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.

Sorrell needs a medium-sized deal to realise his big ambition

Johnny Hornby’s The&Partnership, 49 per cent owned by WPP, is exactly the kind of agile “full service” model that Sorrell seems to have in mind. It may be too based in advertising for his new taste but all these marcoms groups need a strong ad base as Jones acknowledged when he bought a majority of Gravity Road.
