Teen Built 50K-User Platform With Just 10 Lines of Code

A 15-year-old just built a financial research platform with 50k monthly users by writing only ~10 lines of code himself, according to the WSJ.

His approach was pretty straightforward - he used Claude as the primary developer to generate all the software, then brought in ChatGPT and Gemini for specific supporting tasks. Instead of coding, he focused on designing the system, iterating on what worked, and getting people to actually use it.

The results were solid enough that a public company republished one of his AI-generated research reports, thinking it came from a professional firm.

The shift: Time spent on implementation (coding) dropped to near-zero, while time on product design and distribution went way up. No team needed, no employees, just prompting skills and knowing which model handles what best.
