Omnicom Oceania appoints David Gatt to MD, Marketing Operations & Ecosystem Design

Omnicom Oceania has appointed David Gatt as Managing Director, Marketing Operations & Ecosystem Design, a newly created role focused on helping brands redesign how their marketing and customer ecosystem operates in an AI-driven environment.

Increasingly, clients are rethinking how agency, data and technology come together, moving beyond individual capabilities to more connected, scalable models. Gatt’s role responds to this growing demand, helping brands move from fragmented marketing execution to a connected system that delivers faster, more accountable and effective growth.

This shift also signals a move away from siloed execution toward more integrated, end-to-end marketing systems. As brands look to position marketing at an enterprise level, this requires resetting operating models, systems and structures to unlock the full value of AI and automation.

Gatt, known across the industry as Gatty, joins from Deloitte, where he led marketing transformation across sectors including Telco, Retail and Financial services. He brings more than 15 years’ experience with a focus on marketing automation, operating model design and translating technology capability into commercial outcomes.

Gatty’s role will focus on connecting the full power of Omnicom’s ecosystem, including OMNI, the advisory services of Credera and The Loom and broader data, technology and agency expertise into a connected, scalable model for clients.

Says Nick Garrett, CEO, Omnicom Oceania: “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.”

Says Gatt: “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.”

Based in Melbourne, Gatt will operate across Omnicom Oceania.
