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.
