In Peter Thiel's book, Zero to One, he outlines 7 questions that every startup must answer before it can be confident in its potential for future revenues and growth.

1. The Engineering question: "Can you create breakthrough technology instead of incremental improvements?"
2. The Timing question: "Is now the right time to start your particular business?"
3. The Monopoly question: "Are you starting with a big share of a small market?"
4. The People question: "Do you have the right team?"
5. The Distribution question: "Do you have a way to not just create but deliver your product?"
6. The Durability question: "Will your market position be defensible 10 and 20 years into the future?"
7. The Secret question: "Have you identified a unique opportunity that others don't see?"
