BullhoundCapital leads $275m investment into AI inference leader d-Matrix

d-Matrix, the pioneer in generative AI inference for data centres, has closed $275 million in Series C funding, valuing the company at $2 billion and bringing the total raised to date to $450 million. The new capital will accelerate global expansion and support large-scale deployments of the world’s highest-performing, most efficient data centre inference platform for hyperscale, enterprise, and sovereign customers.

The oversubscribed round attracted leading investment firms across Europe, North America, Asia, and the Middle East. Co-led by a global consortium of BullhoundCapital, Triatomic Capital, and Temasek, the round also included new participation from the Qatar Investment Authority (QIA) and EDBI, alongside follow-on participation from M12, Microsoft’s Venture Fund, as well as Mirae Assets, Industry Ventures, and Nautilus Venture Partners. 

d-Matrix’s full-stack inference platform combines breakthrough compute-memory integration, high-speed networking, and inference-optimized software to deliver 10× faster performance, 3× lower cost, and 3–5× better energy efficiency than GPU-based systems. Solutions powered by d-Matrix’s Corsair™ inference accelerators, JetStream™ NICs ,and Aviator™ software can produce up to 30K tokens per second at 2ms per token on a Llama 70B model. The platform’s compute-dense design allows customers to run up to 100B-parameter models incredibly fast in a single rack.

This step-change in performance and efficiency directly addresses growing AI sustainability challenges. By enabling one data centre to handle the workload of ten, d-Matrix offers a clear path to reducing global data centre energy consumption while enabling enterprises to deliver cost-efficient, profitable AI services without compromise.

“From day one, d-Matrix has been uniquely focused on inference. When we started d-Matrix six years ago, training was seen as AI’s biggest challenge, but we knew that a new set of challenges would be coming soon,” said Sid Sheth, CEO and Co-founder of d-Matrix. “We predicted that when trained models needed to run continuously at scale, the infrastructure wouldn’t be ready. We’ve spent the last six years building the solution: a fundamentally new architecture that enables AI to operate everywhere, all the time. This funding validates that vision as the industry enters the Age of AI Inference.”

“As the AI industry’s focus shifts from training to large-scale inference, the winners will be those who anticipated this transition early and built for it,” said Per Roman, Founding Partner of BullhoundCapital. “d-Matrix stands out not only for its technical depth but for its clear strategic vision. The team understood before anyone else that inference would define the economics of AI — and they’re executing brilliantly on that insight.”
