Infillion is a New York City–based advertising services company that offers a composable advertising platform. The platform breaks the ad supply chain into modular components that can operate independently or be orchestrated together, giving marketers flexibility while preserving visibility and control. It serves brands, agencies, and enterprises through a mix of managed services and self-service activation, enabled by an API-first approach and a focus on autonomous execution with humans retaining ownership of data, intelligence, and outcomes. Positioned to evolve with the advertising ecosystem, Infillion emphasizes an open, evolvable infrastructure designed to support campaigns across channels. In February 2026, the company announced the acquisition of Catalina Marketing, expanding its deterministic purchase data capabilities. The organization has pursued collaborations and integrations to enhance performance on the open web while maintaining transparency and control for its customers.
