How to Identify Your Ideal Customer Profile (ICP)

Why Your Ideal Customer Profile (ICP) is the Foundation of Your Success

If you don’t know exactly who your ideal customer is, your SaaS business is already on shaky ground. Too many SaaS companies rush into marketing and sales without truly understanding their ICP, leading to wasted budgets, poor conversion rates, and stagnation.

Your ICP is not just about who could buy your product – it’s about who is most likely to buy, stay, and generate long-term revenue. Without this clarity, your business is simply guessing, and in SaaS, guessing is expensive.

So, how do you identify your ICP with confidence? Let’s break it down step by step.

1. Analyse Your Best Existing Customers

The easiest way to identify your ICP is to look at the data you already have. Your best customers – the ones who spend the most, stay the longest, and require the least effort to convert – are the key to unlocking your ICP.

Action Steps:

• Export a list of all your current customers.
• If possible, include past customers who were profitable before they churned.
• Create a spreadsheet with columns for key attributes, such as:
  • Industry
  • Location
  • Company size (headcount and revenue)
  • Sales cycle length (how quickly they converted)
  • Customer Lifetime Value (CLV)
  • Churn rate
• Identify trends: Which customers have the highest CLV and lowest churn? Are they concentrated in specific industries or company sizes?

By the end of this exercise, you should start to see patterns emerge. For example, you might find that your best customers are UK-based construction companies with 50–100 employees.

2. Speak Directly to Your Best Customers

Data will tell you who your best customers are, but conversations will tell you why they chose you in the first place.

Action Steps:

• Select 5–10 of your best customers and request short interviews.
• Ask them:
  • What problem were you trying to solve when you found us?
  • What alternatives did you consider?
  • What made you choose us over competitors?
  • What do you love most about our product/service?
  • What nearly stopped you from buying?
• Document their responses and look for common themes.

If multiple customers say they chose you because of your fast onboarding or your simple UI, that’s a messaging point you should amplify in your marketing.

3. Test and Validate with Small Ad Campaigns

You don’t need to spend thousands to test your ICP. A small ad budget can quickly confirm whether your assumptions are correct.

Action Steps:

• Create a couple of LinkedIn or Meta ad campaigns targeting different audience segments based on your findings.
• Test different messages to see what resonates most.
• Monitor key metrics like click-through rate (CTR) and conversion rate.

If one audience converts significantly better than another, you’ve got solid evidence that they are part of your true ICP.

4. Study Who Didn’t Convert (and Why)

Equally important to knowing who your best customers are is understanding who isn’t a good fit. This can help you avoid wasting time and resources on the wrong prospects.

Action Steps:

• Look at demo requests or free trials that never converted.
• Analyse common objections during sales calls.
• Identify customers who churned quickly and figure out why.

You may discover that enterprise clients with 500+ employees tend to churn fast because they require features your product doesn’t have. If so, stop wasting marketing spend on them.

5. Adjust Your Messaging, Website, and Sales Process

Now that you have a clear ICP, you need to reflect it everywhere in your business.

Action Steps:

• Update your website copy to highlight the pain points and benefits that matter most to your ICP.
• Create case studies featuring your best-fit customers.
• Train your sales team to refine their pitch and objection handling based on real ICP insights.

For example, if your best customers are startups looking to reduce admin time, your homepage headline should speak directly to that pain point: “Automate Your Admin and Scale Faster” rather than a vague “The #1 SaaS for Business Growth.”

Final Thoughts

Finding your ICP is not a one-time exercise – it’s an ongoing process. Markets change, your product evolves, and new customer segments may emerge. The key is to continually refine your ICP using real data, real conversations, and real-world testing.

If you’re serious about scaling your SaaS business, getting this right is non-negotiable. Because when you know exactly who to target, your marketing becomes sharper, your sales process smoother, and your growth unstoppable.
