DG Matrix has just crossed a serious threshold, closing an oversubscribed $60 million Series A round that pushes its total funding past the $100 million mark and quietly signals a shift from promising cleantech breakthrough to real, deployable infrastructure. The round was led by Engine Ventures, with participation from Helios Climate Ventures, Mitsubishi Heavy Industries, Fine Structure Ventures, MCJ, and Sabanci Climate Ventures, while all existing investors doubled down, including ABB. That kind of unanimous re-commitment doesn’t happen by accident; it usually shows up when technology has already escaped the lab and is starting to matter in the field.
The timing is not subtle. AI workloads are pulling electricity demand forward at a pace the grid was never designed to handle, and traditional transformer infrastructure simply moves too slowly for data centers measured in gigawatts and deployment timelines measured in months. DG Matrix’s answer is its Interport platform, described as the world’s first commercial multi-port solid-state transformer, designed to compress time-to-power from years into something closer to an operational planning cycle. Instead of forcing developers to choose between grid, solar, batteries, or generators, Interport treats them as modular inputs, integrated at scale, with pulse-load readiness built in. It’s infrastructure that assumes volatility and density are the new normal.
According to CEO Haroon Inam, this round marks a clear pivot point, less about proving the concept and more about deploying it everywhere it’s needed. DG Matrix is already working with hyperscalers, energy companies, and industrial customers across North America and beyond, with multiple gigawatt-class data centers lined up. The new capital is earmarked for scaling manufacturing and supply chains, expanding engineering and field deployment teams, and pushing through UL, IEEE, and international certifications so the platform can move freely across global markets. There’s a sense here of urgency rather than experimentation, as if the company knows the window for reshaping power infrastructure is open right now, not later.
What’s giving the story extra weight is the growing stack of external validation. DG Matrix recently announced a strategic partnership with Exowatt, the a16z- and Sam Altman-backed renewable energy company, to deliver behind-the-meter, gigawatt-scale power systems for hyperscale data centers. Exowatt selected Interport as the preferred power-conversion layer for its modular generation and storage systems, a strong signal that DG Matrix’s technology can meet the brutal uptime and power-quality demands of AI compute. Add to that its inclusion in the 2026 Global Cleantech 100 and a collaboration with PowerSecure, part of Southern Company, and the pattern becomes hard to ignore: this isn’t an isolated innovation, it’s starting to look like a new default architecture.
Engine Ventures’ Michael Kearney put it bluntly, calling DG Matrix the kind of infrastructure innovation the energy transition actually needs, not as a theoretical upgrade but as something already working in commercial deployments. Helios Climate Ventures echoed that sentiment, framing Interport not as an incremental improvement but as the modern grid architecture required to power AI data centers and mass electrification at scale. That phrasing matters. It suggests a break from patching legacy systems and toward redesigning how electricity is managed, distributed, and deployed under extreme demand.
Taken together, the Series A feels less like a funding announcement and more like a quiet acknowledgment that power infrastructure is becoming the bottleneck of the AI era, and that whoever solves it fastest will shape the next decade of compute. DG Matrix is betting that solid-state, multi-port transformers are that solution, and with $60 million in fresh capital and heavyweight partners on board, it now has the runway to prove it at industrial scale.
