# Viridos (formerly Synthetic Genomics, Inc.)

> Viridos was a La Jolla, California synthetic-biology company applying genome engineering to
> microalgae for low-carbon-intensity biofuels. It is no longer operating: it filed Chapter 11 in
> the District of Delaware on 2025-04-14, sold substantially all of its algae biofuel technology to
> Breakthrough Energy Ventures II, L.P., and the case was dismissed on 2025-11-26. This file is

## Status

- Operating status: defunct. Assets sold; no successor developer surface has been published.
- Website: viridos.com resolves but serves nothing. Every path returns a 21-byte
  "403 | Access blocked" page from a SiteGround default vhost, behind a TLS certificate issued for
  giowm1252.siteground.biz that does not cover the domain. The last substantive archived snapshot
  is 2025-09-11; by 2025-10-22 the page had collapsed to roughly 1.4 KB.
- DNS and corporate mail for viridos.com are still live and enterprise-configured (Mimecast
  inbound, Microsoft 365 sending, SPF -all, DMARC p=reject), which outlasted the website.
- Legacy domain warning: syntheticgenomics.com returns HTTP 200 but is NOT the company. The domain
  was dropped and is now a Canadian online-casino affiliate site on Cloudflare. Do not treat it as
  a Viridos source, and do not cite anything published there to this company.

## API surface

- No API. Viridos never published a developer portal, an API reference, or a machine-readable
  contract of any kind.
- Contract discovery run 2026-08-29 against viridos.com and dspace.bio - /openapi.json,
  /openapi.yaml, /swagger.json, /v1/openapi.json, /api-docs, /api, /.well-known/api-catalog,
  /.well-known/ai-plugin.json, /.well-known/openid-configuration,
  /.well-known/oauth-authorization-server, /.well-known/security.txt,
  /.well-known/agent-card.json, /.well-known/agent.json, /llms.txt - returned 403 on every path.
- No GraphQL endpoint, no MCP server, no A2A agent card, no AsyncAPI or webhook surface, no SOAP
  or gRPC contract was found on any host or in the GitHub organization.
- api., developer., docs., app. and dspace. subdomains of viridos.com do not resolve.
