Why it works today
Horizontal SaaS captured only 1-5% of economic value by acting as a passive system of record. Vertical AI captures 25-50% by actively automating cognitive work (e.g., specialized contract review). Using AI IDEs like Cursor, a solo founder can now build an MVP that previously required millions in seed funding. You only need ~194 paying users at $49/mo to generate a life-changing $10k MRR business.
Vidéo Explicative Recommandée
1. Absolute Microniche Identification
Avoid saturated generic AI wrappers. Target underserved segments (e.g., compliance monitoring for small logistics firms) where regulatory failures cost thousands.
2. Rapid Validation & Pre-selling
Before coding, build a landing page detailing the solution. If the target audience refuses to join a waitlist or pre-pay, discard the idea immediately.
3. Lean MVP Construction
Use Bubble or Cursor to build the app. Ensure underlying AI API processing costs remain strictly under 20% of your retail subscription price to maintain gross margins.
4. Workflow Embedding
Launch to the waitlist and iterate obsessively. Transition from adding generic features to embedding the software seamlessly into the user's daily reality.
