What One Day Agency does
One Day Agency is a privately held integrated advertising and marketing agency headquartered in Manchester, with additional offices in London, Warsaw, Paris, and Berlin. Founded in November 2019 by Ricardo Seixas, the firm positions itself as a single, non-siloed team delivering creative, digital, media planning and buying, OOH, TV/VOD, radio, and influencer services to brands ranging from small e-commerce businesses to F1 teams and public-sector bodies.
The agency's service stack rests on a small suite of proprietary ad-tech tools — an OOH Media Planner, an OOH Benchmarking pricing tool, a Media Mix Calculator, and an internal Creative Hub — supplemented by an "AI Creative" service that applies generative AI to scale image and video production for campaigns (e.g., winning the Polish Tourism Organisation generative AI pitch). It holds Google Premier Partner and Meta Business Partner status, enabling execution across major biddable and social platforms.
Commercially, One Day Agency operates on professional-services fees and media commissions via project-based and retainer engagements, with senior strategists engaged directly on client work rather than handed off to account teams. Majority ownership sits with The Behrens Group following a June 2024 acquisition, providing capital for the reported 60% year-over-year revenue growth and ongoing European expansion.
