Luis Henrich-Bandis

I’m a 22-year-old solo founder of StudyPDF, used by 85,000 students to learn from their documents with AI. I’m also finishing my Master’s at RWTH Aachen.

I write here about building products solo, the strange dual life of running a company while still in school, and occasional notes on engineering and machine learning.
