# Customer profile concepts

> What a customer profile is, how it differs from a persona, a segment, and an audience list, and what separates a profile built from evidence from one built from assumption. Read this before filling in a profile brief.

A customer profile describes the kind of customer most likely to buy, stay, and grow with you. It is written once, named, and then referenced by name from every brief that targets it.

The reason it exists as its own document is repetition. A campaign brief that describes its audience in its own words produces a slightly different audience in the next brief, and a third version in the creative brief after that. Three teams then build against three pictures that nobody agreed to. Writing the profile once and pointing at it is what keeps them aimed at the same customer.

This page explains the thinking. The fill-in workbooks are the [B2B profile brief](/customer-profile-brief) and the [B2C profile brief](/b2-c-customer-profiles), finished profiles live in the [customer profile library](/customer-profile-library-overview), and the path from blank page to platform audience is [define a customer profile](/define-a-customer-profile).

## Profile, persona, segment, and audience list are four different things

These four get used interchangeably in conversation, and each one answers a different question. Keeping them apart is what stops a profile from turning into a target list or a character sketch.

| Term             | What it is                                                             | Example                                                                    | Where it lives                                                 |
| :--------------- | :--------------------------------------------------------------------- | :------------------------------------------------------------------------- | :------------------------------------------------------------- |
| Customer profile | The type of customer worth pursuing                                    | *Mid-market e-commerce companies losing margin to manual order processing* | [Customer profile library](/customer-profile-library-overview) |
| Buyer persona    | One individual inside that type, with their goals, objections, and day | *The operations manager who feels the pain and pushes for a fix*           | A separate persona document                                    |
| Segment          | A slice of people you already have, cut for analysis or targeting      | *Customers who bought twice in the last 90 days*                           | Reporting and platform tools                                   |
| Audience list    | The file of named companies or contacts                                | *A 4,200-row export uploaded to Meta*                                      | [Audience list store](/audience-list-store)                    |

<Warning>
  The distinction that causes the most trouble in practice is the last one. A list of named companies or contacts is a data file, and it belongs in the [audience list store](/audience-list-store) behind access control with its source and expiry recorded. The library holds descriptions. Mixing the two puts personal data in a folder built for reading.
</Warning>

## A profile is a type, not a customer

The temptation with any profile is to write one real account or one real person, because a specific example is easier to picture than a category. The cost shows up later: a profile written around a single customer produces messaging that fits that customer and nobody else who was supposed to be covered by it.

The useful width is a group narrow enough to picture and wide enough to hold the cluster of buyers who actually behave the same way. "Busy urban professionals who treat a good doughnut as an affordable everyday treat" describes a type you can target and measure. "Sarah, 34, marketing manager, loves oat milk" describes a character somebody invented.

## B2B and B2C profiles ask different questions

There are two workbooks because the buying situation differs.

| Aspect                     | [B2B profile](/customer-profile-brief)              | [B2C profile](/b2-c-customer-profiles)         |
| :------------------------- | :-------------------------------------------------- | :--------------------------------------------- |
| The subject                | A company                                           | A person                                       |
| The core filter            | Industry, size, business model, growth stage        | Age, life stage, income, location, values      |
| Who decides                | A buying committee with several roles               | The individual, sometimes influenced by others |
| What drives the purchase   | A problem with a cost attached                      | A desire, a want, or a moment                  |
| What triggers it           | A business event: funding, a new leader, a deadline | A mood, a time of day, an occasion, a season   |
| What good looks like after | Retention, rollout, expansion                       | Repeat purchase and word of mouth              |

Picking the wrong one is a recognizable failure. A B2C profile filled in for a business buyer collects demographics for someone whose employer is making the decision. A B2B profile filled in for a consumer product asks for a buying committee that does not exist.

<Note>
  Some businesses sell to both. Those are two profiles, not one profile with extra fields, and the [naming conventions](/customer-profile-naming-conventions) keep them apart with separate prefixes so a single filter can pull one kind.
</Note>

## Fit and timing are separate claims

A profile makes two different statements about a customer, and reading them as one is how a target list turns into a list of people who never respond.

