What Cheerful Twentyfirst does
Cheerful Twentyfirst is a London-headquartered brand experience agency founded in 1985 and operating as a wholly-owned subsidiary of Aeorema Communications plc (AIM: AEO.L). The agency designs and delivers strategic live events, experiential campaigns, brand activations, hybrid and virtual events, and in-house moving image (brand film) production for global enterprise clients. Its flagship methodology is the proprietary Audience Playbook™, a behavioural-science and strategic-research framework that underpins all client engagements and is published as a series of white papers on attention, engagement and audience design.
The agency's service offering is structured as an integrated professional-services platform with five core product lines — Brand Experiences, Moving Image, Digital Engagement, Events & Production, and Internal Communications — supplemented by two monetised add-on modules: the Audience Playbook™ methodology and a Sustainability Measurement & ESG Reporting service. Revenue is generated through project-based and retainer-based professional-services fees for strategic, creative, production and on-site execution work. The agency operates from three offices (London HQ at New Cavendish Street, New York on Avenue of the Americas, and Amsterdam on Herengracht) and has delivered projects across London, New York, Cannes, Tokyo, Las Vegas, Austin, Barcelona, Paris, Edinburgh and San Francisco.
Customer concentration is spread across a marquee enterprise portfolio spanning media and publishing (The Wall Street Journal, The New York Times, BBC Studios, Hearst), technology and streaming (YouTube, Google, Roku, Vimeo-equivalent), advertising and marketing (Stagwell, Smartly, TripleLift, Basis Technologies), telecommunications (Vodafone), finance (Ramp, White & Case, Oliver Wyman), and live climate-conference production (Climate Group's Climate Week NYC). The agency sells primarily through senior-led, sales-driven enterprise relationships combined with profile-driven event presence at Cannes Lions, CES, SXSW and MIPCOM, and is positioned as a senior-team-led boutique consistently winning against agencies with materially larger headcounts.
