Simon Sasse is a computer scientist, podcaster and musician. As the drummer of "Brass Riot" he has been playing concerts for several years, preferably at festivals or climate demos. He also has his own fact-checking podcast "podfaktisch" with Jannik Werner, which regularly reports on current fake news in an entertaining way. In this context, the fake news quiz app "QuellenReiter:in" was also created, with which one learns to recognize disinformation in multiplayer. The app was funded by the German Federal Ministry of Education and Research and the Prototype Fund.
