AirGrid

AirGrid operates as an advertising technology infrastructure and audience platform sitting between publishers and programmatic buyers. It provides a client-side library that runs in the browser to create and attach cookieless audience signals to ad bid requests, and a central platform that manages audience definitions, measurement and commercial activation.

Value is created for publishers by enabling them to monetise their first-party data in a privacy-preserving way across all browsers, while retaining control of raw data on-device. For marketers and agencies, the platform offers addressable, cookieless audiences accessible via programmatic Private Marketplace (PMP) deals. AirGrid likely integrates with header-bidding and SSP ecosystems, orchestrates managed deals, and supplies analytics on incremental yield and performance, effectively functioning as a publisher yield and audience infrastructure layer within the adtech stack.

AirGrid is a UK-based advertising technology company acquired by MiQ that provides a privacy-focused, cookieless audience platform for digital advertising. Its technology performs audience creation and modelling directly on users’ devices using edge compute and on-device machine learning, generating audience signals without third-party cookies and without sharing raw first-party data with third parties.

The company serves digital publishers that want to monetise their first-party data and programmatic marketers or agencies that buy audience-targeted inventory via Private Marketplace (PMP) deals. AirGrid connects publishers and marketers, appends cookieless audience signals to bid requests via a client-side library, and activates demand through managed PMP deals, earning revenue via a share of media spend and platform or service fees.
