What is the difference between an ICP and a buyer persona?

An ICP defines the best-fit segment for your business. A buyer persona describes the individual decision-maker within that segment. Define the ICP first, then build personas inside it.

How do you validate an ICP?

Look at behavioural and commercial outcomes — conversion rate by segment, sales cycle length, retention, customer lifetime value, revenue contribution. Consistent outperformance is your evidence.

Can an ICP change over time?

Yes. Review it when your product, pricing, market conditions, or customer behaviour shift.

Is an ICP only useful for SaaS companies?

No — this exact framework works with craft brands, campsites, log cabin builders and service businesses, not just software.

How often should you update an ICP?

At least quarterly in a fast-moving market, and always after a repositioning, a pricing change, or a real shift in who's actually buying.
