YOKUU 4A

Joris Jansen

Co-founder

Joris Jansen is a bio-engineer with a passion for the fascinating world of bacteria. His fascination began during his master’s thesis, where he studied the microbial composition of indoor environments. There, he discovered an alarming link between the rise in allergies and our obsession with sterilising everything around us.

As a creative thinker with a nose for innovation, Joris is always looking for ways to improve — or disrupt — existing systems. At YOKUU, he is the brain behind sales strategy, product development, and production. Always curious, always ready to challenge the status quo — and always with a smile 😍.
