iPronics raises $125M from Nvidia and others for chips that rewire data centers in sub-milliseconds

A Spanish startup that spun out of a university lab seven years ago just landed $125 million to help the world’s biggest data centers stop wasting their most expensive hardware. iPronics, headquartered in Valencia, closed its Series B round on September 2, with Maverick Silicon and Light Street Capital co-leading the deal. Nvidia participated alongside other investors, bringing the company’s total funding to $177 million. What iPronics actually builds The core product is called the ONE platform, and it does something deceptively simple: it lets data centers physically rewire their internal connections on the fly. Traditional networking gear forces operators to pick a topology and live with it. iPronics uses silicon photonics to create optical circuit switches that can reconfigure in sub-milliseconds. The practical upside is twofold. First, GPUs spend less time sitting idle waiting for data from other parts of the network. Second, the whole setup draws less power. For hyperscalers deploying hundreds of thousands of computing accelerators in a single facility, even marginal efficiency gains translate into meaningful cost savings. Perhaps the most striking claim: iPronics says its swi...
