description: 'Kuehnle AgroSystems, Inc. (KAS) is a Honolulu, Hawaii microalgae biotechnology
  company founded in 2007 by Dr. Adelheid "Heidi" Kuehnle, with a second site in Cork, Ireland.
  KAS produces high-value natural products from microalgae for the food, feed and health
  markets using a patented heterotrophic "dark fermentation" process and proprietary non-GMO
  Hawaiian algal strains that run in standard fermentation equipment rather than open ponds or
  photobioreactors, compressing production from weeks to days with substantially lower cost,
  land, water and energy use. Its lead products are natural astaxanthin and algal protein,
  sold into nutraceuticals, cosmetics and skincare, functional foods and beverages, and
  aquaculture and animal feed; in August 2025 KAS entered a development and commercialization
  partnership with Corbion for an esterified natural astaxanthin. KAS sells ingredients,
  strains and fermentation process technology rather than software: it publishes no API,
  developer program, SDK, or machine-readable contract, and kuehnleagro.com is a six-page
  Squarespace marketing site.'

  detail: >-
    Kuehnle AgroSystems sells microalgae-derived ingredients — natural astaxanthin and algal
    protein produced by a patented dark-fermentation process — so software is not the product;
    kuehnleagro.com is a six-page Squarespace marketing site whose sitemap lists six URLs and
    no developer, docs or API page, there is no GitHub organization or npm/PyPI package under
    the company name, and api./docs./developer..kuehnleagro.com are wildcard DNS to a
    Squarespace address whose TLS certificate does not cover them, so no HTTPS connection to
    them is possible.
