What is Celtra?
Celtra is an enterprise creative automation platform that helps large brands, agencies and media owners produce, serve and measure digital ads at scale. It connects the whole creative lifecycle, from generative AI production with brand controls through campaign activation to performance insights. Celtra is built for organizations that need thousands of on-brand ad variations across many markets, channels and formats, rather than for small teams making a few ads.
The platform has two main parts. Celtra Creative Automation helps marketing, creative and media teams launch complex omnichannel campaigns with AI-led production. Celtra Creative Enablement lets advertisers and publishers build and serve rich media and video ads. Dynamic Product Ads, predictive AI and creative services are available as add-ons. Celtra does not publish prices; each contract is custom and includes onboarding, training and technical support.

Celtra FAQ
What is Celtra used for?
Celtra is used by large brands, agencies and media owners to produce and manage digital ad creative at scale. Teams use it to create many versions of ads for different markets and channels, apply brand rules to AI-generated assets, serve rich media and video ads, build dynamic product ads and measure which creative elements perform best.
How much does Celtra cost?
Celtra does not publish prices. Every customer gets a custom contract based on the platform modules chosen, team size, creative volume, ad serving impressions and add-ons like Dynamic Product Ads or predictive AI. Larger and multi-year commitments get better unit pricing. Onboarding, training and 24/5 technical support are included at no extra cost.
Is Celtra good for small businesses?
Usually not. Celtra is an enterprise platform with custom contracts, onboarding and integration work, and it is designed for organizations producing large volumes of ads across many markets. Small businesses and freelancers usually get better value from self-serve ad design tools with monthly plans and faster setup.
Celtra vs The Brief (Creatopy): what's the difference?
Both help teams produce ads at scale. Celtra targets large enterprises with custom contracts, deep brand governance, rich media serving and creative performance intelligence. The Brief, formerly Creatopy, offers self-serve plans from $29 per month with an AI agent, resizing and ad serving on higher tiers. The Brief suits smaller teams, while Celtra fits global brands.
Does Celtra use generative AI?
Yes. Celtra includes enterprise generative AI production with automated brand governance, so generated images and copy follow brand rules before they reach a campaign. It also uses predictive AI, offered as an add-on, to score creative before launch and to show which creative elements are linked to better results once ads are live.
