iPronics Raises $125M Series B for AI Optical Switches
Spanish startup iPronics, a spin-off from the Technical University of Valencia, announced a $125 million Series B round led by Maverick Silicon and Light Street Capital, with participation from Nvidia and other investors. The company develops optical circuit switches (OCS) for AI data center networks, including the ONE-32, which offers sub-30 nanosecond latency and up to 50% lower switching power consumption. iPronics has raised $177 million in total. The new funding will be used to shrink the hardware by roughly 20x, expand operations, and accelerate commercialization. The company recently opened an office in Santa Clara and is working with contract manufacturer Fabrinet on a packaging and assembly line. New board members include Manish Muthal and Geoffrey Tate, with Young Sohn joining as advisor.
Major funding for an optical interconnect startup highlights the scaling of AI data center infrastructure, which indirectly supports AI-driven advertising and marketing platforms, but the news is not directly about AdTech.

US suspends Microsoft, Adobe from green card labor program
The U.S. Department of Labor announced the suspension of Microsoft and Adobe from its Permanent Labor Certification program, along with Cognizant, Infosys, Capgemini, Tata, Wipro, and HCL. Secretary Keith Sonderling cited active federal investigations for Microsoft and Adobe, and criticized the companies for allegedly taking jobs from American workers. Vice President JD Vance specifically accused Microsoft of replacing laid-off workers with H-1B visa holders. Microsoft responded by defending its hiring practices, stating that the majority of its U.S. employees are Americans and that most H-1B petitions are for existing employees. The announcement was made during a White House summit on H-1B fraud, coinciding with President Trump honoring several tech CEOs with the National Medal of Science.
