“Arne and Matthias [co-founders and CEO, Tuta] encourage us to speak up about mistakes openly and honestly so that we can learn from these and grow as a team. Arne and Matthias are also deeply rooted in Hannover, strictly adhere to German laws, including working times, and they wouldn't even think about moving the company elsewhere just for different working laws or things like that.”
