Submer has acquired Radian Arc Operations Pty Ltd, an established provider of infrastructure-as-a-service (IaaS) for telco-focused, sovereign GPU cloud services, completing Submer’s full-stack AI cloud offering that spans core datacenters to edge compute and enables rapid, low-latency deployment for telecom operators and enterprises worldwide.
Submer, a global leader in AI infrastructure, has acquired Radian Arc Operations Pty Ltd to create a comprehensive, sovereign AI cloud offering that bridges core datacenter capacity with distributed edge compute. This strategic move unites Submer’s InferX platform—launched earlier as an NVIDIA Cloud Partner—with Radian Arc’s proven carrier-embedded GPU infrastructure, delivering high-performance, low-latency AI services directly within telecom networks.
Radian Arc’s platform is already operational with more than 70 telecom and edge customers worldwide, powering thousands of GPUs for real-time applications such as cloud gaming and AI workloads. By embedding compute inside carrier networks, it ensures data remains processed locally, preserving sovereignty while leveraging telco systems for billing and operations.
“This acquisition of Radian Arc completes our full-stack cloud infrastructure,” said Patrick Smets, CEO at Submer. “Bringing Radian Arc together with InferX, our AI operations and delivery platform, forms a dual-plane, sovereign, telco-focused cloud offering that is highly competitive in today’s AI datacenter market.”
“We have built our platform in close cooperation with our customers and partners, allowing us to develop a powerful model that demonstrably works at scale,” said David Cook, CEO at Radian Arc. “By joining Submer’s established partner ecosystem, we are now in a position to accelerate delivery of sovereign AI infrastructure faster and with lower latency to telecoms operators worldwide.”
The acquisition enhances Submer’s ability to serve as a single accountable partner for AI infrastructure, spanning:
“Built on ten years of liquid cooling leadership, Submer has evolved into a full-stack AI datacenter provider, fully accountable from chip to operation. Joining forces with the RadianArc team and their edge compute platform is an exciting next step, further strengthening our position as the single accountable partner for end-to-end AI infrastructure,” added Patrick Smets.
This transaction positions Submer to meet surging demand for sovereign, distributed AI compute while delivering energy-efficient, high-density solutions that support telco operators and enterprises in scaling AI operations effectively.
