When Elsa Beaumont was tapped last year by Treasury Wines Estate – home of the mighty Penfolds – the former exec at global hot shops like Mother and Big Spaceship, and her colleague Ben Oliver, who’s running Treasury’s internal media unit at Splash, were worried. Could they beat all the warnings that come from agencies when brands try to go in-house with capabilities all previously outsourced: talent is hard to attract and keep stimulated, burnout is a high risk and any cost benefits would be shortlived. Burnout risk turned out to be true but the talent, quality and volume of work is rocking, they say  – and now Splash is preparing for a global rollout across Treasury Wines’ international markets. The upside is faster turnarounds, tighter links with marketing teams and better output than what was possible by just using agencies. And in the case of media, Oliver is chasing down transparent digital media buys and practices that he never quite got in life before Splash.
