Facteurs de risque

• CAC inflation risk: revenue variability ($21k–$36k) could widen break-even beyond the 3–7 month window
• Churn risk: SaaS retention shortfalls can compress monthly profit ($7.2k–$17.7k) and delay profitability
• Pricing/packaging risk: if ARPA underperforms, profit margins may not sustain the $7,200 minimum profit range
• Market validation risk: 0 nearby competitors could indicate limited demand/keyword opportunity despite the high score

Plan d’exécution

1. Define a narrow ICP and build 3–5 high-intent landing pages optimized for SEO and conversion
2. Instrument analytics (activation, churn, cohort retention) and run weekly funnel reporting to track leading indicators
3. Launch lead-gen with content + outreach and target a monthly revenue path toward the $36,000 upper range
4. Implement lifecycle email/onboarding plus in-product onboarding to protect retention and maintain $7,200+ monthly profit floors
5. Set pricing tests (tiering/annual plans) to improve ARPA and shorten the path to 3–7 month break-even
6. Create a 90-day cost and runway model to ensure spend stays compatible with rapid break-even
