Johnny began his career at agencies including Ogilvy, CDP and TBWA before setting up Clemmow Hornby Inge in 2001, along with co-founders Simon Clemmow and Charles Inge.
In 2013 Johnny launched The&Partnership, a new-model, WPP-backed, integrated agency network built for today’s complex industry landscape, spanning four continents and 1,500 people.
Today, The&Partnership is the UK’s largest and Europe’s fastest-growing independent agency network. It attributes this rapid expansion to the success of its in-sourced ‘&Model’ agencies, with multi-disciplined, on-site teams working alongside clients’ marketing departments in new, nimble ways, to a single bottom line; delivering innovative work to fit new marketing agendas.
Through championing The&Partnership’s visionary new agency model, Johnny has become a go-to industry commentator for the likes of the BBC and Sky News: commenting on issues ranging from ad fraud and brand safety to media transparency and political advertising – and most notably leading the industry in an advertiser exodus from YouTube last year.
He has hosted numerous sell-out events at Cannes, is a regular voice on industry panels, and has chaired the Marketing Group of Great Britain.
Outside of advertising, Johnny has sat on numerous boards including as a Trustee of the English Heritage Foundation, the Board of Governors at Marlborough College and of price comparison service Simplify Digital. He was also appointed chairman of Sentebale in January 2018.
