The challenge

Wonderbly is a personalised children's book brand that came to us looking to scale their creative output and improve paid social performance across formats. We implemented a high-volume creative testing framework built around two strategic pillars: emotional resonance and social proof. Our approach leaned into authentic, recipient-led storytelling. This combines price reframe hooks, emotional permanence messaging, and testimonial-backed angles across UGC and static formats to attract and convert high-intent buyers.

The outcome

We produced 115 creatives per month across 25x3 UGC, 60x Statics, 20x Stills, and 10x Motion, enabling a continuous cycle of testing and iteration. Top UGC creatives delivered a 3.6x ROAS and a £23.04 CPA, while best-in-class static creatives achieved a £13.78 CPA which is -39% below the account average. Illustration-led formats drove scale while testimonial and social proof creatives delivered the strongest conversion efficiency, creating a complementary creative system that reduced CPA and improved account performance over time.

What our clients say
"We engaged Catalyst to drive UGC content production for Bolt Food across multiple markets, and they've done a great job coming up with culturally-relevant concepts and executing them to the highest standard."
"Catalyst have been a brilliant creative partner for us at Yonder. They genuinely feel like an extension of our team, easy to collaborate with, always bringing fresh ideas to the table, and never afraid to challenge our look and feel in the right ways. They've helped us level up with a more data-driven approach to creative, and unlocked content production at scale."
"Working with Catalyst has been a genuinely great experience for the Cleo team. As our partner for UGC assets and stills for paid ads, they've been patient, collaborative, and easy to work with throughout the whole process. We've had a couple of real grand slams come out of this partnership. Dan has been an amazing rep throughout, making the whole process smooth and stress-free."
"We've been working with Catalyst on our content creation and they've genuinely delivered. They're responsive, hold a high quality bar, and aren't afraid to reshoot when something isn't up to standard. The ads they've produced have transformed our TikTok and Meta campaign performance. Their approach is systematic across strategy, content, and data analysis, which is what actually drives the results. Highly recommended."
"Catalyst have been an excellent paid media partner for us at Dermalogica. Their ability to produce creative at scale has transformed our paid social performance and given Meta's algorithm the diversity it needs to work more efficiently. Beyond that, they've re-enabled us to expand into new channels like TikTok Shop with confidence, bringing the creative output and platform understanding needed to see results, we're excited about the future! Would highly recommend."
"The team were fantastic partners to work with across both creative and performance. Easy to collaborate with, proactive in bringing new ideas to the table and always focused on building a long-term partnership rather than just delivering work. Their responsiveness was genuinely best-in-class, which made a huge difference in a fast-moving environment like ours."
"Our performance on socials has stepped up to new levels since we started working with Catalyst. We've been able to keep moving with new creatives at a rate we couldn't do on our own, helped by the Catalyst team's brilliant responsiveness and turnaround times. Its been great to work with a regular team at Catalyst who have got to know our business, so our creative cycles are now feeling like a well oiled machine, thanks everyone."

"Working with Catalyst has helped us unlock real scale with UGC video testing.
