d-Matrix raises $275M Series C to scale AI inference chip platform

Santa Clara–based d-Matrix closed a $275 million Series C round at a $2 billion valuation to expand its full-stack AI inference platform, which combines Corsair accelerators, JetStream networking and Aviator software for large language model serving. The oversubscribed round, led by a global consortium including BullhoundCapital, Triatomic Capital and Temasek with participation from QIA, EDBI and Microsoft’s M12, will fund global deployments and roadmap advances such as 3D memory stacking to deliver up to 10× faster, more energy‑efficient inference than GPU-based systems.
