Product & workflow

Compared to other note-taking software that integrates LaTeX for mathematics, I have been able to add equations [much more] intuitively, with automatic formatting and none of the 'backslash' malarkey.

Founders & team

Ralph Rouhana

Founder/CEO

Hey, I'm Ralph 👋 I founded Stempad in early 2024 to help me take notes in my final year of school. After getting it to several hundred users and a few paying subscribers, I saw the potential for schools, research teams, pharmaceutical companies, tutoring companies, and more. I've previously interned at BioRender (W18), Microsoft, and 5 other companies.
