How to Validate Any Business Idea in 7 Days
A 5-test validation sprint: landing page, 10 outreach messages, pre-sales, and kill criteria.
Day 1–2: Define the painful problem
Write one sentence: who pays, for what outcome, and why now. If you cannot name 20 specific buyers, the niche is too vague.
Day 3–4: 10 conversations
Cold email or DM 10 ideal buyers with a 3-line pitch. Aim for 3+ calls. Ask about current workaround and budget, not compliments.
Day 5–7: Pre-sell
Offer a paid pilot or deposit before building. One pre-sale beats 100 survey yeses. Kill criteria: zero calls booked after 30 outreaches means reposition.
