The six forcing questions (YC office hours)

Smart-routed by stage:

• Pre-product → Q1, Q2, Q3
• Has users → Q2, Q4, Q5
• Has paying customers → Q4, Q5, Q6
• Pure infra/eng → Q2, Q4 only

Ask one at a time. Push for specificity. Wait for the answer before asking the next.

Q1: Demand reality

"What's the strongest evidence you have that someone actually wants this — not 'is interested,' not 'signed up for a waitlist,' but would be genuinely upset if it disappeared tomorrow?"
