AI is accelerating change and attention has never been harder to earn. For marketing leaders, the mandate is clear: build a brand that moves at digital speed without sacrificing clarity, consistency or credibility. Hexagon CMO Madlen Nicolaus shares a candid case study of leading a digital-first brand transformation inside one of the world's most complex technology businesses. Brand equity research found Hexagon was deeply trusted yet almost invisible: only 8% could name the company unprompted, despite a Net Promoter Score of +56 among those who knew it. Madlen takes CMOs inside the end-to-end rebuild: a simplified narrative, a refreshed identity, a website built from the ground up, and the AI-powered systems that let a small team scale content and governance without losing brand integrity. She shares what moved the numbers, including a 71% lift in brand perception and a 36% rise in global share of voice, and the leadership lessons for anyone driving transformation in a complex, matrixed, global organisation.
