Customers & Research

How do I define my ideal customer when I'm a domain expert who thinks everyone in my industry needs this?

A starting point

Deep industry knowledge is an edge, but it makes you assume the whole field shares your urgency, and it almost never does. Split your industry by who feels this pain daily versus occasionally, who has budget to fix it versus who just complains, and who can adopt without a committee. Your ICP is the intersection of acute pain, real budget, and fast decisions, which is usually a small slice, not the sector. Interview people outside your own bubble to check whether your certainty is expertise or blind spot, and treat your first cut as a hypothesis.

Why we picked it This is the practical step after you accept that not everyone in your industry is your customer. It walks through turning a vague 'everyone in my field' into a sharp, testable ideal customer profile, with concrete before and after examples (from 'small businesses' to 'boutique marketing agencies with under 10 employees'). For a domain expert convinced the whole market needs their product, it is a clear push to pick the narrow segment that needs it most and start there.

The Ideal Client Profile Is Your Startup's North Star (Stop Ignoring It)

From Startups.com by Ryan Rutan About 12 minute read

  • Trying to serve everyone means you resonate with no one. Specificity in who you target sharpens positioning, messaging, and conversion.
  • A good ICP is concrete: firm size, role, situation, and pain, not a broad industry label.
  • Nail the ICP first. Marketing, sales, and product all get easier once you know exactly who you are building for.
