Celtra is an enterprise creative automation platform for digital advertising. Founded in 2006 and headquartered in Boston, Massachusetts, the company connects the creative lifecycle, from production through activation and analytics, into a single operating model used by brands, agencies, and media owners.
The platform's core capability is producing large volumes of on-brand ad creative automatically. Generative AI-powered production is combined with automated brand governance, so creative variations are generated within brand guidelines at scale. Celtra's performance intelligence scores creatives before launch and tracks which creative elements drive results, feeding that data back into generation. The platform also supports live-data creatives that respond in real time to pricing, inventory, and market changes across more than 100 media platforms, plus Dynamic Product Ads for custom, on-brand catalog advertising and rich media and video ad creation and serving.
Celtra is designed for marketing leaders scaling ad output, creative teams eliminating repetitive versioning work, media teams producing channel-specific variants, and media owners building premium ad products. The company states creative teams can produce ads around five times faster, and its clients have included Spotify, adidas, Unilever, and Hearst.
Celtra is a web-based SaaS platform. Pricing is fully custom and sales-driven: packages are built around the platform chosen (Creative Automation or Creative Enablement), team size and production volume, ad serving volume, and add-ons such as Dynamic Product Ads, predictive AI, and custom APIs. Volume discounts and multi-year agreements are available; prospective customers must contact the sales team for a quote.
