# Nvidia Backs Spanish Startup iPronics in $125M AI Networking Round

> iPronics, a Spanish semiconductor startup, has raised $125 million in a round that includes backing from Nvidia, aimed at its programmable photonic chips for AI data centers. Rather than moving data with electrical signals, the company's chips use light, which promises far higher bandwidth and lower power for shuttling information around. The problem it targets is one of the quieter bottlenecks in AI infrastructure. Everyone focuses on GPUs, but a large training cluster has to connect thousands to hundreds of thousands of accelerators, and the interconnects between them increasingly limit how fast the whole system can go. Photonics is one of the most promising ways past that wall. Nvidia's involvement is the tell. The company dominates the accelerators themselves, so betting on a networking startup signals where it sees the next constraint, and lends credibility to a European player in a field usually dominated by American and Asian firms. For iPronics, both the cash and the strategic backer matter as it tries to move photonic networking from promise to production.
