Building an ideal customer profile: how to choose the customers you can deliver the most value to.

By Nona Stabel and Carlijn Hofland ·

In short: An ideal customer profile (ICP) describes the type of organisation you can deliver the most value to and win most easily: sector, size, situation and the moment the problem becomes urgent. You build it from your best existing customers, not from wishes, and you state just as clearly who does not fit.

Ask a growing B2B company who it's for, and the answer is often: “actually, everyone in our market.” That sounds like an opportunity, but it works like a brake. Marketing writes a broad story, sales chases anything that moves, and the customers who fit best get no more attention than the ones who mostly cost time.

An ideal customer profile fixes that. This guide explains what an ICP is, how it differs from a persona and a target audience, and how to build one in six steps that doesn't end up in a drawer, but is used every week for qualifying, prioritising and marketing choices.

What is an ideal customer profile?

An ideal customer profile (ICP) describes the type of organisation you can deliver the most value to and win most easily. It's about the organisation, not the person: sector, size, structure, region, and above all the situation in which the problem you solve becomes urgent.

A good ICP is a choice, not a description of all your current customers. It helps you decide which opportunities come first, which accounts marketing and sales actively approach, and which enquiries you'd better refer elsewhere.

ICP, persona and target audience: the difference

  • Target audience: the broad market you operate in, for example “manufacturing in the Netherlands”.
  • Ideal customer profile: within that market, the type of organisation and the situation in which you deliver the most value, for example “family-owned manufacturers with 80 to 250 people that are starting to sell outside the Benelux for the first time”.
  • Persona or buying team: the people within that organisation who experience the problem, influence the choice and decide, each with their own questions and objections.

The order matters. Start with personas without an ICP, and you write good copy for the wrong organisations.

Why an ICP is the foundation of your commercial strategy

The ICP is the second choice in a commercial strategy, right after an honest picture of where you stand. Everything after it builds on it: the positioning (why does this type of customer choose us?), the priorities, the channels and the agreement between marketing and sales on what a good lead is.

Without an ICP, marketing and sales often measure different things. Marketing delivers leads that fit on paper, sales doesn't think they're good enough, and nobody can say who's right. More on this on the page Many leads, few deals.

Six steps to an ideal customer profile

Before you start: gather what's already there

You don't need expensive data. Start with a list of your customers from the past two years, with revenue and margin per customer, how long the sale took and whether they stayed. Put lost proposals and customers who left next to it. That's enough to see patterns.

Step 1. Decide who your best customers are

Decide up front how you recognise a good customer, or the customer who shouts loudest wins. Use four to five criteria and give each customer a simple score:

  • Value: revenue and above all margin, over the whole relationship.
  • Speed: how short the sales cycle was.
  • Retention and growth: stayed, expanded, or referred others.
  • Fitting work: the problem you solve best, without a lot of customisation or hassle.
  • Energy: the collaboration works, for both sides.

Take the ten to twenty customers with the highest score as your starting point. Talk to a few: why did they choose you, and what was going on at the time?

Step 2. Find the pattern in the organisation

What do those best customers have in common? Look at the hard characteristics: sector or niche, number of employees or revenue, region, ownership (family business, private equity, part of a group), and how the organisation is set up, for example whether there's already a marketing team or a sales lead.

Be as specific as the pattern allows. “Manufacturers” is a target audience; “technical manufacturers with 50 to 250 people and their own sales team, but no marketing department” is a profile.

Step 3. Name the situation and the triggers

Organisations with the same characteristics don't all buy at the same moment. The difference is the situation. Which event made your best customers start looking? A new managing director, an acquisition, a new market, a missed revenue target, a big customer lost, or a website that no longer fits.

Those triggers are the most useful part of the ICP. They tell sales when a conversation makes sense, and marketing what it should be about.

