Co-Founder, Yoni

Mariah Mansvelt Beck obtained her MPhil at the University of Cambridge and spent seven years working for Médecins Sans Frontières (MSF). In 2011, a doctor advised Mariah to start using organic tampons and pads. This was the first time she’d ever stopped to think about her choices in these products.

Together with friend and co-founder Wendelien Hebly they found out not only are
many tampons and pads made from synthetic materials and may contain plastics and perfume but there aren’t specific rules or legal requirements when it comes to listing the ingredients on the packaging of these products.

That’s why in 2014, Mariah and Wendelien founded Yoni, a brand of organic cotton
tampons, pads and panty liners. Their mission is to ensure every women can know
what her most intimate products are made from.

“We believe every woman should know what she’s putting between her legs. So let’s break the taboo, ditch the shame and start talking about periods properly”
