❓ FAQ

Q: Do I need to read all documents? A: No. Start with the CRITICAL section. Read others as needed for your role.

Q: Can I skip Phase 0 (Validation)? A: No. DO NOT SKIP. This saves you from building something nobody wants.

Q: Should I raise money before or after Phase 0? A: Start fundraising in Week 3-4 (while doing final interviews). Close by Week 7.

Q: How much money do I really need? A: €350-450K for MVP. €600-800K with runway is safer.

Q: What if validation shows NO-GO? A: Pivot to Pain Point #2 or #3. Same interview process, different solution.

Q: Can I build all 5 solutions? A: No. That's why we wrote REALISTIC_VS_OPTIMISTIC.md. Read it.
