What PubMatic, Inc. does

In the company’s own words

PubMatic, Inc. (NASDAQ: PUBM) operates as an independent, artificial intelligence-powered advertising technology company delivering digital advertising performance through its integrated technology platform. The company's website is www.pubmatic.com.

The platform connects buyers, publishers, data providers, and commerce media networks on a unified infrastructure to facilitate programmatic advertising transactions. PubMatic serves four primary customer types: publishers including large omnichannel media companies across display, video, mobile web, app, and connected television formats; buyers comprising demand-side platforms, agency holding companies, independent agencies, and advertisers; data partners and curators leveraging the platform for audience solutions; and retail and commerce media participants using the platform for monetization opportunities.

The company generates revenue primarily through fees charged to publishers as a percentage of advertising impression values monetized on its platform. Additional revenue streams come from value-added features and functionality including Connect, which provides data and insights to buyers; Activate, enabling direct deals across publisher inventory; OpenWrap, a header bidding solution; and emerging AI-powered products such as Intelligent Yield for publishers and Convert, a commerce media solution.

PubMatic operates a global business with distributed critical infrastructure and go-to-market presence in major advertising markets worldwide. The platform processes hundreds of billions of ad impressions and trillions of advertiser bids daily, generating enormous data volumes that the company harnesses through machine learning and artificial intelligence capabilities to optimize outcomes for both publishers and buyers.

The company owns and operates proprietary software and hardware infrastructure globally, providing cost advantages compared to public cloud alternatives. Its specialized cloud platform is designed for real-time programmatic advertising transactions while maintaining transparency, quality controls, and data-driven decision-making capabilities. PubMatic competes with other supply-side platforms, private SSPs in various markets, and technology company divisions, differentiating itself through its AI-driven infrastructure, omnichannel capabilities, independence from media ownership, and demonstrated ability to extend header bidding infrastructure across emerging ad formats including mobile, video, and connected television.
