# Luminous Computing

> Mountain View, California silicon-photonics company (branded "Luminous") founded in 2018 by Marcus Gomez (CEO), Mitchell Nahmias (CTO) and Michael Gao, building an optical AI supercomputer that moves data with light instead of electricity to eliminate the interconnect bottleneck between compute and memory. The architecture derives from Nahmias' neuromorphic-photonics research at Princeton. 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; total disclosed funding is roughly $123-126M across three rounds. Silicon-photonics veteran Michael Hochberg (Luxtera, Elenion) joined as president of engineering and operations in 2023.

## APIs

Luminous Computing publishes no public API, developer portal, API documentation, SDK, CLI, or
machine-readable API contract (OpenAPI, AsyncAPI, GraphQL, gRPC/Protobuf, MCP, A2A) as of
2026-08-04. Probes of every host for /openapi.json, /openapi.yaml, /swagger.json, /api-docs,
/docs, /llms.txt and every /.well-known/ discovery path — including both
/.well-known/agent-card.json and the legacy /.well-known/agent.json — returned HTTP 404. It is a
semiconductor and systems company; its product is a photonic AI accelerator, not a service.

## Site status

- The company's own domain, https://lmns.com/, returns a Squarespace "Website Expired" page
  (HTTP 404) as of 2026-08-04.
- The same marketing site is still served at the Squarespace platform address
  https://luminous-co.squarespace.com/luminous (HTTP 200).
- https://www.luminouscomputing.com/ 301-redirects to https://lmns.com/.
- lmns.com DNS remains actively operated — Google Workspace MX plus Atlassian, Smartsheet and
  DocuSign domain-verification records — which reads as a lapsed marketing-site subscription
  rather than a wound-down company.
