Both Dingwitz and Martens will join the provider’s management board, sitting alongside chief executive Helmut Becker and chief financial officer Jonas Mattsson.
Dingwitz move into his new role after heading up technology operations, security and engineering at Zeal for the past five years. He will now assume responsibility for all segments of technology and IT strategy at the provider.
Prior to this he was vice president of technology at online shopping business Rue La La, had a spell as chief technology officer at ONE Media Corp and served in a number of senior engineering roles at CNN.
Martens has been part of the Zeal group for more than seven years, having responsibility for operational business in management positions such as managing director and product officer.
Before joining Zeal, Martens was responsible for corporate development at New Work and was the founder and managing director of online real-estate marketplace loftville.
As COO, he will oversee product management, marketing, brand management and brand strategy.
“As an e-commerce company, it is extremely important for Zeal to meet a high technological standard and to be customer-focussed in our operations,” Zeal chairman Peter Steiner said. “We are proud that two experienced managers from our own ranks will support our plans to drive profitable growth in the years to come.
“In addition, the creation of these management board responsibilities demonstrates the appreciation of the success already achieved by Paul Dingwitz and Sönke Martens and underlines the importance of these roles for the future success of the Zeal Group.”
The double appointment comes after Zeal this week made an offer to purchase the remaining shares in Lotto24 and take full ownership of the online lottery broker it spun off in 2012.
Zeal already owns 93% of the total shares in Lotto24 and the agreement would see Lotto24 delist its remaining shares from the Frankfurt Stock Exchange in order to allow Zeal to acquire them.
