Lumilens emerged from stealth in August 2026 with more than $900M in total funding, announcing over $700M in new financing co-led by Atreides Management, Bain Capital Ventures, Meritech, Seligman Ventures and Spark Capital at a $5.51B valuation. Founded ~2024 by CEO Ankur Singla, the company builds optical interconnects for AI data centers — both scale-up networks connecting GPUs inside tightly coupled systems and scale-out networks linking racks and clusters — to address the growing bottleneck as GPU deployments outpace optical networking capacity. Its LumiCore platform spans silicon photonics, mixed-signal ICs, electrical-optical interposers and optical systems. Lumilens is already shipping into production AI data centers via a multibillion-dollar customer agreement with a major hyperscaler.
