What Is an Ideal Customer Profile (ICP)?
Updated · Team Fonda
Short answer
An ideal customer profile (ICP) is a short description of the type of customer who has the problem you solve most sharply, can pay for a solution and is realistic for you to reach. In business-to-business selling it describes a kind of company, not an individual person.
Key takeaways
- An ICP describes the account you want: the type of company or household, not one named person.
- A good ICP is narrow enough that you could build a list of matching customers this week.
- Before you have customers, your ICP is a guess. Interviews turn it into evidence.
- It tells you who to say no to, which saves a small team the most time.
What an ideal customer profile means in plain words
Not every possible customer is equally worth chasing. Some feel the problem every day, already spend money on it and decide quickly. Others are mildly interested and take months to say no. An ICP writes down what the first group has in common so you can find more of them.
The term is used most by companies that sell to other companies. If you are unsure which side you are on, see B2B vs B2C. Consumer businesses can use the same idea by describing a type of household or situation, such as "renters with a dog and no garden".
What goes into an ICP
| Attribute | Question to answer |
|---|---|
| Industry or type | What kind of business or household is it? |
| Size | How many staff, locations or customers do they have? |
| Location | Where do they need to be for you to serve them? |
| Trigger | What recent event makes the problem urgent now? |
| Current solution | What do they use today, and what does it cost them in money or time? |
| Ability to pay | Is there a budget, and who controls it? |
| Reachability | Where can you find a list of them or get in front of them? |
ICP template
Our ideal customer is a [type] with [size] in [location] that has just [trigger], currently handles the problem with [current solution], and can be reached through [channel].
A worked example
This is a made-up example. Say you are building rota software, a tool for planning staff shifts. A first attempt at an ICP might be "restaurants". That is far too wide to act on. After ten conversations you narrow it:
- Type: independent cafes and casual restaurants, not chains.
- Size: 8 to 25 hourly staff across one or two sites.
- Trigger: opened a second site or lost a manager in the last six months.
- Current solution: a spreadsheet and a group chat, taking the owner a few hours a week.
- Ability to pay: the owner decides alone and already pays for a till system monthly.
- Reachability: local hospitality groups and walking in during the quiet mid-afternoon.
Now you know who to contact on Monday, and you know that a 200-seat hotel restaurant is outside the profile, however keen it sounds.
Why it matters for a first-time founder
You need an ICP earlier than most people think: before your first customer interview, because you have to decide who to interview. At that point it is a hypothesis. Each conversation either supports it or tells you to redraw it, which is the core of customer discovery.
The ICP then shapes several later decisions. It defines the segment you count when you calculate TAM, SAM and SOM. It is the first box on a lean canvas. And it is the starting point of your go-to-market strategy. Fonda's journey includes an Interviews step in the Validate phase, where you test your guess about the customer with real people before you get a Verdict.
Common mistakes
- Describing who you wish would buy. Large, famous customers look good on paper but are often slow and hard for a new company to win.
- Making it too broad. If the profile matches most of the market, it is not helping you choose.
- Using only demographics. Size and industry matter less than the trigger that makes the problem urgent.
- Never updating it. Revisit the ICP once you have paying customers and see who stays, pays on time and refers others.
- Confusing it with a persona. The ICP picks the account. The persona describes the person inside it.

Frequently asked questions
What is the difference between an ICP and a buyer persona?
An ICP describes the kind of company or household you want as a customer. A buyer persona describes a person within it: their role, goals and worries. You use the ICP to decide which accounts to pursue and the persona to decide what to say to the people there.
How do I create an ICP with no customers yet?
Write your best guess, then test it. Interview 10 to 15 people who match the guess and note who has the problem most often, already pays for a workaround and wants to hear back from you. Redraw the profile around them.
Can a business have more than one ICP?
Yes, but start with one. Each profile needs its own message and channel, and a new business rarely has the time to do two well. Add a second when the first is producing customers steadily.
How detailed should an ICP be?
Detailed enough that two people reading it would agree on whether a given prospect fits. A short paragraph or six to eight bullet points is usually enough.
