Zeta Global is an AI-powered marketing technology platform that helps large enterprises acquire, grow, and retain consumers. The core product is the Zeta Marketing Platform (ZMP), which combines an email service provider (ESP), a customer data platform (CDP+), and a demand-side platform (DSP) into a single system for running personalized campaigns across email, social, display, connected TV, and mobile. The platform's data layer — the Zeta SuperGraph — covers over 245 million U.S. adults with 2,500+ attributes per individual and over one trillion behavioral signals ingested monthly, underpinning targeting and personalization across all channels. Zeta sells primarily to large enterprises and agencies, serving 51 of the Fortune 100, and charges based on consumption — volume of messages sent, marketing decisions made, and data activated — rather than per seat. Revenue comes from two streams: direct revenue (~74%), where customers transact through Zeta-owned channels at higher margins, and integrated revenue (~26%), where Zeta activates campaigns through third-party platforms like Meta. Zeta follows a land-and-expand model: customers start with pilots, then expand to additional channels and use cases, driving ARPU from ~$709K in year one to ~$3.9M for customers on the platform five or more years. Net revenue retention was 120% in 2025. Zeta's growth strategy centers on its "One Zeta" push — expanding customers from single to multiple use cases — agency channel expansion, and the rollout of Athena, a newly launched AI agent that lets users manage campaigns through natural language. The late-2025 acquisition of Marigold added over 100 enterprise clients and a loyalty product, expanding cross-sell opportunities and European presence.
