Jon Wilkins, chairman of creative agency Karmarama, now part of Accenture Interactive, and Nils Leonard, co-founder of creative studio Uncommon London, talk about the challenges of launching a start-up agency, the possible future for agency networks and why now is the time for agencies “to create stuff”. We also learn why keeping a punk-rock sensibility is vital, when and how to fire a client and why it’s important to invest in sturdy furniture when trying to woo potential big-spending accounts.
