Bidstack

A leading specialist in intrinsic in-game programmatic advertising, publicly listed on the London Stock Exchange AIM market

Bidstack is a pioneering AdTech company specializing in in-game advertising technology, operating at the intersection of the gaming and digital advertising industries. The company has developed a proprietary programmatic advertising platform that enables brands to deliver contextually relevant, non-intrusive advertisements within video game environments — including billboards, stadium hoardings, and other native placements that exist organically within game worlds. Bidstack's technology supports real-time bidding (RTB) and integrates with major demand-side platforms (DSPs) and supply-side platforms (SSPs), making in-game inventory accessible to programmatic buyers at scale across mobile, PC, and console platforms. Bidstack works with game developers and publishers to monetize their titles through immersive, non-disruptive ad formats that do not interrupt gameplay. This approach differentiates Bidstack from traditional interstitial or rewarded video ad formats, positioning it as a specialist in intrinsic in-game advertising. The company has built partnerships with major game studios and sports simulation titles, and its SDK enables seamless integration of ad placements into game engines. Bidstack is publicly listed on the AIM market of the London Stock Exchange under the ticker BIDS, giving it a degree of transparency and credibility uncommon among smaller AdTech firms. Bidstack competes in the rapidly growing in-game advertising segment alongside players such as Anzu, Frameplay, and Admix (now part of Azerion). Its focus on intrinsic, contextually native ad formats — rather than overlay or interruptive ads — represents a key differentiator as brands seek more authentic ways to reach the highly engaged gaming audience. The company serves both brand advertisers and game publishers, acting as a marketplace that connects supply and demand within the gaming ecosystem.
