Zeta Global acquires Y Combinator-backed AI startup Senso for GEO push

As AI chatbots replace search results, marketers must fight for visibility inside machine-generated answers instead of rankings.

• Zeta Global (NYSE: ZETA) signed a definitive agreement to acquire Senso, a Y Combinator-backed AI engineering company whose technology already powers Zeta's Generative Engine Optimization (GEO) product.
• Senso started as an AI research lab during the early wave of enterprise deep learning; co-founder and CEO Saroop Bharwani, who has 20-plus years working with regulated enterprises, will join Zeta along with the rest of the team.
• The deal brings AI engineering talent in-house and deepens Zeta's connectivity to frontier models including ChatGPT, Gemini, Claude and Google AI Overviews, paired with Zeta's existing Data Cloud.
• Senso's technology can identify who AI-generated answers reach and tie those insights to customer intelligence and marketing activation for measurable business outcomes.
• Zeta frames the acquisition as part of its broader 'intelligent AI infrastructure' roadmap, distinct from product announcements planned for its upcoming Zeta Live 2026 event.
• As consumers increasingly ask AI assistants for recommendations instead of searching, martech vendors are racing to control how brands get surfaced inside those AI-generated answers, not just in search rankings.
