In this episode of Plus Forty Nine, we talk to Federica Moreno, co-founder of Uphavin, about building a sustainable startup in Germany and the role of social responsibility in consumerism. She also shares her take on German bureaucracy and why Germany’s direct communication was a big cultural shock for her. In our culture segment, we break down the unspoken rules of public transportation etiquette, and in Ask a German, we tackle an essential question: how many beers are too many in Germany? Plus, we’ll bring you the latest news, including the impact of international students on Germany’s economy and the ongoing BER airport debate.
