GumGum

aid: gumgum
name: GumGum
description: GumGum is a Santa Monica-based advertising technology company, founded in 2008, that sells contextual, CTV/online-video
  and high-impact display advertising built on its own content intelligence. Its GumGum Contextual platform (formerly Verity)
  uses in-house computer vision and natural language processing to read the text, images, video and audio of a page or asset
  before the bid, returning IAB Content Taxonomy classifications (v1, v2 and v3), extracted keywords, named entities, brand-safety
  and suitability threats, and sentiment. That analysis is exposed to publishers, DSPs, agencies and advertisers as a server-to-server
  REST API at verity-api.gumgum.com with separate Page, Video, Intravideo, Image and Text surfaces, plus an asynchronous webhook
  callback for delivering completed classifications. GumGum also ships an open-source Prebid.js bid adapter for header bidding,
  and holds Media Rating Council accreditation for content-level classification across desktop, mobile web and CTV.
