DG Matrix Taps Vertiv Veteran to Power its AI Infrastructure Gambit

MORRISVILLE, N.C. – March 12, 2026 – In a move signaling an aggressive push for market dominance, solid-state transformer pioneer DG Matrix has appointed Rainer Stiller, the marketing architect behind Vertiv’s ascent in the AI infrastructure space, as its new Chief Marketing Officer. The appointment comes at a critical juncture for the tech industry, as the voracious energy appetite of artificial intelligence threatens to outpace the development of global power grids, creating a high-stakes race for innovative solutions.

Stiller, a 25-year veteran of the critical infrastructure sector, is tasked with leading the global go-to-market strategy for DG Matrix’s next-generation power platform. The company, which has developed what it calls the world's first multi-port solid-state transformer, is betting it holds the key to unlocking the power bottlenecks currently throttling the expansion of AI data centers and broader electrification projects. The hiring of a high-profile CMO suggests DG Matrix is shifting gears from a technology-focused startup to a commercial powerhouse ready to scale.

“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, in a statement. “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.”

A Playbook for Brand Transformation

Stiller’s resume reads like a blueprint for scaling technology brands. His career began at BMW before he moved into the critical power sector at APC, which was later acquired by Schneider Electric. There, he rose to Senior Vice President of Global Field and Portfolio Marketing, launching campaigns credited with generating multi-billion dollar pipeline contributions.

Most recently, as CMO of Vertiv, Stiller oversaw a significant brand transformation. He is widely credited with repositioning the company from a perceived industrial hardware supplier to an undisputed leader in the booming AI infrastructure market. During his tenure, Vertiv’s market capitalization soared, and Stiller himself garnered accolades including being named a “CMO to Watch 2024” and PR News’ “2023 People of the Year — Chief Communications Officer.”

At DG Matrix, he faces a similar challenge: translating a complex, groundbreaking technology into a compelling value proposition for a market under immense pressure. The company has already secured over $100 million in funding from investors including ABB, Chevron Technology Ventures, and Clean Energy Ventures, signaling strong confidence in its technology. Now, the focus shifts to execution and market penetration.

“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,” Stiller commented on his appointment. “I’m excited to join this talented team and help accelerate our reach into new markets and customer segments around the world.”

The AI Power Crunch

The strategic importance of Stiller’s appointment is underscored by the immense challenge his new company aims to solve. The power demands of AI are growing at an exponential rate. Industry forecasts project U.S. data center power consumption could surge from around 25 GW in 2024 to over 80 GW by 2030, an increase equivalent to the power needs of tens of millions of homes.

This explosive growth is driven by the high-density computing required for AI workloads. A single AI server rack can consume up to 100kW of power, nearly ten times that of a traditional server rack. These demands create intense power spikes and fluctuations that legacy electrical systems struggle to manage, threatening grid stability and data center uptime.

Compounding the problem are the logistical hurdles of building new power infrastructure. Connecting a new gigawatt-scale data center to the grid can take years due to regulatory delays, supply chain constraints for traditional transformers, and a shortage of skilled electrical engineers. This “speed to power” issue has become one of the single biggest obstacles to the expansion of AI capabilities.

A Solid-State Solution for a Digital Problem

DG Matrix argues that its technology, the Interport platform, offers a direct solution to these challenges. The platform is a modular, software-defined solid-state transformer (SST) that replaces a complex array of 10 to 20 legacy electrical components—including traditional transformers, switchgear, and uninterruptible power supplies (UPS)—with a single, intelligent system.

By using advanced power electronics instead of copper and steel, SSTs can convert and manage electricity with far greater precision and efficiency. DG Matrix claims its system is up to five times smaller than the equipment it replaces and operates at 98% efficiency, significantly reducing energy waste and physical footprint. Crucially, the company states its modular approach can slash the time-to-power for large-scale data centers from years down to months.

The “multi-port” design allows the Interport to seamlessly route, blend, and manage power from multiple sources—such as the grid, solar arrays, batteries, and backup generators—while simultaneously serving multiple loads. This capability is vital for creating resilient microgrids that can support critical AI operations and integrate renewable energy sources effectively.

The technology has already gained significant industry recognition. DG Matrix is an official NVIDIA MGX Ecosystem Partner, aligning its power solutions with the leading AI computing platform, and was recently named a “Top 10 Innovator in Grid Technologies” by industry research firm Darcy Partners.

From Lab to Leadership

The challenge for DG Matrix, and by extension for Rainer Stiller, is to move this advanced technology from a niche innovation to an industry standard. The SST market, while growing rapidly, includes formidable competition from established industrial giants like Siemens, ABB, and Schneider Electric.

Stiller's hiring indicates DG Matrix's strategy is not just about having superior technology, but about winning the narrative. His task will be to build a global brand, establish high-performance demand generation engines, and forge strategic alliances that can accelerate adoption. His experience building channel partner programs—once expanding a program from 250 to 4,000 resellers in a single year—will be instrumental as DG Matrix looks to expand its global footprint.

The race to power the AI revolution is on, and it is becoming increasingly clear that it will not be won solely by the company with the fastest chips. It will be won by those who can also deliver the immense, reliable, and efficient power those chips require. With the appointment of a seasoned marketing leader like Stiller, DG Matrix is making a clear statement that it intends to be a dominant force on the power side of the AI equation.
