Lightmatter Inc., a startup making computing products that use light in place of electricity, has raised a new round of funding that almost quadruples its valuation to $4.4 billion.
The company, which aims to overhaul the market for artificial intelligence computing power using the still-early technology, said Wednesday that it brought in $400 million in a Series D financing, led by new investor T. Rowe Price Associates. Existing investors such as GV, formerly known as Google Ventures, also participated in the round, the company said.
