Risk Factors

• Churn risk that could delay the 3 to 7 month break-even window
• Revenue-range volatility ($21,000–$36,000) indicating possible pipeline sensitivity
• Margin compression risk if costs rise faster than profit range ($7,200–$17,700)
• Over-reliance on a narrow customer acquisition channel in a competitor-sparse market
• Product-market mismatch risk if ARPU assumptions don’t hold during scaling

Execution Plan

1. Define and validate a narrow ICP and clear value proposition with measurable outcomes
2. Implement a growth system: SEO + content + lead magnets + conversion-focused landing pages
3. Set up pricing experiments and track LTV:CAC, churn, and payback to protect the 3–7 month target
4. Automate onboarding and retention loops (email sequences, in-app guidance, success check-ins)
5. Build an instrumentation dashboard for acquisition, activation, retention, and revenue by cohort
6. Scale only after hitting consistent cohort retention targets and stable monthly revenue/profit trends
