Welcome to Before They Change The World, where we explore the minds and ideas of inspiring individuals working on impactful projects, before they change the world.
We're David and Junwoo and are based in Zurich, a tech hub where countless spinoffs and startups thrive. After being exposed to this environment, our curiosity drove us to start this podcast and uncover the minds behind these projects.

Every episode will be a casual 1 on 1 conversation about routines, struggles, and hobbies of inspiring guests as well as their research or entrepreneurial endeavors before they hit the world stage.

We will be interviewing people developing carbon capture technologies, electric airplanes, Virtual Reality Gyms, River Cleaning Robots, AI-powered music tools and so many more!
