Rainer Stiller, newly appointed CMO of DG Matrix
Stiller brings more than 25 years of progressive marketing and commercial leadership spanning the critical infrastructure and energy technology sectors. He began his career learning the marketing craft at BMW's corporate headquarters in Munich, managing key customer events and product placement programs before joining APC (American Power Conversion), where he rose from regional marketing manager to Director of Worldwide Marketing Communications, driving brand awareness to record levels across global markets. Following APC's acquisition by Schneider Electric, Stiller advanced to Senior Vice President of Global Field and Portfolio Marketing, where he launched global brand and demand generation campaigns resulting in multi-billion dollar pipeline contributions through newly deployed commercial automation systems.
Most recently, as Chief Marketing Officer of Vertiv (NYSE:VRT), a $100 billion global provider of critical digital infrastructure, Stiller oversaw the transformation of the company's marketing function. He led the brand transformation from a perceived industrial company to the undisputed leader in AI infrastructure.
During his tenure at Vertiv, Stiller was recognized as a "CMO to Watch 2024" and received the PR News "2023 People of the Year — Chief Communications Officer" award, reflecting his impact on brand equity development and integrated marketing communications at the global enterprise level.
At DG Matrix, Stiller will oversee customer experience, brand equity development, demand generation, and global alliance marketing as the company enters its next phase of commercial growth. His experience building high-performance marketing organizations across the Americas, Europe, and Asia will be instrumental as DG Matrix expands its global footprint.
"Rainer is exactly the leader we need as DG Matrix transitions from technology breakthrough to global market scale," said Haroon Inam, CEO of DG Matrix. "His track record of building world-class demand generation engines, transforming customer experiences, and driving commercial growth at companies like Vertiv and Schneider Electric is unmatched. As we accelerate deployments of our Interport platform across AI data centers and electrification projects worldwide, Rainer's expertise in brand development and go-to-market strategy will be a powerful catalyst for our growth."
"DG Matrix is at the forefront of solving one of the most critical infrastructure challenges of our time," said Rainer Stiller. "The opportunity to shape the global marketing and go-to-market strategy for a company that has commercialized the world's first multi-port solid-state transformer is truly compelling. I'm excited to join this talented team and help accelerate our reach into new markets and customer segments around the world."
Throughout his career, Stiller has transformed companies into enterprise-scale global brands, led teams of over 1,200 professionals across more than 60 countries, and built channel partner programs that expanded from 250 to 4,000 resellers in a single year. His expertise spans digital transformation, demand generation, customer and partner experience, strategic alliances, and global brand development across B2B, B2C, and B2B2C go-to-market models.
