Australia – The Oceania arm of Omnicom Group has appointed David Gatt as Managing Director for Marketing Operations and Ecosystem Design, a newly created position aimed at helping brands redesign their marketing and customer ecosystems in an increasingly AI-driven environment.
Based in Melbourne, Gatt will work across Omnicom Oceania and focus on supporting clients as they rethink how agency capabilities, data, and technology can be integrated into more connected and scalable marketing models.
The appointment comes as companies increasingly reassess their marketing operating models, moving beyond fragmented execution toward systems that integrate data, technology, and agency capabilities. According to the company, this shift reflects growing demand from brands seeking more accountable and effective growth through coordinated marketing ecosystems.
In the role, Gatt will focus on connecting the capabilities of Omnicom’s wider ecosystem, including the group’s marketing orchestration platform Omni as well as advisory services from Credera and The Loom, alongside broader data, technology, and agency expertise.
Gatt joins from Deloitte, where he led marketing transformation initiatives across sectors such as telecommunications, retail, and financial services. He brings more than 15 years of experience, with a focus on marketing automation, operating model design, and translating technology capabilities into commercial outcomes.
Nick Garrett, CEO of Omnicom Oceania, said the role reflects evolving client needs around marketing transformation.
“The vast majority of conversations we’re having with clients right now and what we’re seeing in new business, is about operating models and a broader need for marketing transformation capability, not just marketing execution. It’s no longer just about how we evolve our own business around a client, but how we help clients redesign theirs.
I’ve worked closely with Gatty previously and have seen the commercial impact he can deliver. He is as talented as he is nice and will be a huge asset to our clients’ businesses. There are very few people in the Australian market with the depth of expertise in this space that Gatty brings, and that’s exactly why this role is so important for us”.
Gatt said “The pressure on brands to unlock value from AI has never been greater, but most are using it to go faster down the same road. The work I’m most excited about is helping brands ask whether they should be on that road at all and designing something better. Omnicom has everything needed to do that at real scale”.
