PubMatic

PubMatic operates a two-sided adtech platform connecting media owners and buyers in programmatic advertising. It creates value by helping publishers increase yield, control inventory packaging and improve addressability, while helping advertisers and agencies access curated premium supply with more transparent deal execution. Its platform spans SSP infrastructure, header bidding, identity and data connectivity, yield optimisation, retail media enablement and buyer activation workflows.

PubMatic is an independent public advertising technology company that operates infrastructure for digital media trading, with a core focus on publisher monetisation and programmatic supply. Its main business is its supply-side platform, which helps publishers, app developers and CTV media owners sell advertising inventory across web, in-app and connected TV. It also sells adjacent tools for header bidding, identity orchestration, audience signal sharing, yield optimisation and retail media monetisation.

Beyond publisher tools, PubMatic has expanded into buyer-facing workflow products such as Activate, Auction Packages and AgenticOS, which help advertisers and agencies access curated premium supply and execute programmatic deals. The company primarily makes money by taking a percentage of media spend transacted through its platform, supplemented by software-like platform access and workflow products tied to data, optimisation and marketplace functionality.
