Overview
Lumilens designs and manufactures optical interconnects for AI data centers from San Jose. The LumiCore platform spans near-package and co-packaged optics for GPU scale-up plus 800G/1.6T+ pluggable transceivers for scale-out fabrics. Founded in 2024 by Ankur Singla, the company says it is already shipping into a top hyperscaler’s production AI clusters under a multi-billion-dollar agreement. Series C (> $700M at $5.51B) was co-led by Atreides, Bain Capital Ventures, Meritech, Seligman Ventures, and Spark Capital, with Addition, Redpoint, Qualcomm Ventures, and others participating — more than $900M raised total.
Why Lumilens is interesting
Emerged from stealth (Aug 2026) with >$700M Series C at $5.51B and a multi-billion hyperscaler shipping agreement — AI’s bottleneck shifted from buying GPUs to wiring them.
Product & use cases
Full optical connectivity stack for AI clusters: NPO/CPO for in-rack GPU scale-up and high-speed pluggables for rack-to-rack scale-out, built on in-house silicon photonics and manufacturing processes.
- Scale-out optical capacity for massive GPU fabrics
- Scale-up optical I/O to couple thousands of GPUs as one system
- Diversify hyperscaler optics supply beyond legacy copper limits

Competitive landscape
Edge: Two-year path from founding to hyperscaler production plus a unified LumiCore platform spanning scale-up and scale-out with manufacturing treated as a product.
As AI clusters grow, interconnect scarcity rivals GPU scarcity. Lumilens sells production optics into that gap; customer concentration and manufacturing yield are the underwriting risks.
-
Incumbent optics vendors (Coherent, Lumentum, etc.) incumbent
Volume pluggables; different full-stack NPO/CPO + manufacturing story.
-
Nvidia / in-house photonics adjacent
Strategic competitor-partner dynamic on scale-up optics.
-
Other CPO/NPO startups direct
Crowded interconnect category decided by design-wins and yield.
-
Point2 Technology direct
RF e-Tube cables (Series B total $136M, Aug 10, 2026) attacking the same AI rack-wiring job with a different physics; no named production customer in that PR.
