## ❓ 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.
