About Prestatech

At Prestatech, we're redefining the financial world by fostering innovation and challenging the traditional banking system. Our culture is diverse, dynamic, and forward-thinking. From our offices in Berlin and Milan, we create cutting-edge API technologies in an inclusive environment where everyone can contribute their best work.

Founded in 2021 by Christian Nothacker, Luca Terragni, and Lorenzo Giusti, Prestatech combines document automation and proprietary technology to help financial institutions and B2B companies make quick, reliable, and inclusive credit decisions for SMEs and consumers.

When most people think of getting a loan or mortgage, they picture a slow and tedious process. Our mission is to simplify that through technology.

We're a young and fast-growing company—but this is our second venture. Before Prestatech, we founded and exited Prestacap, a lending platform for SMEs active in Italy and Germany.

We're passionate about data and technology, never satisfied with the status quo, and believe that teamwork is key to achieving ambitious goals together.

To date, we have raised €8 million, which is helping us bring more innovative solutions to market, expand operations in Italy, and launch in the UK, Germany, and the US..
