Lightmatter Inc., a startup building computing products that use light in place of electricity, has raised additional financing, pushing its valuation to $1.2 billion.
Lightmatter said Tuesday that it raised $155 million in a deal led by GV, the firm formerly known as Google Ventures, and Viking Global Investors. The funding is an extension of a Series C financing in May that brought in $154 million. The startup, which has 150 employees, has raised more than $420 million thus far.
