Horizon Media Holdings Advances Open Ecosystem with HorizonOS Labs Cohort 2

Horizon Media Holdings has announced the second cohort of its HorizonOS Labs innovation engine, selecting 15 partner companies to test and scale emerging marketing technologies. This initiative aims to replace legacy agency silos with a more transparent, flexible model that prioritizes proven business outcomes over theoretical AI capabilities. For the marketing technology sector, this represents a significant shift toward integrated, agentic systems where intelligence and automated decisioning are collapsed into a single, continuous workflow.

Horizon Media Holdings selected the 15 partner companies for Cohort 2 from a pool of more than 600 submissions received during its 2026 Request for Information (RFI) process. The selection criteria focused on five core pillars: AI Visibility & Agentic Experiences, Custom Bidding & Activation Intelligence, Agentic Analytics & Decision Intelligence, Creative Intelligence, and Marketing & AI Infrastructure. According to John Koenigsberg, EVP and Head of Platform Partnerships, the program is designed to help clients navigate a market saturated with AI claims by validating which tools actually deliver measurable results in real-world campaign environments.

The initiative highlights a broader industry transition where marketing is bifurcating into intelligence and decisioning layers. Intelligence is moving closer to the supply path and consumer attention signals, while decisioning is becoming increasingly automated and continuous through AI systems that optimize campaigns in real-time. This cohort places a specific emphasis on interoperability and emerging standards like the Model Context Protocol (MCP), ensuring that new tools function as part of a connected ecosystem rather than isolated silos. Many of the selected partners are already operating within live environments to influence bidding, pacing, and creative selection.

HorizonOS Labs, which launched in late 2025, serves as a repeatable system for integrating innovation into the agency's broader operating system. Bob Lord, President of Horizon Media Holdings, noted that the rise of AI necessitates a reset in client expectations, moving away from closed ecosystems toward models that connect data and technology with human insight. Following the success of the inaugural cohort—where several partners have already transitioned into active client use—Horizon plans to launch two additional cohorts later in 2026 to maintain a steady pace of technological evaluation and deployment.
