Firmus Technologies partners with NVIDIA to build data center in Indonesia, leveraging lower costs and energy availability.

Firmus Technologies, an Australian startup that pivoted from cryptocurrency mining to AI infrastructure, is building its first data center in Indonesia through a partnership with Nvidia, marking the next phase of its expansion across the Asia-Pacific region.

Since its inception in 2019, Firmus has grown rapidly. The company has raised over $1 billion in total funding and achieved a $5.5 billion valuation following a $505 million Series funding round led by Coatue in April 2026, with Nvidia participating as an investor. Nvidia remains both a hardware partner and investor in the company.

Firmus deploys Nvidia's GB300 GPUs across its data center operations. The company's flagship initiative is Project Southgate, a multi-gigawatt data center expansion in Australia targeting completion by 2028, with the initial phase carrying an AU$4.5 billion price tag. The project spans facilities in Tasmania and Melbourne, emphasizing immersion and liquid cooling techniques to reduce energy consumption compared to traditional air-cooled facilities.

The company already operates a regional hub in Singapore and is competing alongside operators such as CDC and STT GDC, both of which maintain partnerships with Firmus, to capture growing demand for data center capacity across Asia-Pacific.
