Facteurs de risque

• Profit volatility: monthly profit ranges from -$1394 to $1396
• Long and uncertain break-even: 26 to 999 months
• Revenue concentration risk: $6300–$10800 monthly may not cover fixed costs year-round
• High local competitive density: 500 nearby competitors could cap pricing and footfall

Plan d’exécution

1. Model seasonal cash flow for Rennes and size staffing/inventory around peak vs off-peak months
2. Differentiate the menu with local ingredients, signature flavors, and seasonal limited drops to defend margins
3. Increase average order value via bundles (gaufres/wraps), upsells (toppings, premium scoops), and loyalty programs
4. Run targeted local marketing (Google Maps, Instagram Reels, nearby office/student promos) to drive repeat visits
5. Tighten unit economics: track gross margin per SKU and renegotiate suppliers/portioning to reduce waste
6. Validate demand quickly with pop-up tastings and pre-order bundles ahead of full seasonal ramp-up
