## The 'Thin Wrapper' Vulnerability
Software investors expect a SaaS company to have 90% gross margins. In traditional SaaS, clicking a button costs the company $0.00001 in AWS database queries. In Generative AI SaaS, clicking "Rewrite this Document" physically costs the company $0.08 in OpenAI API tokens.
### FAQ
**Q: Why do AI startups secretly hate their most active "power users"?**
A: Fixed Pricing vs Variable Costs. If you charge a user $20/month for "Unlimited" access to your AI Copywriter, you have created a fatal economic trap. Your power users will use your tool to generate 80 articles a day. If those 80 articles cost you $1.50 in daily API tokens, that user costs you $45 a month to service. You are mathematically losing $25 a month on your best customer. High engagement literally bankrupts thin-wrapper AI companies.