Step 4. Map the buying team

In B2B, one person rarely buys alone. For each ICP, capture who experiences the problem, who influences the choice, who decides and who can block it, and what question each of them has. A commercial director wants to know whether it pays off; a finance director what it costs and when it earns itself back; a marketing manager whether it fits the team.

Step 5. State who does not fit

An ICP without exclusions is a wish list. Name the signals that show an organisation does not fit: too small to execute it, only looking for the lowest price, no decision-maker at the table, or a question that belongs with a different kind of partner. It feels like leaving revenue on the table, but it gives sales time for the opportunities that do fit.

Step 6. Test it and make it usable

Put the ICP next to the current pipeline: how many open opportunities fit, and how do they perform compared with the rest? Then put it where the work happens:

  • Sales: a short checklist for qualifying, with the triggers and the exclusions.
  • Marketing: the topics, channels and examples this type of customer responds to.
  • Account list: a list of concrete organisations that match the profile, for targeted outreach.
  • Leadership: a fixed moment each quarter to check whether the profile still matches what comes in.

Example: an ideal customer profile on one page

An example for a fictional software supplier of sixty people that works mainly in logistics (the same company as in the guide Building a commercial strategy). All details are made up.

  • Organisation: logistics service providers with 100 to 500 employees and more than one site, in the Netherlands and Belgium.
  • Situation and triggers: they're opening a new warehouse, or losing a customer because of delivery errors.
  • Buying team: the operations director experiences the problem, the IT manager influences, the managing director decides, the finance director can block.
  • Why they're the best fit: highest margin, a sales cycle of three to four months, and often expansion to a second site after a year.
  • Who doesn't fit: companies with one site and fewer than 50 employees, and parties mainly after a price comparison.
  • How it's used: a list of 120 organisations that match the profile, a qualifying question about new sites in every first conversation, and content about implementations without downtime.

Common mistakes

  • The ICP describes who you want, not who you win. Start from the data on your best customers, not from the customers who look good on the website.
  • Only hard characteristics. Sector and size without situation and trigger say nothing about the moment of buying.
  • No exclusions. Then nothing changes in practice.
  • Too many profiles. Start with one, two at most. Every extra profile needs its own story and its own attention.
  • The ICP stays with marketing. If sales doesn't use it for qualifying, it's a document, not a choice.

The test: is your ICP sharp enough?

  • Can marketing and sales explain it the same way in two sentences?
  • Are there recognisable organisations that fall outside it?
  • Does it include a situation or trigger, not just sector and size?
  • Do you know who's in the buying team, and what each of them wants to know?
  • Does it match your best customers of the past two years?
  • Could you use it tomorrow to make a list of twenty concrete organisations?

Do it yourself, or together?

You can take the six steps yourself, if someone gathers the customer data and leadership takes the time to really choose. If it proves hard to settle on one profile, or it gets stuck on a difference of opinion between marketing and sales, an outside view helps. In the Growth diagnosis we look at where growth gets stuck; a sharp ICP is often one of the outcomes.

Frequently asked questions about the ideal customer profile

What's the difference between an ICP and a persona?

An ICP describes the organisation and the situation in which you deliver the most value. A persona describes a person within that organisation, with their role, questions and objections. Start with the ICP; the personas follow from it.

How many ideal customer profiles should you have?

Start with one, two at most. Every profile needs its own story, its own examples and its own attention from sales. More profiles feel safe, but make the choice broad again.

What if we don't have many customers yet?

Then use the customers and projects you do have, plus the team's experience from previous jobs. Make a first version, call it a hypothesis, and test it in the first twenty conversations.

How often do you update an ICP?

Check every quarter whether the profile still matches what comes in and what you win. Really change it when something fundamental changes: a new offer, a new market or a different type of customer that turns out to fit better over time.

Is an ICP only for large companies?

No. Especially for organisations of 15 to 250 people, with limited time for marketing and sales, a sharp ICP pays off: less energy spent on opportunities that don't fit, more on the ones that do.
