Facteurs de risque

• High margin volatility: profit swings from -$1,448 to $3,232/month
• Very long and uncertain break-even (up to 999 months) suggests demand/cost mismatch
• Revenue sensitivity in a crowded local environment (500 nearby competitors)
• Brick-and-mortar fixed costs could amplify losses during slower months
• Low certainty on hitting consistent daily throughput needed to stabilize monthly profit

Plan d’exécution

1. Validate local demand with a 2-4 week pre-launch test (limited menu, pop-up or street sampling) in Rennes
2. Optimize the core menu for high gross margin and speed (signature items, fewer SKUs, tighten batch prep)
3. Build a pricing and promo strategy to smooth week-to-week traffic (weekday lunch bundles, loyalty stamps, events)
4. Reduce fixed cost risk by renegotiating rent/lease terms or adding flexible hours and staffing models
5. Target repeat customers with a CRM (loyalty app/cards, email/SMS, seasonal offers) and measure CAC vs. contribution margin
6. Launch partnerships nearby (offices, coworking, gyms, local events) to secure predictable weekday volume
