Luminous Computing

Luminous Computing (branded simply "Luminous") is a Mountain View, California silicon-photonics company founded in 2018 by Marcus Gomez (CEO), Mitchell Nahmias (CTO) and Michael Gao (chief strategist), building an optical AI supercomputer that replaces electrical interconnect with light to remove the data-movement bottleneck between compute and memory. The architecture derives from Nahmias' neuromorphic-photonics research at Princeton, and the company's stated goal is a photonics-based machine that delivers a step-function gain in AI training and inference throughput while simplifying the programming model. Luminous emerged from stealth in March 2022 with a $105M Series A backed by Bill Gates, Gigafund, 8090 Partners, Neo, Third Kind Venture Capital, Alumni Ventures, Strawberry Creek Ventures, Horsley Bridge and Modern Venture Partners, bringing total disclosed funding to roughly $123-126M across three rounds; silicon-photonics veteran Michael Hochberg (founder of Luxtera, acquired by Cisco, and Elenion, acquired by Nokia) joined as president of engineering and operations in 2023. Luminous is a semiconductor and systems company, not a software vendor - it publishes no developer portal, no API documentation, no SDK and no machine-readable API contract of any kind. Its public web presence is a single-page marketing site; as of August 2026 the company's own domain lmns.com returns a Squarespace "Website Expired" page while the underlying site remains reachable at the platform address luminous-co.squarespace.com, and lmns.com DNS is still actively operated (Google Workspace mail, plus Atlassian, Smartsheet and DocuSign domain verifications), indicating a lapsed marketing-site subscription rather than a wound-down company.

Luminous Computing is profiled on the APIs.io network. Tagged areas include Company, Semiconductors, Silicon Photonics, Photonic Computing, and Optical Interconnect.
