In short
- An ideal customer profile (ICP) describes the company – not the person – that benefits most from your offering and is most valuable to you.
- You derive a good ICP from your best existing customers: what do they have in common, how can you recognise them from the outside, and whom do you deliberately exclude?
- What matters is that every criterion can be verified – via registers, websites or job ads. Only then does the profile turn into a list of real companies.
What is an ideal customer profile?
The ideal customer profile – ICP for short – describes the type of company that needs your offering most urgently, buys fastest and stays longest. It is the foundation of your market analysis: the ICP determines which companies belong to your addressable market.
ICP vs. buyer persona: what is the difference?
| Ideal customer profile | Buyer persona | |
|---|---|---|
| Describes | A company | A person within the company |
| Typical attributes | Industry, size, region, business model, organisation | Role, goals, challenges, objections |
| Answers | Which companies do we target? | Whom do we speak to there – and how? |
| Result | A list of target companies | Messaging and call scripts |
The two belong together: the ICP determines which companies you approach; the persona helps you decide whom to reach there and with what message.
How to build your ICP in seven steps
- Select your best customers. Pick five to ten customers you would like more of: high revenue, short sales cycles, low service effort, good collaboration.
- Find what they have in common. Compare industry, size, region, business model and organisation. Often a pattern emerges that goes beyond industry – such as their own field sales force or multiple locations.
- Make attributes verifiable from the outside. Translate each attribute into something that can be recognised publicly: in the commercial register, on the website or in job ads. ‘Innovative’ cannot be verified; ‘hiring field service technicians’ can.
- Define exclusions. Whom do you deliberately not want to approach? Existing customers, competitors, pure resellers, group subsidiaries with centralised purchasing.
- Weight the criteria. Not every attribute is equally important. Weight the criteria and combine them into a fit score – so companies can be compared and prioritised.
- Add signals. Which events show that a matching company has a need right now? Find out more in our guide to buying signals in B2B sales.
- Test and refine. Check a sample of 20 to 50 companies against the profile. Do they really fit? Refine the criteria – and repeat this regularly using feedback from your sales team.

| Field | Key question | Example |
|---|---|---|
| Industry | Which industries are your best customers in? | Machinery and plant engineering, building services |
| Size | How many employees, what revenue? | 50–1,000 employees |
| Region | Where can you deliver and provide support? | Germany, Austria, Switzerland |
| Business model | How does the customer make money? | Selling equipment plus maintenance contracts |
| Visible attributes | How can you recognise them from the outside? | Own field service team, vacancies for service technicians |
| Exclusions | Whom do you not approach? | Existing customers, pure resellers, competitors |
| Target roles | Who decides, who uses it? | Head of service, managing director |
| Signals | What indicates an acute need? | New field service vacancies, website visits, new head of service |
Common ICP mistakes
- Too broad: ‘Mid-sized companies in Germany’ is not a profile but a population.
- Not verifiable: attributes such as ‘digitally minded’ cannot be identified in any source and lead to gut-feeling lists.
- Based on wishful thinking: an ICP comes from your actual best customers, not from the logos you would like to have.
- Never revised: markets and offerings change. Review your ICP at least once a year and after every major product change.

Frequently asked questions
What is an ideal customer profile (ICP)?+
An ICP describes the type of company that benefits most from your offering and is most valuable to you – with verifiable attributes such as industry, size, region, business model and organisation, plus deliberate exclusions.
What is the difference between an ICP and a buyer persona?+
The ICP describes companies; the buyer persona describes people within those companies. The ICP defines which companies you approach; the persona helps you decide whom to reach there and with what message.
How many customers do you need to define an ICP?+
Five to ten particularly good existing customers are usually enough to identify a reliable pattern. More important than the number is that they really are your best customers.
How do you turn an ICP into a list of target companies?+
By translating every criterion into a publicly verifiable attribute – for example via registers, websites and job ads. Each company can then be checked individually against the profile and given a fit score.
