Spain-based iPronics has raised $125m in Series B funding to accelerate the commercial deployment of its silicon photonics-based optical circuit switching (OCS) technology for AI-focused data centres.
The investment round was co-led by Maverick Silicon and Light Street Capital, with the participation of Nvidia and other new and existing backers. Total funding for iPronics currently stands at $177m.

Experience unmatched clarity with a single platform that combines unique data, AI, and human expertise.
The funding is intended to support the scale-up of iPronics’ operations and meet increasing demand for its optical networking solutions within AI data centre environments.
According to the company, shifting from copper to optics is becoming necessary as AI clusters grow and require higher bandwidth and greater flexibility.
iPronics has developed the iPronics Optical Networking Engine (ONE), a rack-mounted programmable optical switch designed to provide dynamic reconfiguration of data centre connectivity for training and inference workloads.
iPronics CEO Christian Dupont said: “Securing this support from Maverick Silicon, Light Street Capital and Nvidia strengthens our vision as we build iPronics into a new class of optical networking leaders.
“With this investment, we can significantly accelerate our commercialization, delivering the scale our customers need to drive broad adoption and ensuring data centres can fully utilize their GPUs without compromising performance.”
Maverick Silicon senior managing director Manish Muthal will join the iPronics board.
Muthal said: “The explosive growth of AI workloads has pushed traditional network infrastructure to its power and bandwidth limits, making optical circuit switching more critical than ever. We’re proud to co-lead this round and partner with the iPronics team, as they expand commercial deployments worldwide.”
The funding round also adds board-level experience with Geoffrey Tate, an adviser to Light Street Capital, joining the board, and Young Sohn of Catalight Capital becoming an adviser to the company.
Founded in 2019 as a spin-off from Universitat Politècnica de València, Spain, iPronics has opened a new office in Santa Clara, California, to support product strategy, customer deployments, and partnerships in AI infrastructure.
The company’s technology is aimed at helping data centre operators address power, cost, and complexity challenges as AI deployments scale.
