How to Define Your ICP in 15 Minutes (With a Template)
A practical ideal customer profile template for B2B founders. Define your ICP in 15 minutes, with fields, examples and disqualifiers you can filter on.

An ideal customer profile (ICP) describes the type of company that gets the most value from your product and is most likely to buy, stay and pay. To define one quickly, look at your best existing customers or conversations, write down what they have in common (industry, size, location, model, trigger events) and list who you'll say no to. Use the template below and you'll have a working ICP in about 15 minutes.
Most founders either skip the ICP entirely ("we sell to everyone") or spend a month on a 30-page persona deck nobody reads. Both are expensive. What you actually need is one page, written so every line can be used to filter a list.
ICP vs buyer persona: what's the difference?
Quick distinction, because people mix them up:
- ICP = the company. What kind of business is a great fit? Sector, size, location, business model, stage, the events that make them need you.
- Buyer persona = the person inside that company. Their role, goals, worries and how they like to be contacted.
You need both eventually. Start with the ICP. There's no point perfecting your message to a Head of Sales at a company that will never buy.
Before you start: the one rule
Every line must be filterable. "Innovative, fast-growing companies" is not an ICP. "UK-based B2B software companies with 10-50 employees that are hiring salespeople" is. If you couldn't type it into a search or hand it to someone to build a list, rewrite it.
The 15-minute ICP process
Set a timer. Here's how to spend it.
Minutes 0-3: List your best five
Write down five customers (or, pre-revenue, five prospects who were most excited on calls). Pick the ones who:
- bought fastest,
- use the product most,
- complain least about price,
- you'd happily clone.
If you have no customers or calls yet, use the companies you most want as customers and be honest that this is a hypothesis.
Minutes 3-8: Find the patterns
For each of the five, jot down sector, headcount, location, business model, stage and what was going on when they bought. Then look across the row. What do at least three of them share? That's your core ICP. Anything only one has in common is noise, so leave it out for now.
Minutes 8-11: Write the triggers
This is the part most templates skip and the part that matters most for outbound. What happened just before they needed you? Common triggers:
- They hired for a specific role.
- They raised money.
- A new leader joined.
- They launched a new product or entered a new market.
- They hit a size where the old way stopped working.
Triggers turn a static ICP into a list of who to contact this week. (More on that in what buying signals are and how to use them.)
Minutes 11-14: Write your disqualifiers
Who looks like a fit but isn't? Too small to pay, too big to move fast, wrong tech stack, regulated in a way you can't support, or a sector where you've lost every deal. Writing these down saves more time than anything else on the page.
Minute 15: Sense-check
Read it back and ask: if I gave this to a stranger, would they build roughly the same list I would? If yes, you're done. If not, tighten the vague lines.

Review date:A worked example
Say you run a tool that helps small sales teams onboard new reps faster. A filled-in version might look like this:
- Summary: We sell to B2B software companies building their first proper sales team, usually right after they start hiring account executives.
- Firmographics: B2B SaaS; 15-150 employees; UK and Ireland; sales-led or hybrid.
- Nice-to-haves: recently raised; already uses a CRM; founder still involved in sales.
- Problem: "Every new rep takes ages to get useful, and I'm the only one who can train them."
- Triggers: posting two or more sales roles; hiring a first sales leader; new funding; a new commercial director appearing on the company record.
- Who: founder or CEO (buyer), first sales leader (champion), finance (possible blocker).
- Disqualifiers: fewer than three salespeople expected; enterprise companies with an in-house enablement team; B2C.
- Confidence: based on our first handful of customers and a set of discovery calls; review next quarter.
Notice that every line can be searched or filtered. That's the test.
Common ICP mistakes
Making it too broad
"SMBs" isn't a segment, it's most of the economy. Narrow feels scary because it seems to shrink your market. In practice it does the opposite: your messaging lands, so more of the market says yes.
Making it too clever
Twelve weighted criteria and a scoring formula is great at a 200-person company. At five people, it's procrastination. Get to a page you can use, then iterate.
Never updating it
Your first ICP is a guess. Every won deal, lost deal and churned customer is evidence. Look at it at least once a quarter, and change it when the evidence says so.
Confusing who you want with who buys
Founders often fall for prestigious logos. If your fastest, happiest customers are 20-person agencies, that's your ICP, even if you dreamed of selling to banks.
Leaving out triggers
A profile without triggers tells you who could buy. Triggers tell you who's likely to buy now. For a founder with an hour a day for outbound, that difference is everything.
Turning your ICP into a daily list
Once you have a one-page ICP, the next job is finding companies that match it and are showing a trigger right now. You can do that by hand: check job boards, funding news, X and Companies House each morning, then cross-reference against your profile. It works. It's also the first thing that slips when you're busy.
Outrun is built to take that off your plate. You enter your ICP once. If you'd rather not fill in fields, write a plain-English description ("UK B2B SaaS companies, 15-150 people, hiring their first salespeople") and AI turns it into structured fields you can tweak. Every weekday morning at 7am in your timezone, you get a digest of leads showing a fresh buying signal (from new job posts, funding and news, public posts on X and UK Companies House changes), each with a why-now line and a contact, in your inbox (or Slack/Telegram on Growth and up).

FAQ
What should an ideal customer profile include?
At minimum: industry, company size, geography, business model, the core problem you solve, the trigger events that make companies buy, who inside the company you talk to, and clear disqualifiers. Every line should be specific enough to filter a list on.
How is an ICP different from a buyer persona?
An ICP describes the type of company that's a great fit. A buyer persona describes the person inside that company, such as their role, goals and concerns. Define the ICP first, then the personas within it.
Can I define an ICP before I have customers?
Yes. Base it on your most enthusiastic prospects, the problem you know best, or the market you understand. Label it a hypothesis, then update it as soon as real deals and conversations give you evidence.
How often should I update my ICP?
Review it at least quarterly, and any time you notice a pattern in won, lost or churned deals. Early-stage companies often find their ICP shifts a lot in the first year, which is normal.
What's the difference between an ICP template for B2B and B2C?
B2B templates focus on company attributes (sector, headcount, funding stage, buying committee). B2C profiles focus on individual traits such as demographics, behaviour and preferences. This template is built for B2B.
