I spent most of last week annoyed at my own AI, which is a rough thing to say out loud, considering that helping people train their AI to sound like them is my literal job. Theoretically I should have one of the best-trained tools out there.
The outputs weren’t wrong, but they did feel flat. And creating content stopped being fun, which is usually the first symptom of something broken upstream.
So I blocked a couple of hours a day for two days and combed through everything that feeds what I call my brand brain. Documents, skills, instructions, every file I hand my tools.
My origin story was fine. That’s history, it already happened, it doesn’t move. What had moved was my persona.
The question most people can’t answer
Open your feed and scroll your last handful of posts. Could you describe, in detail, exactly who each one was written for?
Most people can’t. They reach for demographics instead. Thirty to fifty, female, married, homeowner. Those are data points. That’s a bracket, and you cannot have a conversation with a bracket.
Your niche is a name, not a demographic.
That distance between naming a category and describing a person is where most content dies. It was aimed at everyone before the first word got typed.
What is an ideal client persona, and why does it matter more now?
An ideal client persona is a detailed profile of one specific person you want to work with, built from real clients you have actually served rather than market research. It captures their fears, decision drivers, internal monologue, and where they spend their attention, in their own language. It matters more now because AI takes generalization and flattens it. Feed a vague persona in and you get slop out, faster than you could produce it yourself.
That word is doing real work. Every generic post in your feed right now is a tool filling gaps its owner never filled.
The fix is upstream of the prompt.
Why your persona expires and your story doesn’t
Before AI was a thing, I spent six years ghostwriting for top producers in the mortgage space. The only way to be any good at that was to know them well enough that I could think and talk like them.
That’s the whole mechanism, and it hasn’t changed. The tool is new. The requirement isn’t.
Your origin story is a fact about your past. Write it down once and revisiting it every quarter is a waste of an afternoon.
Your persona describes who you want in front of you right now, and that changes every time you finish a project you loved and every time you finish one you didn’t.
Mine had shifted and I never went back and wrote it down. So my AI was doing precisely what I asked. It was writing beautifully to a person I had stopped taking on.
The Grand Central problem
Picture yourself standing on a chair in Grand Central Station at the busiest commute time of the day, shouting about who you are and what you sell.
Nobody stops. Nobody pays attention. Nobody cares.
That’s spray and pray, and it’s how a lot of people are running their social media right now. We throw things out there and then wonder why it fell flat.
Content that speaks to everyone speaks to no one. I know that lands badly if you’re in sales, because you were trained to think anyone who meets the parameters is someone you could help, and turning people away feels backwards.
The turning-away isn’t real. You’re narrowing who you write to, not who you serve.
How to define your ideal client persona in three steps
Step one: start with three real people
Pull your last twelve months of clients. Find two or three you absolutely loved working with, the kind where if you had twenty of them your job would be a dream to wake up and do.
Real names, real engagements, in front of you. Not hypotheticals and not the client you wish you had. Go to real clients, because you can remember the actual conversations you had with them.
Then give the composite a name. One name, one person. The name is a writing instrument and you never publish it. It exists so that every time you sit down to create, you’re writing to someone instead of at a category.
Questions to work through:
- Which engagements last year did I genuinely enjoy, and what did those people have in common?
- Which client would I decline if they came back, and what specifically made it a bad fit?
- Why did they choose me over somebody else?
- What were their hesitations before they said yes?
Step two: interrogate her until it’s uncomfortable
Get honest about who she is and why you love helping her. If the answers come easily, you’re describing a category again.
Answer these out loud before you type anything. Talking surfaces detail that typing sands off.
Questions to work through:
- What is keeping her up at night, and what is stressing her out, in the words she’d use rather than the words a marketer would use?
- What would a win look like for her? What would a loss look like?
- What are the internal conversations she’s having with herself?
- Who influences her decisions?
- What has she already tried that didn’t work, and what did it cost her in money, time, or confidence?
- What is she struggling with that she would never say out loud on a call with me?
Then the layer almost everyone skips, because it decides where you show up and not just what you say:
- Where does she hang out, and how does she learn?
- Does she engage with technology? Does she use AI?
- Long-form or short? Reading or video?
- What was her communication preference, and how often did we actually talk?
Step three: write her words, then test the difference
Write her internal monologue in her words, not your marketing summary of her problem. The actual sentences she would say.
The rule I hold myself to: if she didn’t say it, it doesn’t go in that section. My own interpretation lives somewhere separate and clearly labeled, because the moment those blur you’re writing to your idea of her instead of to her.
Pull the real language from wherever it lives. Discovery call notes. Text messages. The line in an email that made you think, that’s exactly it.
Then trust but verify. Upload the updated document, create a new piece of content, and read it against something you wrote before the update. That gap is what a stale persona has been costing you.
