Avoid Waste

We make it easy for everyone to make the last mile of their food more sustainable. We develop a digital deposit system with sustainable boxes for food to go and package-less shopping. Waste-free and convenient at once.




The app Pfandgeben offers a platform for donating bottles anonymously or in person to people who collect returnable bottles. With every donation a person in need is directly supported and the donators saves time not having to return the bottles.



Salty Electric

Salty Electric wants to revive: brains, people, clubs! The eponymously idea behind Salty Electric is a drink made of water, lemon, ice and salt. With this simple recipe people shall party longer, healthier and with more awareness so that clubs and festivals generate benefits and revenue.
