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

Key facts

  • Series C (Aug 2026): >$700M at $5.51B; >$900M cumulative (company)
  • Co-leads: Atreides, Bain Capital Ventures (/fund/bain-capital-ventures), Meritech, Seligman, Spark Capital (/fund/spark-capital)
  • Participants include Addition (/fund/addition) and Redpoint Ventures (/fund/redpoint-ventures)
  • Shipping into hyperscaler production under multi-billion agreement (company)
  • Addresses copper’s ~1.5m reach limit for AI scale-up fabrics

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.
