Piloting AI tools, running experiments, and staying current with the latest capabilities has become a full-time job for most marketing organizations. 🤹

What gets less attention is whether any of it is building toward something durable. Standalone tests rarely shift KPIs in a meaningful way, because the bottleneck was never the technology. It was the system the technology was supposed to plug into.

If there's no clear, governed process connecting creative production to performance, adding more tools makes the problem noisier. The CMOs seeing real movement are building the infrastructure that makes every tool they adopt actually matter.

Celtra works as that creative infrastructure. Book a demo today at https://hubs.ly/Q04CBNY20

Do you know which creative decisions separate strong campaigns from average ones? Matic Tribušon, Celtra's CPO, names 3:

1️⃣ The format you choose,
2️⃣ The experience you build
3️⃣ The variants you deploy

Our 9th Creative Insights Report shows how teams are acting on the third one. CTV creatives built with multiple variants grew 95% year over year in H1 2026, as brands tailored headlines, visuals and offers to specific audiences.

Getting a machine learning model to work in a notebook is one thing. Making it reproducible in production is where things get interesting, and occasionally humbling. 👀

Join us at AWS Events Community Day Adria in Ljubljana on October 22, where our Ivan Nikolov and Vid Stropnik will share their early experience of making that jump on AWS. They’ll cover versioning production models with Amazon SageMaker and tracking experiments with AWS-hosted MLflow. They’ll also talk about what they learned while migrating parts of their workflow from scikit-learn to PyTorch.

📍 Four Points by Sheraton Ljubljana Mons
🎤 Room: Plečnik 5 at 13:15

You signed up for DCO because it promised something specific: every impression would feel personal to whoever's looking at it. For most teams, that promise never held up, and no, it's not a targeting problem.

What's actually missing is a proper production setup: platforms can decide exactly who sees what, but assembling personalized creative only works if enough good components exist to build it from. Most teams can't produce at that volume, so campaigns quietly fall back on generic creative. 🫥

Read why that gap exists and how creative automation closes it:

What is Dynamic Creative Optimization (DCO), what it decides, and what creative supply it actually needs to work at scale.

Pause ads come with some pretty specific creative constraints: no sound, unpredictable exposure time, and limited room for storytelling. 😬

But Špela Vene, Sr. Product Manager at Celtra, argues that those limitations can actually make the creative stronger by forcing teams to be more focused and intentional. In our webinar with Wunderkind, she dives into what that means in practice, from messaging and visual hierarchy to motion, QR codes, and designing for the pause moment.

You can plan for almost anything. But you can’t plan for everything.

Sometimes it’s one word in an ad that suddenly needs changing. For Maciej Witalis, Sr. Growth Manager at Crypto.com, that used to mean getting the whole design team involved.

With Celtra, his team can now make the edit themselves, update every dimension and language, and get the creative back live; no Photoshop, no designer needed. Just make the change and move.

"Which version of our ad is working, and can we have more like it by tomorrow?"

Creative automation answers both. 🙂‍↕️ Your team signs off on one concept, and every size, market, and audience version is made from there, on-brand and without anyone rebuilding it by hand. Once they're live, you can see which versions people respond to, and that data goes straight into what you make next.
