Natixis Investment Managers lifted out a team of senior global thematic portfolio managers from Pictet Asset Management, a spokeswoman said.
Arnaud Bisschop, Frédéric Dupraz and Nolan Hoffmeyer all joined as fund managers. All three positions are new.
Natixis plans to hire additional two fund managers in early 2019 as it launches a range of thematic strategies, including water, safety, artificial intelligence and robotics, the spokeswoman said.
At Pictet, the three developed thematic funds now with €21 billion ($23.8 billion) invested, Natixis said in a news release.
A Pictet spokesman could not be reached for comment.
"These managers have been pioneers in global thematic investing. Their entrepreneurial mindset and highly active investment approach fit perfectly with our philosophy. The combination of a proven track record and strong expertise will make a substantial contribution to our global equity range," Jean Raby, CEO of Natixis said in the release.
Natixis has €861 billion under management.
