Infillion

Infillion is the first composable advertising platform, built to help businesses operate with greater flexibility, transparency, and efficiency as the advertising ecosystem evolves. Built from category-defining capabilities, including MediaMath, TrueX, Gimbal, and Drawbridge, Infillion deconstructs the advertising supply chain into modular, agentic-ready components. These components can operate independently or be orchestrated together—giving marketers flexibility without sacrificing control or visibility. Infillion provides a single, transparent infrastructure for brands, agencies, and enterprises, supporting managed service execution, self-service activation, and API-first automation. Designed for the agentic era, the platform enables autonomous execution while ensuring humans retain full ownership of data, intelligence, and outcomes. Headquartered in New York City, Infillion powers leading brands and agencies worldwide—delivering advertising infrastructure that is open, composable, and built to evolve with what’s next.
