Anthropic appoints Theo Hourmouzis to lead ANZ as Sydney office officially opens

Anthropic is accelerating its push into Australia and New Zealand, appointing former Snowflake senior executive Theo Hourmouzis as general manager for the region while officially opening its Sydney office.

The move marks a significant local expansion for the AI company behind Claude, as competition intensifies among major global players seeking enterprise, government and research market share across Australia.

Hourmouzis brings more than two decades of technology leadership experience across Asia Pacific and joins Anthropic from Snowflake, where he most recently oversaw Australia, New Zealand and ASEAN operations.

His appointment signals Anthropic’s growing focus on turning enterprise AI from experimentation into commercial and operational impact.

“Organisations across Australia and New Zealand are thinking carefully about how to adopt AI and they want partners who take safety and rigor as seriously as they take the opportunity,” Hourmouzis said in a statement. “That’s what drew me to Anthropic.”

Anthropic said Hourmouzis will lead its expanding local team while shaping strategy around enterprise, government and research customers.

The company is already deepening ties with major organisations including Commonwealth Bank, Quantium and several research institutions, alongside recent partnerships with Canva and Xero.

Canva recently integrated its design tools into Claude, while Xero signed a multi-year deal to embed Anthropic’s AI into its financial ecosystem.

The Sydney office opening follows Anthropic’s broader international expansion across Tokyo and Bengaluru, with Seoul expected next.

For Australian marketers and digital leaders, the move reinforces how quickly AI competition is shifting from experimentation toward embedded enterprise infrastructure.

Anthropic is increasingly positioning Claude not simply as a chatbot, but as operational infrastructure for businesses, governments and institutions seeking safer, more disciplined AI deployment.

“Theo’s appointment reflects the conviction we share with the Australian government that AI can drive economic growth when it’s developed and deployed responsibly,” Chris Ciauri, managing director of international at Anthropic, added.

The news comes hot on the heels of a $25 billion AI investment from Microsoft and ChatGPT owner OpenAI which opened a Sydney office in August last year.
