. It's the one where the problem is real, the door is open, and the work fits your life.
If you haven't separated your audience into groups yet, start with finding your target market, then come back here to zoom in on one person.
A customer you can't describe is a customer you can't write for. Fill in a paragraph like this, ideally using words you've heard real people say:
She is [situation]. Her week looks like [one specific detail]. She's already tried [what she's tried], and it didn't work because [why]. What worries her most is [worry]. She'd describe the problem as "[her exact words]." What she wants instead is [result], and she'd know it worked when [sign].
The exact-words part matters most. "I want to grow my business" is a guess you made up. "I post every day and the only person who likes it is my aunt" is a person. If you don't have lines like that yet, have two or three conversations first; finding a problem worth solving walks through how to run them without fishing for compliments.
Here's an example from a meal-planning newsletter: "She's a mom of two under five who works three days a week. Dinner happens in the eleven minutes between bath time and a meltdown. She's tried meal kits and abandoned them because the kids wouldn't eat half of it. She'd describe the problem as 'I'm so tired of deciding.'" You can already see what to write for her, and what to leave out.
AI sounds generic for a simple reason: it doesn't know who you're talking to. Ask it for an email "for my customers" and it writes to the average of everyone, which is to say no one. Give it your paragraph first and the examples, objections, and next steps get noticeably more specific, because now there's a person to tailor them to.
Better still, save the paragraph so you don't paste it every time. As of October 2026, Claude, ChatGPT, and Gemini all let you save reusable instructions, and all three call them skills (Claude plans, ChatGPT skills and plugins, Gemini release notes). ChatGPT and Claude also have projects, which keep related chats and files together so the same context carries across ongoing work (ChatGPT projects). Buttons move and some features are still rolling out by plan and country, so look for the label rather than memorizing where it lives.
Once she's saved, AI can help you:
What stays yours: choosing her in the first place, deciding who you'll say no to, and noticing when she changes. AI will cheerfully write to whoever you describe, even if you described the wrong person. It's a very good writing partner and a terrible judge of your market.

Choosing her isn't a lifetime contract. It's a decision for the next stretch of work that gets you clearer feedback, sharper copy, and a much better idea of who should come next. Everyone else can wait in the parking lot for a minute. They'll still be there. For more on positioning and voice, see how we approach building a brand people care about.
Score the groups you could serve on how urgent their problem is, how easily you can reach them, whether they already spend time or money on it, how well it fits what you offer, and whether you'd enjoy the work. Pick the top one and describe one person in that group in a single paragraph, using words real customers have said.
A target market is a group of people with a shared situation. An ideal customer is one specific person inside that group, described clearly enough that you could write a message just for her.
You learn quickly and adjust. Choosing an ideal customer is a decision for the next few months, and serving one group well gives you clearer feedback than serving everyone a little.
Rarely, in the early stage. A focused message attracts the right people faster, and others who are close enough often still buy. The bigger risk is a vague message that nobody recognizes as meant for them.
Write a one-paragraph description of her and give it to AI before you ask for anything, or save it as reusable instructions. Then use AI to draft copy for her, predict her objections, and sort your conversation notes, while you keep the final call on who she is.
