Founder & Chairman


Johnny Hornby


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.

If agencies believe in the power of advertising, why do so few advertise themselves?

Johnny Hornby, founder, The&Partnership "Today’s advertising market is very different to what it was three years ago – and today trying to sell creative deployment as separate from media and data is looking increasingly antiquated, and far too slow."
