Programmatic platform DataXu has made three new senior appointments across the US and Europe.

Jan Heumueller, former vice president of sales, Europe, will succeed Sacha Berlik as of 31 March, running DataXu’s European operation based in Cologne.

Berlik is said to be taking some time off after 20 years in the media industry. As his replacement, Heumueller will focus on expanding DataXu’s business and strategic efforts across the European market.

Chris Le May, former director of sales for the UK, assumes the position of country manager, UK and Nordics. Meanwhile, Martin Brown steps into the role of vice president, sales US East from his previous position as DataXu’s vice president of UK and Nordics. Brown has relocated to DataXu’s New York office.

Mike Baker, DataXu chief executive said: “The appointments we have announced today demonstrate the excellence and strength of our organisation and will lead DataXu into our next phase of truly global development.

“Our sustained success, deep client relationships and ongoing investment in the best talent will result in expanded global operations throughout 2015 and beyond,” he added.

In his new role as DataXu’s country manager for the UK and Nordics, Le May will lead the growing London team, using his experience within the digital sector to bring DataXu’s programmatic marketing solution to brands and agencies.

Le May said: “More businesses are realising how hugely important programmatic marketing is across all levels, so helping them get even closer to their own data and make the most of it through our platform is a key priority for us in 2015.”

Brown, a DataXu employee since 2011, said: “In the UK, we’ve made huge strides working extensively with clients across both brands and agencies to help them implement new and effective programmatic marketing strategies. Now, I’m looking forward to leading the team in New York and further prove the value of programmatic marketing to advertisers.”
