Subject: Sergiu Chiriac (AI Directories)Paid submission service for startups and AI products to 100+ directories

Case Overview & Background
Sergiu Chiriac, a software engineer with ten years of experience, launched several AI startups from 2023. Submitting each one to directories by hand was slow, so he built an internal tool that became AI Directories. He says it has helped 900+ founders and made $9.5K of his record $15.7K month.

Limitations, Risks & Failure Modes
What may not apply to you, and what could go wrong:
- The figure is self-reported and was not independently checked
- AI is the market rather than the product
- Directory value can fade if search engines change
Key Takeaways
- Tools built for your own launches can become products
- Selling to other AI founders is a niche in itself
