NVIDIA Just Backed This Startup's $125M Bet on AI Data Centers

Jan de Vries · 2026-09-04

Here's a headline you don't see every day: a Spanish startup just pulled in $125 million to change how AI data centers talk to each other. And NVIDIA, the chip giant at the center of the AI boom, decided to get in on the action. That company is iPronics, based in Valencia, Spain. They just closed a massive Series B round that brings their total funding to $177 million. The round was co-led by Maverick Silicon and Light Street Capital, with NVIDIA joining as a strategic investor. Other backers include Bosch Ventures, the European Innovation Council Fund, and several others who clearly see something big happening here. ### Why Should You Care About Optical Switching? Let me break this down simply. Right now, AI data centers are hitting a wall. Not a physical wall, but a bandwidth and power wall. As AI models get bigger and more complex, the networks connecting thousands of GPUs are struggling to keep up. Copper cables just can't handle the speed and distance requirements anymore. That's where optics come in. Think of it like this: copper is like a two-lane country road, and optics are like a ten-lane superhighway. When you're moving massive amounts of AI data, you need the superhighway. And that's exactly what iPronics builds. ### The Tech Behind the Hype Founded in 2019 as a spin-off from Universitat Politècnica de València, iPronics has developed something called optical circuit switching (OCS) technology. Their flagship product, the iPronics ONE, is a rack-mounted optical switch designed specifically for AI infrastructure. It's compact, purpose-built, and can be deployed right into existing data center racks. The cool part? It uses silicon photonics, which means it's built using similar manufacturing processes to computer chips. This makes it smaller, more efficient, and potentially cheaper to scale than traditional optical equipment. The system allows data centers to reconfigure their networks in real-time, which means better GPU utilization and lower energy consumption. ### What the Money Means for the Company According to Christian Dupont, CEO of iPronics, this funding will significantly accelerate their commercialization efforts. The company is already expanding its presence in the United States, having opened a new office in Santa Clara, California. They're actively hiring to strengthen their product strategy and build out their AI infrastructure partnerships. Here's what the company plans to do with the cash: - Scale up manufacturing of their iPronics ONE platform - Expand their U.S. operations and customer deployments - Build out their engineering and product teams - Strengthen partnerships with hyperscalers and AI infrastructure providers ### A Vote of Confidence from Industry Heavyweights When NVIDIA decides to invest in your company, that's a pretty strong signal. The chip maker has been at the forefront of the AI revolution, and their GPUs power most of the world's AI data centers. If NVIDIA sees value in iPronics' technology, it suggests that optical switching is becoming a critical piece of the AI infrastructure puzzle. Manish Muthal, senior managing director at Maverick Silicon, is joining iPronics' board of directors. Geoffrey Tate, an advisor to Light Street Capital, is also joining the board. And Young Sohn of Catalight Capital, who runs a fund focused specifically on AI infrastructure, is becoming an advisor to the company. "The explosive growth of AI workloads has pushed traditional network infrastructure to its power and bandwidth limits," Muthal said. "Making optical circuit switching more critical than ever." ### The Bigger Picture This isn't just about one company raising money. It's about the fundamental shift happening in how we build AI infrastructure. As AI clusters grow, the transition from copper to optics is accelerating. Companies that can deliver high-density, scalable switching solutions are going to be in high demand. The fact that iPronics is a Spanish company breaking into the U.S. market is also noteworthy. It shows that European innovation in deep tech is alive and well, and that American investors are willing to bet big on it. With this kind of backing, iPronics is positioning itself as a serious player in the optical networking space, right alongside much larger competitors. For anyone watching the AI infrastructure space, this is a company worth keeping an eye on. They've got the technology, the funding, and now the strategic partners to make a real dent in how AI data centers operate.
