Greyter

aid: greyter
name: Greyter
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.
