Know Who Your Customer Is: The Ideal Customer Profile for Solo Founders

Someone asks who your product is for, and you say everyone. It's the honest answer. You built something genuinely useful and you can see six different people it would help. Saying "everyone" feels generous, even confident.

It's also the sentence quietly costing you customers. When your customer is everyone, your message is for no one, you don't know which room to walk into, and you can't tell whether the person in front of you is worth the next hour.

This is the part most founders skip because it feels like it slows them down. It's the part that makes every message after it land. Not a 30-field template. One page of the few things that actually predict who buys, built from what you can see people say and do, narrow enough to feel uncomfortable.

Why the enterprise ICP template is built for someone who isn't you

Most ICP templates are written by data aggregators. The whole point of them is to sell you access to a database, so they're built around the fields a database can filter on: job title, company size, industry, revenue. That's perfect if you want to buy a list of ten thousand names and blast all of them. It's the wrong tool entirely for a founder with zero customers and an afternoon.

Those hard fields are quantitative. Your real customer is qualitative. A founder isn't looking for a job title, they're looking for a person with a particular way of thinking, a specific thing they're stuck on, and a habit of saying so in public. Fill in the enterprise form and it quietly funnels you into spray-and-pray: more names, worse fit, a message so generic nobody replies. You end up busy and nowhere.

If you want the ground-level version of what an ICP even is before we reframe it, here's the plain-English definition. This page is about the version a solo founder can actually act on.

Which five things actually belong in a solo founder's ICP?

Cut the form down to what predicts a reply. In practice that's about five soft fields, not thirty hard ones:

Where they already spend time. The exact rooms, not "online". A subreddit, a Discord, the comments under a certain kind of post. If you can't name the room, you can't show up in it.

How they talk about the problem. The words they use, not the words you use. You solve "customer research"; they wrote "I have no idea who to even message." Match their language and half the work of a first message is done.

What they're visibly frustrated by. Something they've said out loud this week, in a post, a comment, a bio. A live frustration is a raised hand. A demographic isn't.

Their values and personality. The soft correlates no template has a field for. When I helped build the ICP at Plastic Bank, our thesis was "sustainability director, company of 250 to 500, this revenue." We did a deep dive on who'd actually bought, and the correlation with that thesis was essentially zero. What did correlate was personality: avid lovers of the ocean, humble people, often a bit older, often having lived and worked remotely across a few countries. None of that fits in a firmographic filter, and all of it is what let us find more of them.

What they do, not who they are on paper. Have they posted about this. Have they commented. Is it in their bio. Job title is at best a tie-breaker. Behaviour is the signal.

Notice these are open questions, not dropdowns. That's the point. You're profiling a person you'd recognise in a comment thread, not assembling a filter query.

Does niching down really shrink your market?

It feels like it should. Speak to a narrower person and surely you reach fewer people. The counterintuitive truth is the opposite: the more specific your customer, the more people end up relating to you. Jason Cohen calls this "speaking to Carol." His finding is that when you write for one sharply drawn person, your effective market is at least 10x larger, not smaller.

The mechanism is relatability. Cohen's example is Subaru, who deliberately marketed to one specific, unusual segment and then grew faster than any other carmaker for a decade, still selling mostly to people outside that segment. Someone who matches three of your five traits still sees themselves in a message written for all five. They translate it to their own situation. A vague message written for everyone gives no one anything to see themselves in.

So narrow it down until it feels almost too tight to be worth it. That discomfort is the signal you've gone specific enough to recognise the person when they appear, and specific enough that they recognise themselves. Narrow is not the limitation. Narrow is the unlock. When you're ready, this is where niching down earns its own page.

How do you know your ideal customer profile is wrong?

Watch the speed, not the conversion rate. The tell isn't "they said no." The tell is that everything drags. You're writing long explanations, they're asking a pile of questions, they're not sure what the thing is worth to them, and it takes many messages or a long call to get there. When you've got the right person and the right words for them, it's fast. They arrive already understanding what you do.

I saw both sides of this. At Baseline Media, when we reached a client whose ICP we'd nailed, the call opened with "that's a service I want, and I know you can do it." No convincing. That speed told us we'd profiled them perfectly. Then at MyPip I got it wrong: I built for the SDR chasing a quota, someone who wants to send the maximum number of messages and doesn't care much about quality. That field is brutally competitive, and worse, the people actually saying yes weren't those people at all. They were founders and early marketers who wanted to talk about a product they'd built and had no natural way to. I only found that by reading who replied. The wrong ICP wasn't losing me sales so much as pointing me at the wrong ocean entirely.

If you want to hear what a fast yes sounds like in the conversation itself, here's how a fast yes actually sounds on a call.

If MyPip builds your ICP from your website, why understand it yourself?

MyPip reads your site and drafts a first ICP in seconds, so it's fair to ask why you'd think about it at all. Because that draft is a starting block, not the finished thing. It's Michelangelo's marble before the chiselling. We take the first snapshot from your marketing copy, start finding people, and then as replies come in and some convert, the picture sharpens into who your customer really is.

If you never engage with that, you stay stuck with whatever your homepage happened to say on day one, which may be aimed at the wrong person, and you'll never notice the blue ocean sitting next to you. The founders who get value from it treat the generated profile as a hypothesis to chisel, not a form that's finished. The tool gives you the base and does the searching. The judgement about who this is really for is still yours, and it's the highest-leverage thinking you'll do.

The two things everything else on this page hangs off: profile the person by what they say and do, not what a database can filter, and then go find them and say something that lands.
