Welcome to Dieau.


We are an innovative young company that has set itself the goal of declaring war on plastic pollution. We sell high-quality drinking bottles made of borosilicate glass, probably the most stable glass currently available for drinking bottles. Our bottles are double-walled and thus function as thermos bottles. They can also be personalised. You can find more information in our Shop.


What do we do.


What do we do? We are seven motivated students who founded DIEAU company in summer 2020 as part of the YES company programmes. In addition to successfully building our company, one of our goals is to be one of the best teams in Switzerland in the YES competition for the best young companies in 2020/21. Would you like to learn more? You can find more information about our team here. You can reach us personally via the contact.

If you want to earn money, you have to spend money.


This economic principle also applies to a start-up company. Because we as students cannot finance the entire start-up capital ourselves, we looked for investors. Thanks to a total of 41 backers, we were able to generate 3000.-CHF in start-up capital in just one month.
