Bidstack

Leading pure-play in-game advertising platform, publicly listed on AIM, specializing in native non-intrusive ad formats within video game environments

Bidstack is a pioneering AdTech company founded in 2015 and headquartered in London, United Kingdom, specializing in native in-game advertising technology. The company has built a proprietary programmatic advertising platform that allows brands and advertisers to place contextually relevant, non-intrusive advertisements within video game environments — including billboards, pitch-side banners, and other naturally occurring ad placements — across mobile, PC, and console platforms. By integrating directly into game engines and working closely with game developers and publishers, Bidstack ensures that ads feel organic to the gaming experience rather than disruptive overlays. Bidstack operates at the intersection of the rapidly growing gaming industry and the digital advertising ecosystem, offering a supply-side platform (SSP) for game publishers and demand-side access for advertisers and agencies. The company's real-time bidding (RTB) infrastructure connects premium gaming inventory with programmatic demand, enabling data-driven targeting and measurable campaign performance. Bidstack is publicly listed on the London Stock Exchange's AIM market under the ticker BIDS, giving it a distinct profile among AdTech companies in the in-game advertising space. As in-game advertising has grown into a multi-billion dollar market, Bidstack has positioned itself as a specialist pure-play provider, competing with broader platforms while emphasizing its deep gaming expertise, developer relationships, and commitment to non-intrusive ad formats. The company serves a global roster of game publishers, brands, and media agencies, and has established integrations with major demand-side platforms and ad exchanges to maximize fill rates and revenue for its publisher partners.
