We never expected to set up a tampon company

And now we can’t imagine doing anything else.

Mariah & Wendelien have been friends for over 16 years. They never expected to set up a tampon company but they found each other and the motivation to do so in Yoni’s story. They founded Yoni together in 2014 and beginning of 2015 they started sales.

Mariah Mansvelt Beck


Mariah is a storyteller pur sang. Whether giving a (TED) talk or creating creative Yoni campaigns. She’s all about breaking the taboo and sharing the story, inspiring women to make their own choices. 

Wendelien Hebly


Wendelien loves the challenge of a good puzzle whether it be with data, details or stories. Let her put together a business case, write a winning strategy or create a great presentation. Her focus always puts planet and people first.
