BUILD THE SMALLEST PROOF - The 7-Day Founder Validation Sprint

Founders often build too much before learning enough. BUILD THE SMALLEST PROOF is a seven-day validation sprint for testing the uncertainty that matters most before committing more time, money or code. Identify the riskiest assumption, choose the cheapest credible test, define success and failure evidence before you begin, and put something real in front of users or buyers. The sprint includes test briefs, interview structures, evidence logs and a final Advance, Iterate, Kill or Park decision. The aim is not to prove you were right. It is to gather evidence strong enough to improve the next decision.
