How AI Is Used

Image models are fine-tuned on each user's photos to generate new portraits and photoshoots.

Step-by-Step Process

Step 01Build on earlier experiments

Levels previously launched AI avatar and interior design products.

Step 02Keep the stack simple

A single large PHP file instead of a complex architecture.

Step 03Share numbers publicly

Public revenue updates double as marketing.

Customer Acquisition & Distribution

Levels' large audience on X and his newsletter.

Limitations, Risks & Failure Modes

What may not apply to you, and what could go wrong:

  • A very large personal audience is hard to replicate
  • AI photo generation is now a crowded market
  • Self-reported figures

Key Takeaways

  • Revenue and profit are both stated, which few founders do
  • Simple technology can support a large business
  • Audience is a major advantage when launching AI products
