Spanish spinout IPronics has raised $125 million in a Series B funding round to scale the commercialisation of its optical switches designed for AI data centres, the company announced. The round was disclosed on September 2, 2026, marking a major capital injection to accelerate growth and deployment of its technology.
The funding round saw participation from Nvidia, which is backing IPronics as it expands operations. The company plans to use the proceeds to increase commercial deployment of its optical switching technology, which aims to improve data centre efficiency for AI workloads. IPronics spun out from a university research lab and has developed proprietary optical switches that reduce latency and power consumption in AI data centres.
This funding round highlights growing investor interest in hardware innovations that support AI infrastructure. Optical switching technology is seen as a critical component for scaling AI data centres, where traditional electronic switches face limitations. Nvidia's involvement aligns with its broader strategy to support AI hardware advancements. Comparable deals in the AI hardware space have gained traction as demand for efficient data centre components rises.
IPronics will deploy the new capital to expand its commercial footprint and accelerate product rollouts. The company confirmed the $125 million Series B round on September 2, 2026, positioning it to meet increasing demand from AI data centre operators seeking advanced optical switching solutions.
