Lightmatter is leading the revolution in AI data center infrastructure, enabling
the next giant leaps in human progress. The company invented the world’s first
3D-stacked photonics engine, Passage™, capable of connecting thousands to
millions of processors at the speed of light in extreme-scale data centers for
the most advanced AI and HPC workloads.
Lightmatter raised $400 million in its Series D round, reaching a valuation of
$4.4 billion. We will continue to accelerate the development of data center
photonics and grow every department at Lightmatter!
