Celtra

A leading Creative Management Platform (CMP) provider for enterprise brands, agencies, and media companies seeking to scale digital ad creative production and optimization

Celtra is an advertising technology company founded in 2006 and headquartered in the United States that specializes in creative automation and management for digital advertising. Its core platform — the Creative Management Platform (CMP) — enables brands, agencies, and media companies to design, produce, collaborate on, and distribute rich digital ad creative across display, video, social, and mobile channels from a single unified environment. By automating repetitive production tasks and enabling dynamic creative optimization (DCO), Celtra dramatically reduces the time and cost associated with scaling creative across markets, formats, and audiences. Celtra serves a global roster of enterprise clients including major consumer brands, media agencies, and publishers. The platform integrates with leading ad servers, DSPs, and social media platforms, positioning Celtra as a central hub in the modern creative workflow. Its emphasis on creative quality, brand consistency, and production efficiency has made it a recognized leader in the creative management and automation segment of AdTech. In the broader AdTech ecosystem, Celtra addresses a critical pain point: the explosion of digital channels and ad formats has made manual creative production unsustainable at enterprise scale. By combining collaborative design tools, asset management, versioning, and automated resizing and adaptation, Celtra enables marketing teams to maintain creative excellence while meeting the demands of always-on, multi-channel digital advertising. The company competes in the creative automation space alongside platforms such as Smartly.io, Bannerflow, and Flashtalking.
