rubarb helps consumers have more money at the end of each month by reducing large bills, saving automatically and investing these savings with sustainable ETFs. With our easy to use app, currently available in the German app stores for iOS and Android, users can define their individual dreams such as the next vacation, owning a home or even retirement. Users can easily save money through round-ups, savings plans or one time pay-ins for each of these dreams. Their savings are automatically invested into globally diversified sustainable ETF portfolios. rubarb also helps users save up to 500€ annually per large bill by automatically changing providers - e.g. of energy contracts - to the best offer each year again and again.
