Viridos

Viridos, founded in 2005 as Synthetic Genomics, Inc. by J. Craig Venter and Hamilton Smith and renamed Viridos in September 2021, was a La Jolla, California synthetic-biology company that engineered microalgae genomes to produce low-carbon-intensity biofuels, running its algal biofuel program as a long-term research partnership with ExxonMobil. The company never published an API, a developer portal, or any machine-readable contract; its only public developer surface was a GitHub organization holding two first-party open-source projects - the AGPL-licensed sgidspace deep-learning protein annotation library and a sensor calibration app - alongside seven forks of third-party tools. Viridos filed for Chapter 11 bankruptcy 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. Its website has served no content since roughly October 2025.

Viridos is profiled on the APIs.io network. Tagged areas include Company, Synthetic Biology, Biotechnology, Genomics, and Biofuels.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/synthetic-genomics: open an issue to ask a question, or submit a pull request to add artifacts.

x-notes:
  website-pointer-removed: 'The stub carried type Website pointing at https://forgeglobal.com/synthetic-genomics_stock/. Forge
    Global is a secondary-market trading venue, not Viridos, so that URL is not the company''s web presence and has been retyped
    as SecondaryMarketListing (roadmap#56). No Website pointer is emitted in its place: the company''s own domain, viridos.com,
    returns "403 | Access blocked" on every path from a SiteGround default vhost behind a certificate that does not cover
    the domain.'
  legacy-domain-warning: syntheticgenomics.com returns HTTP 200 but is NOT this company. The legacy domain was dropped and
    now hosts a Canadian online-casino affiliate site on Cloudflare. It must never be wired as a Website or Blog pointer for
    this profile.
  no-wellknown-pointer: well-known/synthetic-genomics-well-known.yml records the probe of 20 /.well-known and contract-discovery
    paths across viridos.com and dspace.bio. Every one returned 403, so no WellKnown or SecurityTxt pointer is emitted - the
    file documents an absence, not a surface.
  not-sgi-dna: SGI-DNA, the DNA synthesis instrument business separated from Synthetic Genomics (later Codex DNA / Telesis
    Bio), is a different company. Do not attribute its products or APIs here.
