Martello runs the fastest growing division of the world’s largest food company Nestlé. And that division, which spans Asia, Oceania and Sub-Saharan Africa—with 100,000 employees in 93 countries—has performed solidly, recording 4.7% organic growth (more than double Nestlé’s rate) in 2017. (Stats are similar for the first half of 2018). Martello joined the Swiss milk and candy giant from [f500link]Walmart[/f500link] in 2011 to become its CFO and took on her current role in 2015. She currently oversees $22 billion in revenue and has increasingly assumed a wide range of responsibilities: This year she joined the board of Nestlé’s Blue Bottle Coffee, and she’s working to build out the company’s partnership with [f500link]Starbucks[/f500link]. Martello also has board seats on two of the world’s most buzzed-about companies—Alibaba and Uber—and is reported to be a possible contender for the top job at consumer good rival Unilever when current CEO Paul Polman retires.
