Free guide: How to validate your startup idea

Evidence instead of opinions

Friends liking your idea tells you very little. This guide shows you which evidence counts, how a 20-minute problem interview runs and how to measure willingness to pay before a product exists. Plus a 30-day plan you can start on Monday.

What you will learn in this guide

• Which evidence counts and which you can safely ignore
• A 20-minute problem interview script you can use today
• Where AI cuts weeks out of your validation work and where it runs out
• Why synthetic test users cannot replace real conversations, with the research behind it
• How to measure willingness to pay before a product exists
• What product-market fit looks like and what it does not

Who this is for

• Founders with an idea who want evidence before committing money and months.
• Teams who already have a landing page and cannot tell whether the signups mean anything.
• No prior knowledge required.
