Key Questions Answered

• •Vibe Coding Market Size: Software requiring implementers will disappear within a decade as custom-built applications become easier than buying off-the-shelf SaaS. Small businesses need simpler, customized tools without feature bloat, not generic enterprise solutions with unnecessary complexity and vendor lock-in.
• •Margin Economics Defense: Model costs will approach zero as open source models improve and intelligent routing directs simple requests to cheaper models. Base44 already shifts millions in spend overnight between providers by changing one code string based on which model performs best for specific tasks.
• •Defensibility Through Vertical Integration: The moat comes from building complete infrastructure layers including databases, user management, integrations, and scheduled tasks. Competitors using third-party services like Supabase face difficult migration paths, while vertically integrated platforms can fine-tune proprietary models on billions of code lines for high-margin operations.
• •Competitive Landscape Reality: Google poses the greatest threat due to compute resources, cloud infrastructure, and potential Gemini dominance. Cursor, Replit, and Lovable compete in different segments. The market supports multiple winners as the category becomes largest in software, with 95-100% of code AI-generated within two years.
• •Revenue Growth Expectations: Zero to ten million in annual recurring revenue within the first year defines exciting SaaS growth in the AI era. Investors should prioritize vertically integrated businesses over prompt-wrapper applications vulnerable to commoditization by model providers building similar features into core products.
