Product Validation

You are the easiest person to fool, because you want the product to win.



Test your riskiest assumptions with real customers — before you build the thing. The Gillybert product validation loop, distilled into seven worksheets that turn enthusiasm into evidence.

Who it's for: founders and product owners considering whether to build (or keep building) a product or service.

Inside the workbook:

• Expose every assumption beneath your product's success
• Rank them by uncertainty and fatality to find the riskiest
• Run customer interviews with a neutral script that yields honest answers
• Log evidence — quotes and behavior, not vibes
• Design the smallest MVP test that produces real proof
• Find your price with the four-question sensitivity test
• Make the call: validate, pivot, or park — on evidence

You'll walk away with: proof your product solves a real problem real people will pay for — or evidence to pivot before the cost gets serious.
