Celtra

Celtra is an enterprise-grade digital advertising creative platform designed to help brands, agencies, and media organizations produce, adapt, and activate advertising creative at scale across multiple channels, formats, and markets. The platform combines intelligent production automation, scalable personalization, and seamless activation workflows, enabling teams to generate thousands of creative assets — including rich media, dynamic, and video ads — without the excessive manual effort that typically bogs down creative operations. AI-driven tools allow users to predict ad performance before launch, optimize creative in real time, and apply data insights to improve campaign outcomes, while customizable on-brand templates empower marketers to build and deploy campaigns independently without requiring deep design expertise. Celtra is best suited for enterprise-level marketing and advertising teams — including in-house brand teams, creative agencies, and media publishers — operating in environments where creative complexity, governance, and speed are paramount, with notable customers including Spotify, Unilever, adidas, McDonald's, and NBCUniversal. Key use cases include large-scale campaign production, creative versioning and localization for global markets, dynamic and personalized advertising, and coordinating collaboration across internal and external stakeholders while ensuring assets meet all platform and media requirements prior to launch. With integrations across more than 100 demand-side and supply-side platforms and support for over 5 million creative assets annually, Celtra effectively bridges the gap between creative and media teams, reducing friction and driving operational efficiency throughout the entire advertising lifecycle.
