“The next chapter is an opportunity to apply many of those lessons at global scale, at a moment when AI, platforms, creativity, data and culture are rapidly reshaping how brands grow and communicate. The industry is entering a period of profound change and I’m excited to help shape what comes next within a business that is truly operating at the forefront of that transformation,” the post read.
