iPronics Raises $125M Series B for Optical AI Networking
Spanish optical networking startup iPronics raised $125 million in a Series B round led by Maverick Silicon and Light Street Capital, with participation from NVIDIA, Bosch Ventures, Catalight Capital, and the European Innovation Council fund. The company, a 2019 spin-off of València's Technical University, has now raised $177 million total. iPronics develops optical circuit switches (OCS) for AI data centers, a technology proven by Google in its TPU clusters. Its ONE-32 switch offers sub-30-nanosecond latency and reconfiguration under 300 microseconds, cutting switching power consumption by up to 50 percent. The funding will shrink the hardware roughly 20-fold, expand commercial operations, and support its new Silicon Valley office in Santa Clara. NVIDIA's participation underscores rising industry demand for optical interconnect as AI clusters hit power and bandwidth limits.

US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
