One month after announcing its arrival in Australia, the AI giant behind Claude has appointed tech veteran Theo Hourmouzis as General Manager for Australia and New Zealand to lead its new Sydney headquarters.
Key Takeaways
- Theo Hourmouzis, a 20-year tech veteran and former Snowflake Senior VP, has been named General Manager to lead Anthropic’s expansion across Australia and New Zealand.
- The appointment coincides with the official opening of Anthropic’s Sydney office, the company’s fourth major hub in the Asia-Pacific region following Tokyo, Bengaluru, and Seoul.
- Hourmouzis is tasked with transitioning local customers – including Commonwealth Bank and Quantium – from AI experimentation to large-scale business impact.
- The AI giant has been busy deepening its ties with the Australian government of late, including a recent MOU and research partnerships with the Garvan Institute and Murdoch Children’s Research Institute.
Key Background
Anthropic confirmed the appointment of Hourmouzis on Tuesday. He’ll join the company following a stint at Snowflake, where he managed enterprise and public sector accounts across ANZ and ASEAN.
The AI giant, which was valued at US$380 billion following a $30 billion Series G round in February, said Hourmouzis’ primary mandate is to shape a regional strategy focused on safety and rigorous deployment for high-stakes industries like finance and healthcare.
“Organisations across Australia and New Zealand are thinking carefully about how to adopt AI, and they want partners who take safety and rigour as seriously as they take the opportunity,” said Theo Hourmouzis, Anthropic General Manager of Australia and New Zealand. “That’s what drew me to Anthropic.”
The Sydney expansion follows a surge in regional activity, with Australia currently ranking seventh globally in Claude usage per capita. In terms of total global Claude conversations, Australians now account for 1.6 per cent, while the US makes up more than 22 per cent.

"I've spent my career working with businesses and governments across this region, and the organisations that do best with AI will be the ones that pair ambition with discipline," Hourmouzis said in a statement released Tuesday.

Tangent
Hourmouzis' appointment comes as the company faces technical scrutiny. Independent reports from cybersecurity firms including TrustedSec and Veracode have claimed a decline in Claude’s code quality. Testing indicated that latest models introduced vulnerabilities in 52 per cent of coding tasks, leading Anthropic to investigate potential model degradation in its Opus series.
