ICP Definition and Segmentation

By Exit Five (B2B Marketing)

Define and target your ideal customer profile with clarity and precision.

A/B Test Setup

• Helps you write a clear hypothesis for what you're testing and why
• Calculates how much traffic and time you need for statistically valid results
• Guides you in choosing primary, secondary, and guardrail metrics to track

• Analyzes results and tells you whether the difference is real or just noise

ICP Definition and Segmentation

• Shows you how to validate your ICP using customer data, NPS scores, and win/loss patterns
