Ideal customer profile for B2B SaaS: a template and a worked example.
By Nouman, founder · 7 October 2026
An ideal customer profile (ICP) is a written description of the kind of company most likely to buy your software and succeed with it: its industry, its size in the unit that matters, the situation that makes the problem urgent, who feels the pain, who signs, and how it buys. A good one also names the segments you're leaving out and why. If you can't find companies from it, or it doesn't exclude anyone, it isn't finished.
ICP or buyer persona?
Both, in that order. The ICP describes the company: which ones to go after. A buyer persona describes the person inside it: their role, what they're measured on, what makes them act. Get the company wrong and the best persona in the world is writing to the wrong building.
The nine fields that matter
- Industry. The narrowest industry where you already have customers who succeed. "Utilities" is too wide; "contractors who inspect utility assets" is a segment.
- Size, in the unit that matters. Not always employees. Field technicians, locations, transactions or engineers often predict fit better. Give a range, and say what happens just outside it.
- Situation and trigger. What has just changed for them that makes the problem urgent now, and where you can see that change from the outside.
- The problem, and today's workaround. What they do instead of using you: a spreadsheet, a generic tool, a person. Your real competitor is usually this.
- Who feels the pain. The role that suffers when the problem isn't solved.
- Who holds the budget and signs. If it isn't the same person, write down who it is and how a decision gets made. This is where most segments quietly fail.
- How it gets bought. Weeks or quarters, a card or procurement, a subscription or a project.
- Evidence you can show. Customers of exactly this shape who succeed with you. Without them, the ICP is a hypothesis, and you should say so.
- Who you are excluding, and why. The segments that look attractive but fail one of the fields above. Written down, so nobody drifts back into them.
The worksheet
Copy this into a document and fill in one per candidate segment. Two or three candidates is plenty. Then compare them on the fields where they differ.

The tenth line is the one people skip. Write down the evidence that would make you drop this segment, so you'll recognise it when it arrives.
A worked example
Stannary Systems is an invented company, used in our published sample diagnostic. It is not a client.
Stannary sells software for scheduling, evidencing and reporting regulated inspections on utility infrastructure. Its early customers came from the founders' contacts, and that source has run out. Two segments both have the problem it solves:
- Chosen: independent inspection contractors with about 20 to 200 field technicians. The operations director feels the pain and usually holds the budget, so one person can say yes. It's bought in weeks, on a monthly subscription. They're findable from the outside, because framework and term-contract awards are published, and so are the job adverts a contractor runs after winning one. And Stannary has two customers of exactly this shape who pass their audits with it.
- Excluded: in-house compliance teams at the asset owners. The compliance manager feels the pain, but the budget sits with a different director who owns the asset-management system, and any change becomes an integration project measured in many months. No email to the person in pain can fix who holds the budget.
Notice what decided it. Both segments had the problem. The difference was who signs, how it's bought, whether they can be found specifically, and whether there's evidence to show. That's why those fields are on the worksheet. Read the full diagnostic, including the two further cuts inside the chosen segment
Four ways an ICP goes wrong
- It describes everyone. "B2B companies with 50 to 5,000 employees" includes most of the economy and excludes nobody.
- It stops at the pain. Plenty of people feel a problem they can't buy a fix for. The budget field is where it gets real.
- It can't be found. If no list, signal or public record identifies these companies, the ICP can't drive outreach.
- It's never revisited. Every lost deal and every reply is evidence. Look at the ICP again after the first few weeks of real conversations.
What to do with it
Build a short list from it, write to the people who own the problem, and count what happens with its denominator. How to get the first 10 customers · How to build the pipeline
Writing the ICP is the first thing our diagnostic does, with the segments to exclude and the evidence that would change the call. How the diagnostic works
