FAQPage Schema
How do I validate a product idea before building it?

You can validate a product idea by running through a structured Q&A that surfaces concrete demand and reveals hidden assumptions. This method guides you through context, forcing questions, and premise challenges to produce a design doc.

What questions should I ask to test startup demand and willingness to pay?

Testing startup demand involves asking focused questions about market reality and willingness to pay. By challenging premises about current solutions and target users, you expose real demand and surface critical assumptions.

Can I use structured discovery prompts for side project validation?

Structured discovery prompts work for side project validation through builder mode, which explores lightweight experiments and rapid validation. This ensures your side project follows a structured dialogue fit for non-commercial contexts.

What is the best way to document product discovery and next steps?

Documenting product discovery is best achieved by generating a design doc that captures actionable next steps. This ensures a documented outcome and creates follow-up tasks based on your validated target user and demand findings.

How do I identify hidden assumptions in my product concept?

You identify hidden assumptions by using a structured dialogue that challenges your premises and asks forcing questions. This exposes critical assumptions about your target user and demand before committing to development.
