My story

I started in New York at Google, running programmatic strategy for telecom, finance, retail and auto brands. At Pinterest I grew a partner's Shopping Ads revenue from US$150K to over US$1M a year. At Walmart I moved in house and delivered 30% year on year DTC growth at 4x ROAS.

During 2020 to 2022, my head of growth consulting work overlapped with my Meta role. For the consumer brand, I set the channel mix, creative voice and tracking, and revenue grew 617% in a year. As Global Performance Marketing Manager at Meta, I managed a US$23M global performance budget and cut the cost of each incremental sale by 32%.

At Amazon, I've worked across product marketing and ad products, including as global product marketing manager for Twitch Ads, where I helped launch Twitch Creator Sponsorships in Australia. At Amazon Music, I worked on lifecycle campaigns across Alexa, email and SMS that brought in 1.9M+ new app customers. I led go-to-market work for video and brand suitability products associated with US$6.7M in incremental revenue.

I started Ironpath to bring that big platform rigour to Australian brands that can't yet hire it full time.

What that means for you

Experience inside the platforms.

Working inside platforms has helped me understand ad delivery, auctions and measurement, including where the available data has limits.

I've run a brand's growth myself.

I consider the margin left after costs and how long it takes to recover customer acquisition costs, alongside reported advertising returns.

Recommendations with evidence and trade-offs.

I explain the evidence, assumptions and uncertainties behind recommendations so your team can make informed decisions.
