With our AI-based guitar learning app Fretello, we empower people to express themselves through music. This experience can look different for every user as our learning content is customizable and adapted to the experience level. Our app not only allows our users to learn, practice, and play the guitar, Fretello provides real-time feedback and enables our users to follow a learn path, choose customizable practice sessions, or learn how to play their favorite songs to perform them in front of their friends and family or even on a big stage. Founded in 2016 by Florian Lettner and Wolfgang Damm, we have ever since grown into a warm-hearted and passionate bunch of 25+ people. Not only do we strive for simplicity and iterative improvements when it comes to our app but also in the way we are working together. Our team collaborates remotely from all corners of the world or on-site in our office facilities in Linz to offer the best possible music learning experience to our users. In addition to being passionate about our product, we Fretellians value transparency, flexibility, curiosity, ownership, and foster an appreciative team environment where we support and push each other.
