She replaces Joanna Shields, who left Facebook’s top European job in January to lead the government’s investment group for technology startups, The Tech City Investment Organisation.
When she starts her new role in July, Mendelsohn will be responsible for growing Facebook’s advertising revenue and improving relationships with brands across Europe, Central and Eastern Europe, Middle East, Africa and Russia. She will report to Carolyn Everson, Facebook’s vice president of global marketing solutions.
Everson says: “[Mendelsohn] brings outstanding leadership and passion for what Facebook can do to become an indispensable partner for our clients and agencies throughout the region. It’s testament to Facebook’s innovative role in business and advertising that we’re able to welcome a leader with such great experience.”
Facebook generated $423m in revenue from Europe in the three months to 31 March, $367m of which came from advertising, according to its latest quarterly results presentation. Average revenue per user in the region was $1.60.
Mendelsohn has served as Karmarama executive chairman for five years, working with clients such as the BBC, Costa, Honda and B&Q. She will step down from the role when she joins Facebook.
She is also a former IPA president and currently chairs the Creative Industries Council.
