Lightmatter
Lightmatter is a Boston-based optical computing company that creates photonic integrated circuits and optical interconnects.[1]
The company was founded 2017 by Darius Bunandar, Thomas Graham, and Nicholas Harris as a spin-off from Dirk Englund's lab at MIT.[1][2] They raised an $11M Series A in 2018[3], an $80M Series B in 2021[4], and a $154M Series C in 2023[5].
Lightmatter offers two products as of 2024: an ASIC that uses optical computing for LLM training called Envise, and an optical interconnect platform called Passage that connects up to 48 chips with support for up to 768 Terabits per second between each chip.[6]
