Prebid

Prebid operates a consortium-style business model built around open-source adtech infrastructure and ecosystem governance. It creates value by maintaining common technical standards, software libraries and interoperability layers that publishers and ad tech vendors can adopt without direct licence fees. The organisation is funded through paid membership, while implementation, hosting and operational services are often delivered by member companies and ecosystem partners rather than by Prebid itself.

Prebid is a US-based not-for-profit organisation that develops, maintains and governs open-source infrastructure for programmatic advertising, primarily around header bidding. Its core products include Prebid.js for web header bidding, Prebid Server for server-side auction orchestration, Prebid Mobile for in-app bidding, SharedID for publisher-centric identity, and analytics and operational tooling for monetisation workflows. Its main customers and users are digital publishers, app publishers, ad operations teams, developers and ad tech companies participating in the open web advertising ecosystem.

Prebid does not primarily make money by licensing its core software. Instead, it funds ongoing development and governance through paid organisational membership dues, with pricing linked to member type and revenue. Value is created by providing open, interoperable standards and software that help publishers reduce dependency on closed platforms, access multiple demand partners and improve auction transparency and yield.
