Lightmatter Relocates to Silicon Valley and Secures $400M Funding

The AI chipmaker's move to California coincides with a significant funding round, valuing the company at $4.4 billion.

Lightmatter, a pioneer in photonic computing, has moved its headquarters from Boston to Mountain View, California.
The company raised $400 million in a Series D funding round led by T. Rowe Price, with participation from Fidelity and GV.
Lightmatter's valuation has surged to $4.4 billion, nearly quadrupling since its last funding round less than a year ago.
The new capital will be used to manufacture and deploy its photonic chips in data centers, as well as expand its workforce.
CEO Nick Harris indicated this might be the last private funding round before a potential public offering.