**Fit** is structural. It says the customer's size, situation, and problem line up with what you sell. Fit is stable and changes slowly.

**Timing** is a trigger. It says something has just happened that opens a window: a funding round, a new leader, a deadline, a season, a mid-afternoon slump. Triggers fade, which is why they are worth acting on quickly or not at all.

A customer can match every attribute of the profile perfectly and have no reason to act this month. Naming the triggers separately tells the team what to watch for, and explains the accounts that fit the profile and stay quiet.

## Where a profile comes from

The strongest profiles are read backwards out of customers you already have. Pull your best accounts, then the ones that churned or turned out to be a bad fit, and look for what separates the two groups. That comparison produces facts. Asking the room who the ideal customer is produces beliefs, and both arrive on the page looking identical once they are typed up.

This is also why the sections on success and loyalty matter as much as the ones on who to pursue. A profile tuned only for the sale will happily bring in customers who sign, struggle, and leave. Defining what a good customer looks like after they buy points the profile at retention, and gives you a yardstick to correct it against later.

<Note>
  Finding a profile is research work: customer interviews, win and loss reviews, support tickets, and sales call notes. This framework does not teach that. What it records is the profile you arrived at, so it can be built from, targeted, and found again. See [what this framework covers](/what-this-framework-covers).
</Note>

## The part most often skipped is the insight

A profile that lists only attributes describes a customer completely and still gives a writer nothing to work with. Age, industry, and headcount place someone in a bucket. What they currently believe, doubt, or have been burned by gives a writer something to push against.

That belief is where an [angle](/angle-concepts) comes from. An angle sits at the meeting point of something true about the product and something the customer already thinks, and it cannot be written from a demographic. A profile without an insight produces creative aimed at an age bracket.

## Disqualifiers are the profile in reverse

Most profiles describe who to pursue and stop, which quietly treats everyone else as neutral. Some customers are worse than neutral. They match on the surface, absorb a long sales cycle or a large share of spend, and then either walk away or cost more to serve than they ever return.

Disqualifiers are the last section a team can fill in honestly, because they come from experience rather than theory. They are also the section that saves the most money, since they stop the same mistake from being made twice by someone who was not there the first time.

## A profile has a shelf life

A profile written from research and a profile written from assumption read exactly the same six months later, once the person who wrote it has moved on. Two habits keep that from happening.

* **Record where each claim came from** as you fill it in, the same way [positioning](/positioning) records evidence behind its reasons to believe.
* **Set a review date.** A profile that was accurate at launch describes a different buyer two years later, and nothing about the document announces when it stopped being true.

Versioning does the rest. When a profile changes, save it as the next version rather than editing over the old one, so the history of what you believed and when stays intact.

## What a customer profile is not

* **A target list.** The profile is the description. The list of named companies or contacts is an export, and it lives in the [audience list store](/audience-list-store).
* **A persona.** The persona is one individual inside the profile, with their own goals and objections.
* **An angle.** The profile is who. The [angle](/angle-concepts) is why they should care. One profile supports several angles.
* **A campaign audience setting.** Platform targeting is one expression of a profile, limited to whatever that platform can actually target on.
* **A segment of your existing customers.** A segment is cut from data you already hold. A profile describes customers you may not have yet.
* **Fixed.** It is corrected every time a customer turns out better or worse than the profile predicted.

## Where profiles sit in the rest of the framework

| Document                                                      | Uses the profile for                                  |
| :------------------------------------------------------------ | :---------------------------------------------------- |
| [Marketing campaign brief](/marketing-campaign-brief)         | Who the campaign targets                              |
| [Angle brief](/angle-brief)                                   | The person the proposition has to land with           |
| [Copy brief](/copy-brief)                                     | Who the writing addresses, and the insight to push on |
| [Creative brief](/creative-brief)                             | Who the concept has to land with                      |
| [Messaging](/messaging)                                       | The audience rows in the variation matrix             |
| [Platform CSV templates](/customer-profile-csv-template-meta) | The exported audience file                            |

The pairing that matters most is the profile and the angle. A profile with no angle produces creative aimed at a demographic. An angle with no profile produces a claim with nobody behind it.
