Lumilens raises over $700 million at $5.51 billion valuation
The optical networking startup said the Series C round lifts total funding above $900 million as AI data-center expansion drives demand for faster, lower-power links across large GPU clusters.
Lumilens said it raised more than $700 million in a Series C round valuing the company at $5.51 billion, as heavy spending on AI data centers boosts demand for faster, more power-efficient connectivity. The San Jose, California-based optical networking startup said the financing was co-led by Atreides Management, Bain Capital Ventures, Meritech, Seligman Ventures and Spark Capital, bringing total funding to more than $900 million. Lumilens said it is already shipping products under a multi-billion-dollar agreement with an unnamed customer that it said is one of the four hyperscalers: Amazon, Alphabet, Microsoft or Meta. CEO Ankur Singla said the bottleneck in AI infrastructure has shifted toward linking large numbers of GPUs, and the company plans to use the new capital to expand engineering and manufacturing.
- optical networking: Technology that uses light-based components to move data quickly between computing and network systems.
- hyperscalers: Very large technology companies that run massive cloud and data-center infrastructure.
- GPU clusters: Large groups of graphics processors connected together to handle AI computing workloads.
