0%Zeta Global has announced AthenaOS, an enterprise intelligence operating system that combines company data with Zeta's market intelligence to drive business decisions. Built on the Zeta Data Cloud, the system dynamically organises around business objectives and learns from outcomes to improve future decisions. The platform includes Athena MCP, a headless solution enabling enterprises to integrate Zeta's intelligence into existing applications and workflows. Zeta is also developing the Athena Inference Model in collaboration with Fireworks, using NVIDIA Nemotron for specialised business use cases. AthenaOS is currently in limited internal beta, with public beta expected later this year and general availability planned for Q1 2027. Zeta has also begun exploring development of a specialised chip with semiconductor partners to deliver faster intelligence through a capital-light approach.
Zeta Global has entered into an agreement to acquire Digital Audience, a data infrastructure company that expands identity and activation capabilities across the digital ecosystem. Already integrated with Zeta, Digital Audience will enhance Zeta's ability to connect customer intelligence to activation across all channels. The acquisition will add an experienced team of data and AI engineers to Zeta's workforce. It will also strengthen Zeta's European presence and add established enterprise relationships in the region. "Enterprise intelligence only creates value when it can be put to work and improve outcomes," said David A. Steinberg, co-founder, chairman and CEO of Zeta Global. Digital Audience will help Zeta clients activate customer data more efficiently and measure impact across channels. Following the transaction close, Zeta will work with the Digital Audience team to ensure continuity for customers.

The acquisition will bring AI engineering talent in-house and deepen Zeta's connectivity to frontier models including ChatGPT, Gemini, Claude and Google AI Overviews. Senso will help enterprises optimise how brands reach customers across leading AI platforms and identify who AI-generated answers are reaching. Senso's co-founder and CEO, Saroop Bharwani, will join Zeta along with his team. Bharwani brings over 20 years of experience working with regulated enterprises. He founded Senso as an AI research lab during the early wave of enterprise deep learning. Bharwani will speak at Zeta Live on 8 October 2026 about how GEO is reshaping brand discovery.

CEO David Steinberg reported clients using Athena are achieving returns exceeding 600% on marketing spend, with targets set at 1,000%.
