When testing for product-market fit, it's essential to ask customers deep, probing questions to truly understand their problems and needs.

To effectively interview potential customers, ask open-ended follow-up questions that encourage them to share their problems and experiences.

When discussing your product with potential users, ask them to identify reasons they might not buy it, which can reveal critical pain points.

Asking specific questions about how potential customers currently handle a problem can reveal valuable insights into their needs and challenges, and understanding user motivation is critical for solving their problems effectively.

When developing a product, it's crucial to talk to users who are already using your service to understand their detailed needs and pain points.

Founders should conduct their own sales calls to qualify customers and understand their pain points better.

To validate your product, focus on gaining insights from potential customers about their pain points and the value your solution provides.

It's crucial to listen to customer feedback rather than just describing your product; resist the urge to showcase your product immediately and ask questions instead.

Conduct customer interviews to understand their motivations and pain points; aim for five to ten interviews for qualitative insights.
