iPronics Raises $125M for AI Optical Switching
iPronics raised about $125M to scale optical switching technology for AI data-centre networking.
AI data centres are creating bottlenecks far below the model layer: chips and racks need faster ways to communicate.
What happened
Valencia-based iPronics raised roughly $125M in Series B funding, with Nvidia joining the round. The company builds optical circuit-switching technology for AI data-centre networking.
Its technology targets the communication layer inside large AI clusters, where traditional copper-heavy systems can become costly, power-hungry and harder to scale.
Why it matters
AI performance is increasingly limited by the infrastructure around GPUs, not just by the GPUs themselves. As clusters get larger, data movement becomes one of the most important constraints.
Optical switching offers a route to faster, lower-power interconnects, which could help data centres run larger AI workloads more efficiently.
The bigger picture
The AI infrastructure stack is fragmenting into many investable layers: chips, power, cooling, networking, memory and software orchestration. iPronics shows that optical networking is becoming a serious part of the AI buildout, not just a telecom niche.
