Personas and segmentation

Idea & Validation · 25 min

Customer personas are semi-fictional representations of your ideal customers based on real data from your interviews and market research. They go beyond demographics to capture motivations, behaviors, pain points, and decision-making processes.

A persona without data is just a guess. Build personas from REAL interview data, not assumptions.

For B2B products (like a medical device or enterprise software), you typically need both a User Persona (the person who uses the product daily) and a Buyer Persona (the person who signs the purchase order). These are often different people with different motivations.

B2B Medical Device Personas

User Persona: Dr. Maria Rossi, 42, radiologist at a public hospital. Does 15 ultrasound exams/day, frustrated by manual measurements taking 30+ minutes each. Wants better accuracy and faster results. Buyer Persona: Dott. Bianchi, 55, Head of Medical Equipment Procurement. Cares about ROI, CE marking compliance, and budget approval cycles (annual, Q1).

Key Takeaways

  • Personas must be based on real data, not assumptions.
  • B2B needs both User Personas and Buyer Personas.
  • Focus on behaviors and motivations, not just demographics.
  • Update personas continuously as you learn more.
