A Creative Digital Agency

Creating Experiences.

A Creative Digital Agency Bridging the gap between creative and all media.

Creativity and design are more than an asset, it’s communication. And they need to work in cross-format unison.

When designing concepts and adverts, we also need to think about the media and their respective formats. A TikTok ad has different communication mechanics than an outdoor ad or TV ad.  Our design team is unique as it truly understands each format by working directly with each media specialist, to design and create effective adverts that achieve their true potential and are 100% fit for purpose.

Cineworld

Making Cineworld the First Choice for Every Film

Cineworld’s UK search interest had been declining, with spikes mostly driven by major film releases. One Day Agency helped shift focus from individual titles to the Cineworld brand, using clear USP-led messaging and loyalty campaigns to build stronger, more consistent brand engagement.

Forlax

Forlax partnered with One Day Agency to grow awareness and pharmacy sales in Poland. Within strict pharma regulations, we developed a multi-channel campaign using tailored creative, AI video, design and human storytelling to connect with five key audience segments.

Dip & Doze

Bringing Comfort and Craft to Life Through Creative

Dip & Doze partnered with One Day Agency to boost visibility, conversions and audience reach. With search demand showing a “spike and fade” pattern, our focus was on building a more consistent market presence for the premium sustainable bedding brand.

Cinema City

Following Cineworld’s success, One Day Agency adapted the same creative framework for Cinema City, tailoring it to the brand and market. With limited assets available, we used generative AI to turn static imagery and Cineworld footage into dynamic, consistent video content.
