Australia is racing toward the next generation of computing, and Firmus Technologies is stepping into that race with enormous momentum. The Nvidia-backed startup has raised a massive $327 million, giving it fresh firepower to build what could become the country’s largest network of green AI data centers. The latest round pushes the company’s valuation to roughly $600 million, underscoring investor confidence in its mission to tie AI infrastructure to clean energy from day one.
Firmus plans to channel the new capital directly into site development, long-term renewable energy contracts, and large-scale infrastructure build-outs across Australia. Its upcoming projects stretch from Perth and Sydney to Melbourne and Tasmania. Together, these sites could unlock up to 1.6 gigawatts of AI infrastructure capacity by 2028, placing Firmus among the most ambitious data-center developers in the region.
While the company kept investor names under wraps, it confirmed that existing backers doubled down. That continued support, especially with Nvidia’s ongoing involvement, signals strong belief in Firmus’s strategy of combining high-density computing with clean power. As next-generation Nvidia chips roll out, Firmus will be among the first in Australia to deploy them at scale.
Firmus Technologies began its journey in Singapore in 2020, founded by Oliver Curtis and Tim Rosenfield. Their shared mission was clear: build a new class of data centers that avoid the energy-heavy mistakes of older infrastructure. Both founders come from deep backgrounds in infrastructure, energy systems, and advanced computing. Because of this, renewable sourcing isn’t something they bolted on later, it’s a pillar of the company’s design philosophy.
From the start, they envisioned facilities that plug directly into Australia’s renewable-rich regions. Instead of relying on carbon-intensive grids, Firmus aims to use clean power as a primary building block. This approach has helped the startup stand out in a global market where many data-center companies still struggle with sustainability commitments.
Firmus is already putting its expansion plans into motion. Two major data-center campuses, in Melbourne and Tasmania, are now under development. These sites will be engineered specifically for heavy AI workloads, which demand enormous compute power but also require careful energy management to keep costs under control.
Both centres will run Nvidia’s upcoming GB300 chips, giving them a major performance jump without forcing energy consumption through the roof. These chips allow more computing per square meter, enabling Firmus to maintain high density while keeping sustainability benchmarks intact.
If the build-out stays on track, both locations are expected to go live by April, marking one of the earliest milestones in the company’s aggressive national rollout. This timeline places Firmus ahead of several competitors, many of whom are still in planning stages.
The demand for AI infrastructure is climbing at an unprecedented pace. Enterprises across banking, healthcare, logistics, retail, and public services are racing to integrate more AI into daily operations. Yet traditional data centers often struggle to keep up. They rely on power-hungry cooling systems and lack pathways to integrate clean energy efficiently.
Australia, meanwhile, is shifting toward a renewable-first grid faster than many developed nations. Solar and wind hubs across the country have reached a maturity level that makes long-term energy sourcing both predictable and cost-effective.
Firmus is tapping into that shift. By building AI campuses near renewable-rich zones—especially in Tasmania and the southern states, the company can offer enterprise customers a way to scale their AI workloads without adding pressure to the national grid or increasing carbon emissions. For global companies with strict sustainability goals, that proposition is becoming increasingly important.
Beyond the sustainability angle, Firmus’s expansion aligns with a growing national priority: building sovereign AI infrastructure. Countries around the world are realising that relying on overseas data-center operators or cloud providers for critical AI workloads poses long-term risks.
In this context, Firmus is positioning itself as a domestic partner capable of supporting both commercial and national-scale projects. Its upcoming campuses could play a key role in powering large-language models, scientific simulations, defence technology, medical research, and public-sector AI applications within Australia’s borders.
Co-CEO Oliver Curtis said the new funding allows Firmus to move into the next phase of Project Southgate, which expands development beyond Tasmania into four additional regions. He noted that the company is building “a new class of AI infrastructure, on Australian soil, that is purpose-built for scale, performance, and sustainability.” This, in his view, means creating high-value jobs and developing a critical national capability.
Meanwhile, Co-CEO Tim Rosenfeld highlighted Firmus’s long-term work on a vertically integrated “AI Factory” model. This allows the company to scale faster and more efficiently than traditional approaches. With demand for AI systems rising across every industry, he believes the new capital will ensure Firmus can meet that demand without compromising cost or sustainability.
Firmus’s rapid rise demonstrates how quickly the AI hardware landscape is shifting. A few years ago, the conversation around data centers focused mostly on cloud storage. Today, the battle is about compute density, energy efficiency, and securing enough clean power to feed exponentially growing AI models.
By anchoring its strategy around green AI data centers, Firmus is positioning itself at the center of that shift. As enterprises search for sustainable high-performance infrastructure, the company’s vertically integrated model, combining clean energy with next-gen Nvidia hardware, could become a defining advantage.
With hundreds of millions in new capital and several large campuses on the way, Firmus Technologies is emerging as one of the most important infrastructure players in Australia’s digital future.
