description: '4INFO, Inc. was a San Mateo (originally Palo Alto) California advertising-technology company
  founded in 2004 by Pankaj Shah and Zaw Thet. It began as an SMS content and alerting service — Nielsen
  called it the largest business-to-consumer SMS content provider in North America in 2008 — then pivoted
  in 2010 into mobile display advertising with the AdHaven platform, a mobile ad server, audience data-management
  and analytics stack sold to publishers, aggregators and national advertisers. Its later product was
  an identity graph: patented technology ("Systems and methods for statistically associating mobile devices
  to households") that statistically resolved mobile devices, set-top boxes and connected TVs back to
  a single household so brands could target and measure across screens. mBlox bought the legacy SMS business
  in 2015, and Cadent acquired the remaining company in January 2020, folding the identity and cross-screen
  targeting technology into Cadent''s advanced-TV platform. 4INFO no longer operates as an independent
  company: 4info.com is retained for email only and publishes no A or AAAA record, so there is no website,
  developer portal, API reference or machine-readable contract of any kind on any 4Info host, live or
  archived.'

x-acquisition-note: Cadent announced the acquisition of 4INFO on 2 January 2020; all 30 4INFO employees
  joined Cadent. The GitHub organization github.com/4info is still named "4info Organization (Cadent)".
  Cadent's own surface (cadent.com) is a separate company record and is deliberately NOT wired here as
  a 4Info property.
x-domain-status: mail-only
x-domain-note: 4info.com is delegated to AWS Route 53 and carries live Proofpoint MX, SPF and DMARC records,
  but publishes NO A or AAAA record on the apex or on www — every HTTP request fails at DNS resolution
  (curl exit 6, status 000). The last Internet Archive capture of the site is 2023-02-02 and the following
  capture, 2023-05-28, was a 404. There is no host to wire as a Website pointer. The forgeglobal.com/4info_stock/
  URL this record was harvested from is a third-party secondary-market venue listing, not 4Info's web
  presence, so it is recorded as x-harvest-source-url rather than as a Website pointer (roadmap#56).

  reason: defunct
  detail: 4INFO was fully absorbed into Cadent in January 2020 and its domain is now mail-only — 4info.com
    and www.4info.com publish no A or AAAA record at all, so every HTTP and /.well-known probe fails at
    DNS resolution rather than returning a page, and the last Internet Archive capture of the site (2023-02)
    is followed by a 404.
