Birgit Haderer will be leaving Zalando, the German-based e-tailer. In her position as chief financial officer, Haderer was closely involved in Zalando’s expansion. Previously working for Goldman Sachs, she set up and eventually led Zalando’s financial department. In 2014, she managed Zalando’s IPO, which, at a value of $668 million, was the biggest initial public offering for a German tech company since Telekom’s in 2000. Haderer will have a similar function at Personio, a Munich-based software company.
