Stewart has spent six years at Maxus, first as Asia Pacific chief executive and then as chief client officer since September 2013.
He will join Facebook as head of agency for APAC and will remain based in Singapore. "One of the organisations that is driving change in the way we all connect and spend our time online and on mobile is Facebook—so naturally I am delighted to be joining them next year,” said Stewart.
Lindsay Pattison, global CEO at Maxus, had this to say of Stewart's departure, "Neil was a very early recruit into our family and has helped to shape the great agency we are today. He grew the Asia-Pacific region at a tremendous rate, has been pivotal in our success and made many, many friends along the way."
There are currently no plans to replace Stewart's role. Pattison will work with the senior client leads within Maxus to ensure the continuation of Stewart’s work.
