Goin is a mobile application to save money easily and take advantage of it without knowing how to invest, through Machine Learning algorithms that allow you to accumulate the user's money through small daily gestures. he three Spanish founders, David, Carlos and Gabriel, were looking for a way to optimize their own money, and decided to conduct an experiment by exchanging their debit cards and thus saving 62% during those two months of rehearsal. This is how Goin emerged, which aims to meet the needs of 100% of Millennials, of which 83% confess that they do not know how to save, making available an easy-to-use tool that enhances their finances and lifestyle. On the one hand, the Barcelona startup allows the user to add money automatically and multiply it without having previous knowledge of investment. Goin uses a simple system that first asks to know the user through questions about their habits and, in this way, they are offered automatic systems and methods of saving. Once the user adds money to the app, they can transfer part or all of it to investment, or to their bank account. Its Smart Saving technology manages to accumulate money with small, everyday gestures, such as rounding a payment.