When I did this, my reaction was that I didn’t know why I hadn’t done it months earlier. One change to the system and the quality came back.
Questions to work through:
- What has a client said to me, word for word, that captured the problem better than I could?
- What phrase do I hear on discovery calls over and over?
- Which of my notes about her are things she said, and which are things I concluded?
What a finished persona actually looks like
Here’s one built out loud, so you can see the difference between a bracket and a person.
College-aged women just entering the workforce. First job, renting, looking to buy in the next year. Scrolling TikTok and Instagram. Into fashion. Heavily influenced by their friends and still young enough to be taking advice from mom and dad. Probably dating, maybe a serious boyfriend by now.
Now you can write. Whatever you sell, you can speak to her, and when you bring in your own story about how you got into this work it lands like you’re talking to one person on the other side of the screen rather than broadcasting.
The goal is that she reads it and thinks, that is me, I can relate. That’s when a follow or a comment or a reply actually happens.
Build a few, then look for the through-line
You are not limited to one persona. You will most likely have several, and you probably should.
Profile a few of them, and here’s the part that pays off: you’ll start noticing the commonality between them. A general baseline that runs underneath all of them.
That through-line is worth more than any single profile, because it’s the thing that lets you write one piece that lands with several people without flattening back into writing for everyone. You can also rotate which persona you’re writing to and keep the whole set warm.
The other thing that surfaces once you’ve profiled a few is how you are uniquely positioned to help them, and why. That’s not a separate branding exercise. That’s your story, aimed. Connection and empathy in your content come from that alignment, not from better hooks.
The prompt to get started
Copy this into Claude, ChatGPT, or whatever you use. It makes the AI interview you rather than generate a persona for you. A tool that invents your ideal client is producing fiction. A tool that pulls out what you already know from working with real people is doing something useful.
I want to build a detailed ideal client persona based on real
clients I have worked with. Do not generate a persona for me and
do not fill in gaps with assumptions.
Your job is to interview me, one question at a time, and wait for
my answer before asking the next one. Push me for specificity when
my answers are vague. If I say something general like "she's
overwhelmed," ask me what that looks like on a Tuesday.
Start by asking me to name two or three real clients from the past
twelve months I would happily take twenty more of, and what those
people have in common.
Then work through these areas, one question at a time:
- what keeps her up at night and what stresses her out
- what a win looks like for her, and what a loss looks like
- the internal conversations she is having with herself
- who influences her decisions
- why she chose me over someone else, and what her hesitations were
- what she has already tried that failed, and what it cost her
- where she hangs out, how she learns, whether she uses AI,
and whether she prefers long-form, short-form, or video
When we finish, produce a document with three clearly separated
sections:
1. VERBATIM - things my clients actually said, quoted exactly
2. OBSERVED - patterns I described from real experience
3. MY INTERPRETATION - conclusions you or I drew, labeled as
interpretation and not as fact
Keep those three separate. Do not blend them.
The three-section split is the part people skip and the part that keeps the file honest six months from now. Verbatim is evidence. Interpretation is a guess wearing evidence’s clothes.
Put it on the calendar
Your origin story is fine to leave alone for years. Your personas get looked at whenever you finish a project that changes how you feel about the work, and at least a couple of times a year regardless.
Set the reminder now, while you still remember how annoying the stale version was.
Frequently asked questions
How many personas should I have?
Several, and you should build them deliberately rather than letting them accumulate. Start with one built properly from real clients, then add a second and a third. Once you have a few, look for the baseline they share. That through-line is what lets one piece of content land with more than one of them.
Can I just let my AI figure out my audience over time?
It will build something, and that something is assembled from your prompts and the internet’s assumptions about your industry. Memory is a record of what you happened to mention, not a documented strategy. A written persona you control beats an inferred one you can’t inspect or correct.
Doesn’t niching down this far shrink my audience?
It shrinks who you write to, not who reads. Specific content travels further because a real person recognizes themselves in it and sends it to someone else. And since you’ll have several personas rather than one, you’re narrowing each piece rather than narrowing your business.
What if I don’t have clients I can point to yet?
Use people you have had real conversations with about the problem you solve. Discovery calls, coffee meetings, someone who asked you a question at an event. You need real language from real humans, not a signed contract.
Go update the file
My content stopped sounding like me because I stopped telling my AI who I was talking to, and then got frustrated when it guessed.
So go back to the question at the top. Scroll your last few posts and name who each one was for. If you couldn’t answer it ten minutes ago, you can this week.
Give your persona a name. Get as uncomfortably clear as you can about who she is. Upload it, write one new piece of content, and see whether the output changes. I have a hunch it will.
And if you’re stuck further back than that, stuck on your story, on what makes you different, on who you’re even good at helping, that’s the front half of Brand Builder. Ninety minutes, I ask the questions, you talk, and you leave with her written down along with the system that uses her.
