iPronics Raises $125M Series B for Optical Switches, Nvidia Invests
Spanish startup iPronics, a spin-off from the Technical University of Valencia, has raised a $125 million Series B round to scale its optical circuit switch technology for AI data centers. The round was led by Maverick Silicon and Light Street Capital, with participation from Nvidia, Bosch Ventures, Catalight Capital, and others. The company's product, iPronics ONE, uses photonic switching to route data in AI clusters, reducing latency and power consumption by up to 50%. Funding will be used to shrink the hardware by roughly 20x, expand operations, and accelerate commercialization. The round brings total funding to $177 million. iPronics already ships its ONE-32 switch to unnamed Tier-One infrastructure providers and plans to open a Silicon Valley office.
This $125M Series B with Nvidia participation highlights the growing importance of photonic networking for AI infrastructure, a key area for the future of ad tech data processing and cloud computing.
