Austrian startup Gropyus, valued at €400 million, is taking legal action against its former supervisory board chairman, Stefan Fritsch. The investigation also centers around travel undertaken by Fritsch with Harald Mahrer, who previously served as the head of the Austrian Federal Economic Chamber (WKÖ). Specifically, authorities are scrutinizing private jet trips taken by the two former executives. The nature of these trips and their potential connection to the ongoing case involving Gropyus are currently under investigation. Details surrounding the purpose and funding of the travel are being sought by investigators. This development adds another layer of complexity to the situation surrounding the rapidly growing construction-tech company. The inquiry focuses on potential irregularities related to the use of company resources and adherence to corporate governance standards.
