Infillion

Infillion is an advertising technology company that operates a composable platform for marketers, describing itself as an agent-native, modular advertising system. Based in New York, the company provides advertising infrastructure built from more than 190 interoperable components, allowing marketers to assemble customized solutions rather than committing to a single rigid, proprietary stack. Its stated aim is to reduce inefficiency in the advertising industry by letting clients combine only the demand, supply, creative and data tools they need.

The platform brings together a portfolio of products spanning several parts of the advertising ecosystem. These include MediaMath, a demand-side platform; TrueX, an interactive video product; InStadium, focused on sports and venue environments; Gimbal, which provides location intelligence; and Catalina, which contributes retail intelligence, alongside interactive and enhanced video solutions. Clients can engage the platform through managed services, self-serve access or the company's Infillion Agent Connector for AI-driven operations, giving advertisers flexibility in how they run campaigns.

Infillion's capabilities touch advertising technology, media technology, retail media networks and location and data intelligence. Its location intelligence and place-based, venue and stadium products connect it to the physical and out-of-home advertising environment, enabling targeting and measurement tied to real-world locations. Within an out-of-home directory, Infillion functions as a technology and data vendor rather than a media owner or producer, supplying the platforms, location data and interactive video tools that advertisers and agencies use to plan, activate and measure digital and place-based campaigns across connected channels at national scale.
