What Underdog Media does

Underdog Media is a digital ad monetization platform founded in 2007 and headquartered in Santa Barbara, California. The company operates a two-sided programmatic advertising marketplace connecting online publishers with advertisers through proprietary ad unit technology. Its flagship product is EDGE by UDM, a suite of 100% viewable adhesion ad units — including Sticky Header, Sticky Footer, In-Page, In-Page Slide, Rails, Outstream Video, and Sidebar Slide — engineered with content detect technology that preserves user experience while keeping ads visible throughout the page session. The technology is deployed across more than 1,000 publisher websites globally and integrates with major ad infrastructure including Comscore, Xandr, Google Ad Manager, Magnite, Prebid, Sonobi, Confiant, Index Exchange, and MediaNet.

Underdog Media generates revenue through programmatic real-time bidding, taking a commission or revenue share on ad placements across publisher inventory. Its go-to-market combines a self-serve publisher signup (gated by minimum thresholds of 90 days of traffic history and 10,000 daily pageviews) with a dedicated account management team for higher-touch accounts, plus direct advertiser outreach. The platform layers identity resolution providers — 33Across Lexicon, SharedID, Yahoo ConnectID, and Unified ID — to monetize cookieless inventory, and maintains a Quantcast Choice CMP recommendation for GDPR/CCPA compliance. Certifications span GDPR/UK GDPR (IAB TCF v2 Vendor ID 159), CCPA/CPRA, DAA/EDAA self-regulatory frameworks, and Better Ads Standards. In September 2025, Underdog Media was acquired by Ad.com Interactive Media, Inc. and integrated under the Advertising.com portfolio, with founder Shayne Mihalka continuing as CEO. The company is structured as Underdog Media LLC, domiciled in California, with a leadership team spanning operations, sales, and development functions.
