Days 1–7: Problem Validation
Talk to 10 people who have the problem. Don't pitch your solution. Listen. If you can't find 10 people who care about the problem, the market doesn't exist.
Days 8–35: Build the MVP
Four focused weeks. Core loop only. Deploy on day 30. Not day 35.
Days 36–60: Find Your First Customer
Go back to the 10 people you interviewed. Show them what you built. Ask for money. If they won't pay, ask why. Iterate until someone does.
