Optical Networking Firm Lumilens Valued at $5.5 Billion in Latest Funding Round Optical networking startup Lumilens announced on Thursday that it has reached a valuation of $5.51 billion following its latest funding round. The company, based in San Jose, California, designs and manufactures optical and networking products that enable data centers to transfer data at high speeds while using less power. The surge in investment in AI data centers has driven demand for such technologies, according to the firm. Lumilens raised more than $700 million in its Series C funding round, which was co-led by Atreides Management, Bain Capital Ventures, Meritech, Seligman Ventures, and Spark Capital. This brings the company’s total funding to over $900 million. The funding round reflects the growing interest in optical networking solutions as hyperscalers expand their data centers to meet the rising demand for artificial intelligence services. The company is already shipping products under a multi-billion-dollar agreement with a customer it has not disclosed. It confirmed the customer is one of the four hyperscalers—Amazon, Alphabet, Microsoft, and Meta. The data center boom, driven by the expansion of AI services, is increasing the need for networking technologies that can efficiently connect thousands of GPUs. Lumilens CEO Ankur Singla noted that the primary constraint for hyperscalers has shifted from the availability of GPUs to the ability to connect them. “Hyperscalers told us they need the same two things: far more optical capacity for the networks they run today, and a path to directly connecting thousands of GPUs together into a single cluster,” Singla said. The company plans to use the fresh capital to scale up its engineering and manufacturing operations.#lumilens #atrides_management #bain_capital_ventures #meritech #seligman_ventures
