description: Greyter Water Systems Inc. was an Ontario, Canada manufacturer of onsite greywater
  recycling and water reuse systems, founded in 2012 after acquiring the assets of the defunct
  Brac Systems. Its flagship Greyter HOME captured water from showers and bathtubs, treated it,
  and returned clear, odor-free water for toilet flushing, cutting a family home's indoor water
  consumption by up to 25 percent; it earned NSF/ANSI 350 Class R certification in early 2019 as
  the first compact residential greywater reuse system to hold that designation. A scaled
  commercial line served water harvesting and reuse for toilet flushing and cooling towers in
  multi-unit and institutional buildings, and the systems were installed in more than a dozen
  countries. The company raised roughly $13M through a Series B. Its only software was an
  end-user monitoring surface — the mygreyter.com portal and a consumer Greyter mobile app used
  by owners to watch water savings — and it never published a developer program, public API, SDK,
  webhooks, or any machine-readable specification. Greyter Water Systems Inc. filed for bankruptcy
  on January 8, 2026, with GlassRatner Restructuring Inc. appointed Trustee and its intellectual
  property, patents and customer lists placed into an asset sale process. This profile is retained
  as a historical record; there is no API surface to enrich.

x-domain-note: 'greyter.com is no longer operated by the company. It is a GoDaddy parked domain
  (ns71/ns72.domaincontrol.com): every path — including /openapi.json, /graphql, /mcp and every
  /.well-known/* location — returns the identical 114-byte HTML stub that redirects to /lander,
  and sitemap.xml lists only /lander. The /robots.txt and /llms.txt served there are GoDaddy
  parking-lander boilerplate, not provider-published documents, and are deliberately NOT wired
  as pointers. The last live archived snapshot of the real site is 2026-06-08. mygreyter.com,
  the customer portal, still resolves through Cloudflare but its origin is dead (HTTP 526).'
x-harvest-note: The inherited stub carried a Website pointer to https://www.nasdaqprivatemarket.com/,
  which is the secondary-market harvest SOURCE and not this company's website. It was a
  misattribution and has been removed.

  detail: Greyter Water Systems Inc. filed for bankruptcy on 2026-01-08 with GlassRatner
    Restructuring Inc. as Trustee, and greyter.com is now a GoDaddy parked domain that answers
    every path — /openapi.json, /graphql, /mcp and all /.well-known/* included — with the same
    114-byte redirect to /lander, while the mygreyter.com customer portal origin returns
    Cloudflare 526.
