Wandeldarlehen (lean):
- Phase 1: 3 Personen, ~60k ARR, Prototyp → Produktiv
- Phase 2: 4-5 Personen, ~200k ARR, erster Dev + Security
- Phase 3: 5-7 Personen, ~500k-1M ARR, Vertrieb + Break-Even
- Phase 4: 7-10 Personen, ~2-3M ARR, profitabel organisch

1 Mio (unchanged):
- Phase 1-4: 5→35 MA, 75k→10M ARR

Risks slide already visible for both versions (in slide order).
