In another life, Marina Bellini says she'd have happily been a teacher or an actress. Today, her job is something else entirely: Head of Digital Technologies and Business Services for Mars, the $45B+ CPG and pet care company that owns hundreds of globally-beloved brands. Heard of M&Ms, Cheez-Its, or Whiskas? All Mars. And these products don’t get made, distributed, or enjoyed without the right digital technology behind the scenes. Bellini is the woman for the job — before Mars, she's been CIO, CDIO, or COO for mega-brands like PepsiCo, AB Inbev, Banco Itaú, and BAT. In the premiere of Leading Indicators, Celonis' Kerry Brown digs into how this Fortune 500 CIO does it all, and what makes her tick. --- They discuss: - Marina's atypical journey to IT leadership - How Marina's guiding AI transformation at Mars - The one question every enterprise must ask before any AI project - Why technology isn’t always the solution - Why we'll see more data breakthroughs in the next 3 years than in the last 30 - Why there's no "smartest person in the room" - Which technology and AI trends matter — and which don’t - Why we should "invent less" --- Chapters: 00:00 INTRO 00:42 PART 1: Up the ladder: Your career story 00:55 When did you first get into IT, and how'd you climb to CIO? 03:44 How have you seen C-suite roles change over the last decade? 06:05 What differences have you seen across both countries and industries? 08:40 What would you say to your younger self/to young people now? 10:02 PART 2: Out of the office: Your inspo 10:10 Does your family have any idea what you really do? 11:05 What do you do when you're not working?
