About ONE Marketing Agency

What Is Marketing Agency ONE?

Marketing Agency ONE is a full-service agency based in Berlin, operating across 38 countries. We build integrated campaigns that span every channel — from TV commercials and programmatic OOH to performance media, influencer partnerships and e-commerce funnels. The domain name says it all: marketingagency.one — one team, one brief, one result.

Unlike specialist agencies that hand off work between silos, ONE handles creative strategy, media planning, content production and analytics under a single contract. Global brands like Mercedes-Benz, Toyota, Schwarzkopf and Badoo work with us because they can brief once and trust the execution end-to-end — from campaign concept through final reporting.

Campaigns that move markets.

The Vertical Integration Advantage

When your campaign needs a TV spot, a creator brief, OOH placements, and a performance dashboard — most agencies make 6 phone calls. We walk down the hall. No brief lost in translation. No margin eaten by middlemen. No timeline stretched across three vendors.

Creative, production, media buying under one contract
Real-time optimization — not weekly agency reports
Budget goes into performance, not overhead

What Clients Say

Trusted by the Brands Behind the Brands

ONE didn't just run our campaign — they rebuilt the way we think about creator marketing. The results in Q4 were the best we've had in five years of influencer spend.

Head of Brand, FMCG — Europe

Launching a brand in 6 European markets simultaneously is exactly as chaotic as it sounds. ONE made it look effortless. Our ROAS targets were hit in week three. That never happens.

CMO, Consumer Electronics Brand

The event with Motsi Mabuse exceeded every KPI we set. 51 creators, flawless execution, and our Q4 app downloads were up 34% year-over-year. We've been working with ONE ever since.
