4Info

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.

4Info is profiled on the APIs.io network. Tagged areas include Company, Advertising, AdTech, Mobile Advertising, and Advanced TV.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/4info: open an issue to ask a question, or submit a pull request to add artifacts.

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

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).

    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.
