Define your ICP by picking at least three specific attributes from nine categories such as company size, job title, pain point, tech stack, and geography. Aim for a segment narrow enough that you could realistically capture 30-50% market share within two years.

An ICP should be almost comically narrow, with at least three narrowing characteristics. It must be a single market segment where the value of solving the problem and the method of reaching customers are roughly uniform across the group.

Cold outreach response rates provide the cleanest ICP validation because they lack the social bias of warm introductions from investors or friends. Track conversion rate jumps, prospect enthusiasm, urgency to buy, and physical recognition of the pain point as confirmation signals.

Default to SMBs because very small businesses have high failure rates that create churn unrelated to product quality. Choose based on which segment feels the pain most acutely and where early adopters most likely to try an unproven product are concentrated.

Expand only when two conditions are met: your current narrow ICP shows strong customer love through retention and satisfaction, and you have enough engineering bandwidth to serve a new segment without degrading the experience of your existing audience.

Common mistakes include chasing any paying customer, using vague personas instead of market segments, relying on warm introductions for validation, and expanding to adjacent segments before dominating the first one. Each dilutes focus and produces misleading product-market fit signals.
