Prebid

The organisation operates as a Delaware non-stock entity that creates and maintains open-source advertising technology infrastructure. Value is created by providing neutral, interoperable code and specifications for header bidding, identity, and privacy that publishers and adtech vendors can adopt without licence fees, reducing dependence on proprietary walled gardens and enabling competition among demand sources.

Rather than monetising media or charging usage fees, it monetises ecosystem participation: companies that benefit from the projects support them via annual membership dues. In turn, members influence roadmaps and governance while gaining a stable, community-driven technical foundation that underpins their commercial products and publisher monetisation strategies.

Prebid.org, Inc. is a US-based, Delaware non-stock, member-funded organisation that governs and stewards open-source header bidding and related adtech projects. It coordinates development of client-side, server-side, mobile, video, native, and identity components that publishers and adtech vendors use to run programmatic advertising auctions across multiple demand sources.

The organisation does not charge for use of its open-source software; instead, it is funded by dues-paying member companies from across the advertising technology ecosystem. Its primary users and economic stakeholders are web and app publishers, supply-side platforms, demand-side platforms, and other adtech firms that rely on its codebase and standards for publisher yield management, identity, and privacy tooling.
