PARIS — Edelman Europe and CIS head of digital Grégoire Assémat-Tessandier is leaving the firm, prompting the firm to search for a replacement who can drive digital growth in the region.

Assémat-Tessandier steps down after joining Edelman two years ago. Edelman Europe/CIS CEO Michael Stewart said that he is relocating to New York with his family, where he will join digital agency Huge.

"We are grateful to Grégoire for his contributions and wish him every success for the future," said Stewart. "Europe is a key priority this fiscal for digital and we are aggressively looking for a number of people who can drive that growth."

While Edelman's digital practice across Europe and CIS numbers more than 200 people, it attributed for 11% of revenues in 2015, a proportion that Stewart believes must increase. Edelman's revenue in the region totalled around $160m last year.

Assémat-Tessandier joined Edelman from TBWA, where he led the network's DAN Paris digital outfit as managing director. The Frenchman was global head of digital at Bacardi Global Brands prior to his four-year stint at TBWA in Paris.
