The Assembly will be responsible for developing NetJets' brand strategy and advertising, working alongside the digital agency Fortune Cookie and the direct marketing agency Lida.
NetJets, which claims to be the largest business jet company in Europe, targets high-net-worth individuals and corporate audiences through business and high-end lifestyle magazines, the Financial Times, and business- and news-focused TV channels.
The Assembly will be briefed to create a new campaign for the company. M&C Saatchi won an internal branding project for NetJets last year but is not on its roster.
Last year, AKQA was appointed to work on NetJets' digital account and has since relaunched its website.
