Will Watt

Director of Product

At Join In, the London 2012 volunteering legacy charity, Will conceived and developed all creative, communications and campaigns including the #BigThankYou campaign with BBC Sports Personality of the Year (trending globally on Twitter in 2014 and 2015).

Will also devised Join In’s work into the value of sports volunteering in the UK which has become a case study in Lord Gus O’Donnell’s ‘What Works Wellbeing’ centre. This was followed up with leading behavioural science research on how to recruit and retain volunteers. Both of these pieces of work built on the work of Simetrica and Daniel Fujiwara.

Previously, Will studied Law at university before working in publishing for the NME and then as Publisher of Viz comic. At Viz Will doubled revenue and subscriptions and published the bestselling Viz ‘Profanisaurus’. Will then moved into digital with the launch of a pioneering joint venture with the BBC that turned into a major sustainability initiative for the Prince of Wales involving M&S, Eurostar, B&Q and other leading brands.

As a volunteer, Will founded King’s College Old Boys F.C. in 1998 and in 2012 founded The Swimmer, a community swimrun across London which has featured in the national press. Will also runs the U9s age group at his son’s Rugby Club, Old Alleynians.
