Both Samsung and Mathieu confirmed the move to Adweek.
Meanwhile, according to WSJ, Samsung Electronics America's investigation was into whether employees had violated company policies in their dealings with business partners and had resulted in several layoffs. During that time, the company had allegedly also seen the "departure of top U.S. marketing executives."
Marketing has reached out to Samsung for more comments. It remains unclear if Mathieu's departure had anything to do with the recent changes in the marketing division.
Prior to his time with Samsung, Mathieu was SVP of global marketing at Unilever. He is responsible for the development of Unilever’s global marketing strategy ‘Crafting Brands for Life’ to build brands with purpose that improve the lives of the people they serve. The strategy supports the company’s sustainable growth ambition of doubling the size of its business whilst reducing environmental impact and increasing positive social impact.
According to his LinkedIn, Mathieu also oversaw the implementation of pivotal programmes such as Project Sunlight, the first Unilever brand consumer initiative to motivate millions of people to adopt more sustainable lifestyles, and The Unilever Foundry, a platform that provides a single entry-point for innovative start-ups seeking to partner with Unilever.
