Lightmatter
62 open jobsGeneral information
Lightmatter builds photonic chips and co-packaged optics that connect the chips inside AI supercomputers. It works on solving the bandwidth limits that slow down large AI systems. Products include the Passage Interconnects (L200 and L20 models) and the Guide VLSP Light Engine.
The company reached a $4.4 billion valuation as of October 2024, after raising $850 million in total funding. That kind of backing lets a hardware startup keep building custom chips, a capital-heavy bet next to most software-only AI companies. Lightmatter is an H-1B sponsor.1
