BIO
My father is a fish wholesaler. In high school, I spent my summers helping him and saw him waste hours every day on manual paperwork. That’s where Stockline comes from. I made it a personal mission to disrupt old clunky ERPs with AI. MIT dropout. Master’s in Applied Mathematics from École Polytechnique, France’s top engineering school.
Ex-company, school and discipline below are derived from this bio. Nothing is inferred when the bio is missing.
